2
00:00:02,200 --> 00:00:03,700
Friends, here we are going to

3
00:00:03,700 --> 00:00:06,100
write one simple Python Script. That is,

4
00:00:07,100 --> 00:00:13,200
read a path and check if given path is a file or a directory.

5
00:00:13,600 --> 00:00:16,900
So you have to write one Python Script such that it has to

6
00:00:16,900 --> 00:00:19,600
read some path. After providing path,

7
00:00:20,100 --> 00:00:24,700
right, your python has to validate that, whether the given path is

8
00:00:24,700 --> 00:00:28,810
for file or is for directory, right. Fine.

9
00:00:28,800 --> 00:00:31,000
Let me open my editor first.

10
00:00:31,900 --> 00:00:36,700
So guys, we know if you want to read a path, path is always

11
00:00:36,700 --> 00:00:39,900
a string you need to remember that. Path is always a string.

12
00:00:39,900 --> 00:00:43,200
If you go with any operating system path is always a string.

13
00:00:43,900 --> 00:00:48,100
First let me save program as 'identify_given_path',

14
00:00:48,100 --> 00:00:49,400
or 'working_on_path'.

15
00:00:49,400 --> 00:00:52,210
[no audio]

16
00:00:52,200 --> 00:00:57,100
Let me take something like 'path_file_directory.py'.

17
00:00:58,200 --> 00:01:03,300
Fine. See my intention is, I want to read a path first. So path is

18
00:01:03,300 --> 00:01:04,000
always a string.

19
00:01:04,000 --> 00:01:06,110
That's why you know in your Python

20
00:01:06,099 --> 00:01:12,400
you have a 'input' syntax to read any string. Now I am taking

21
00:01:12,400 --> 00:01:16,200
variable as 'path', and I'm asking the user "Enter your path: ".

22
00:01:16,200 --> 00:01:19,710
[no audio]

23
00:01:19,700 --> 00:01:22,100
Right. So after that what I have to do?

24
00:01:23,100 --> 00:01:25,700
Whatever the path you are providing that path

25
00:01:25,700 --> 00:01:30,200
I have to check whether it is a file or