00:00:01,900 --> 00:00:05,600
Hi friends, welcome to 'Python Scripting for Automation' course.

3
00:00:05,900 --> 00:00:09,400
Friends, Python is very popular in different areas,

4
00:00:09,800 --> 00:00:11,800
and one of the area is automation.

5
00:00:12,600 --> 00:00:16,100
Let me show you the different areas in which your Python is popular.

6
00:00:17,300 --> 00:00:20,700
See Python is popular in application development side,

7
00:00:21,400 --> 00:00:25,300
I mean like Web-Application development, API development, and

8
00:00:25,300 --> 00:00:29,700
some GUI Application Development for your Desktops, right,

9
00:00:30,100 --> 00:00:32,299
and then Data Analysis, Data Analytics,

10
00:00:33,400 --> 00:00:37,200
Artificial Intelligence. You know AI is very, very popular,

11
00:00:37,400 --> 00:00:41,100
right, and Python is extensively used in your AI side.

12
00:00:42,400 --> 00:00:46,000
Then for Web Scraping and Text Processing, Selenium Testing,

13
00:00:46,300 --> 00:00:50,500
and then Automation. Not only these areas, there are many more

14
00:00:50,500 --> 00:00:51,700
other areas as well,

15
00:00:51,900 --> 00:00:55,800
but these are the major areas in which your Python is popular.

16
00:00:56,700 --> 00:01:01,400
See if Python is popular, then definitely it has some unique

17
00:01:01,400 --> 00:01:04,900
features compared to other programming languages or

18
00:01:04,900 --> 00:01:07,099
scripting languages, right?

19
00:01:07,400 --> 00:01:10,500
So because of that only your Python is popular. Then what

20
00:01:10,500 --> 00:01:13,500
are those? Why Python is popular, right?

21
00:01:13,500 --> 00:01:14,700
Let me go through that.

22
00:01:14,700 --> 00:01:18,800
The very first one is, Python is easy to learn because of

23
00:01:18,800 --> 00:01:23,000
its simple syntaxes. See if you compare your Python with

24
00:01:23,000 --> 00:01:25,400
other programming or scripting languages,

25
00:01:25,400 --> 00:01:30,000
it is having very simple syntaxes. You know, if you have very simple

26
00:01:30,000 --> 00:01:34,300
syntaxes then you can easily learn that. Once you learn

27
00:01:34,300 --> 00:01:36,900
it you can easily apply that for your real-time scenarios,

28
00:01:36,900 --> 00:01:41,400
right? So this is one of the point to become your Python

29
00:01:41,400 --> 00:01:46,800
as popular language. Then many modules - predefined and third-party

30
00:01:46,800 --> 00:01:50,900
modules. See guys in case if you know, if you have some basics

31
00:01:50,900 --> 00:01:52,300
of Python then it's okay,

32
00:01:52,300 --> 00:01:55,300
otherwise just assume that module is nothing but predefined

33
00:01:55,300 --> 00:01:57,200
Python program or Python Script,

34
00:01:57,200 --> 00:01:58,900
[no audio]

35
00:01:58,900 --> 00:02:05,900
right? See just assume that working with the database is a common

36
00:02:06,000 --> 00:02:08,699
scenario at your application development site.

37
00:02:09,900 --> 00:02:12,300
Now suppose if you are going to develop some application,

38
00:02:13,699 --> 00:02:16,400
and in that you need to write some code to connect with your

39
00:02:16,400 --> 00:02:20,200
database, to run some queries with your database, right?

40
00:02:20,200 --> 00:02:21,700
That is a common task.

41
00:02:22,100 --> 00:02:24,300
That's why for that task

42
00:02:24,300 --> 00:02:25,600
you don't need to write code.

43
00:02:27,300 --> 00:02:31,800
See whenever if it is a common or repetitive task for that

44
00:02:31,800 --> 00:02:33,500
type of tasks already

45
00:02:33,500 --> 00:02:37,500
someone has written a Python Script, and that is called actually,

46
00:02:37,500 --> 00:02:41,500
we are calling that as a module. Now, you can use that module

47
00:02:41,500 --> 00:02:44,900
and directly you can use that in your application development

48
00:02:44,900 --> 00:02:48,800
code, right, so that you don't need to write your code

49
00:02:48,800 --> 00:02:51,900
from scratch to work with database, right.

50
00:02:52,400 --> 00:02:56,000
So that means you are saving time, sometime, and you are going

51
00:02:56,000 --> 00:02:58,400
to reduce the number of lines in your code.

52
00:03:00,000 --> 00:03:05,200
Right. So because of many modules your Python is popular not only

53
00:03:05,200 --> 00:03:06,200
working with database,

54
00:03:06,900 --> 00:03:09,000
there are so many modules for different areas.

55
00:03:10,500 --> 00:03:14,000
I am not sure whether you know or not as of now with your

56
00:03:14,000 --> 00:03:18,300
Python there are around 1,47,000 modules are there.

57
00:03:19,400 --> 00:03:23,200
But don't worry, you don't need to learn all 1,47,000 modules.

58
00:03:24,000 --> 00:03:28,700
Based on in which area you are interested, or in which area

59
00:03:28,700 --> 00:03:30,900
you are going to use your Python, based on that

60
00:03:30,900 --> 00:03:32,700
you have to know some of the modules.

61
00:03:33,800 --> 00:03:38,800
That's it. Right. Then, code length is very short because of third-party

62
00:03:38,800 --> 00:03:42,400
modules. Just now we discussed that. To work with the database

63
00:03:42,400 --> 00:03:45,400
if there is no predefined Python Script, what we have

64
00:03:45,400 --> 00:03:50,000
to do? We have to write code from scratch, but luckily if

65
00:03:50,000 --> 00:03:52,900
we have a third-party module for your requirement,

66
00:03:53,800 --> 00:03:55,200
then you don't need to write code, right?

67
00:03:55,200 --> 00:03:58,000
You can use that directly, so that you are going to reduce

68
00:03:58,000 --> 00:03:59,500
your code length.

69
00:04:01,100 --> 00:04:04,000
Right. Then platform-independent.

70
00:04:04,900 --> 00:04:07,400
Just assume that you are going to work as a,

71
00:04:07,400 --> 00:04:09,100
suppose middleware admin,

72
00:04:09,100 --> 00:04:11,100
[no audio]

73
00:04:11,100 --> 00:04:14,800
right. Let's say in middleware you're going to work as a Tomcat

74
00:04:15,700 --> 00:04:21,600
application admin, right, and you know you can install your

75
00:04:21,600 --> 00:04:25,200
Tomcat, or you can install and run and manage your Tomcat

76
00:04:25,200 --> 00:04:28,500
on Windows operating system as well as some Unix-like systems,

77
00:04:28,500 --> 00:04:32,400
right? You can install your Tomcat on both operating systems.

78
00:04:33,500 --> 00:04:36,200
I mean in different operating systems you can run your Tomcat.

79
00:04:36,800 --> 00:04:43,700
Now assume that I want to automate some tasks on my Tomcat.

80
00:04:43,900 --> 00:04:46,200
I don't know Python, right?

81
00:04:46,600 --> 00:04:50,000
So first observe the Windows side. If you're working at Windows

82
00:04:50,000 --> 00:04:53,300
side to automate your task by default with your Windows

83
00:04:53,300 --> 00:04:57,800
you have either batch script or PowerShell. You can use any

84
00:04:57,800 --> 00:05:01,200
one of the script and you can automate your task. But same

85
00:05:01,200 --> 00:05:06,200
script would not work at your Unix-like systems. Then if

86
00:05:06,200 --> 00:05:08,900
you come to Unix side, again you have to write some separate

87
00:05:08,900 --> 00:05:13,700
shell script to automate your task. See for same task because

88
00:05:13,700 --> 00:05:15,600
of different platforms

89
00:05:15,600 --> 00:05:19,000
you're separating separate scripts to automate your task.

90
00:05:19,600 --> 00:05:24,100
But if you know Python you can write only one Python Script

91
00:05:24,100 --> 00:05:26,900
such that that script will work with your Windows operating

92
00:05:26,900 --> 00:05:29,500
system as well as your Unix-like systems.

93
00:05:30,300 --> 00:05:35,600
So this is the reason, because of this we are calling Python

94
00:05:35,700 --> 00:05:40,100
is platform independent. Now, you don't need to write two different

95
00:05:40,100 --> 00:05:42,300
scripts to work with the different operating systems, right?

96
00:05:42,600 --> 00:05:45,600
You can use only one script, Python Script. Python will work

97
00:05:45,600 --> 00:05:47,400
actually with the different operating systems.

98
00:05:47,400 --> 00:05:49,400
Whatever the script you are going to run on one operating

99
00:05:49,400 --> 00:05:52,300
system same script you can write with other operating systems as well,

100
00:05:53,900 --> 00:05:57,400
right. So because of this also Python is very, very popular,

101
00:05:58,700 --> 00:06:04,800
right. Fine. Then finally Python supports

102
00:06:04,800 --> 00:06:07,200
functional as well as OOPS concepts.

103
00:06:07,200 --> 00:06:10,000
[no audio]

104
00:06:10,000 --> 00:06:12,800
Right. That means not only Python guys,

105
00:06:12,900 --> 00:06:15,800
if you go with any programming or scripting language, if it

106
00:06:15,800 --> 00:06:19,100
supports functional as well as OOPS concept, then definitely

107
00:06:19,100 --> 00:06:24,900
it is a good language. Python is also one of that, right. Fine.

108
00:06:25,500 --> 00:06:28,700
Now coming to our course structure,

109
00:06:29,100 --> 00:06:31,700
I mean this entire course what we are going to learn and

110
00:06:31,700 --> 00:06:38,000
what is the sequence we are going to learn Python, see first

111
00:06:38,000 --> 00:06:41,200
we are going to cover Core Python. In Core Python

112
00:06:41,200 --> 00:06:45,000
I am going to cover basics of Python modules, libraries, packages,

113
00:06:45,000 --> 00:06:48,600
and functions, and then I will go and work with your OOPS

114
00:06:48,600 --> 00:06:52,100
concept. So this is my course structure guys.

115
00:06:52,900 --> 00:06:56,700
So finally just I want to give the information about your

116
00:06:56,900 --> 00:06:58,100
Python. Simply

117
00:06:58,400 --> 00:07:03,400
what is Python. Python is a powerful multi-purpose or general

118
00:07:03,400 --> 00:07:07,400
purpose programming language, and created by Guido Van Rossum.

119
00:07:08,600 --> 00:07:12,600
Multi-purpose or general purpose programming, that means Python

120
00:07:12,600 --> 00:07:14,700
you can use it in anywhere in your real time.

121
00:07:15,900 --> 00:07:19,100
Simply you can use your Python anywhere in your real time.

122
00:07:19,600 --> 00:07:20,600
That's it.

123
00:07:21,200 --> 00:07:23,800
And not only with your Python if you go with any software

124
00:07:23,800 --> 00:07:26,400
generally there are different versions. Even in Python

125
00:07:26,400 --> 00:07:28,800
also we have two types of versions.

126
00:07:28,800 --> 00:07:33,500
They are 2.x and 3.x. Again in 2.x

127
00:07:33,500 --> 00:07:36,200
and 3.x we have some sub-versions, but you don't

128
00:07:36,200 --> 00:07:37,900
bother about sub-versions, right?

129
00:07:38,700 --> 00:07:44,900
It's very simple to understand. And comparing to 2.x and

130
00:07:44,900 --> 00:07:51,100
3.x, right, in 3.x most of the outputs are like objects.

131
00:07:51,100 --> 00:07:53,500
[no audio]

132
00:07:53,500 --> 00:07:55,900
but in 2.x directly we'll get your output.

133
00:07:57,400 --> 00:08:00,700
So actually enhanced technique is there with your 3.x.

134
00:08:02,300 --> 00:08:03,400
Anyway, one more thing

135
00:08:03,400 --> 00:08:06,200
you have to remember, after 2020

136
00:08:06,200 --> 00:08:10,200
there will be no further new development with 3.x,

137
00:08:10,200 --> 00:08:11,300
sorry 2.x.

138
00:08:12,500 --> 00:08:17,300
After 2020 there will be no further development with 2.x.

139
00:08:18,000 --> 00:08:22,700
So that's why definitely after 2020, right, all of the organizations

140
00:08:22,700 --> 00:08:26,500
they are going to move with 3.x, and again in 3.x

141
00:08:26,500 --> 00:08:31,300
you have 3.4, 5, 6, and 7. Now the latest version with your

142
00:08:31,300 --> 00:08:33,700
3.x is 3.7.x.

143
00:08:35,100 --> 00:08:39,900
Now, it's better to learn 3.7.x. It may be any version, 3.7.1

144
00:08:39,900 --> 00:08:44,000
or 3.7.2 or 3 or 4, something like that, right?

145
00:08:44,100 --> 00:08:49,400
So here as of now, I am going to take the stable version in 3.x,

146
00:08:49,400 --> 00:08:51,000
that is 3.7.0.

147
00:08:52,000 --> 00:08:56,200
Right. So this entire course I am going to explain with the 3.7.0.

148
00:08:56,600 --> 00:08:59,400
But whatever the syntax is we are using while explaining

149
00:08:59,400 --> 00:09:04,200
your 3.7.0 same syntaxes you can use with your 3.x

150
00:09:04,200 --> 00:09:05,900
versions, right?

151
00:09:06,200 --> 00:09:10,300
My intention is, it's better to learn 3.x because

152
00:09:10,400 --> 00:09:16,200
we are very near to 2020 so, after that definitely, right, major

153
00:09:17,300 --> 00:09:20,100
development, major third-party modules will come with

154
00:09:20,100 --> 00:09:22,300
3.x only, right.

155
00:09:22,300 --> 00:09:26,200
So that's the reason I am starting the 3.x version Python training.

156
00:09:27,600 --> 00:09:28,900
Right. Okay guys,

157
00:09:28,900 --> 00:09:30,300
thank you for watching this video.

158
00:09:30,300 --> 00:09:37,600
[no audio]
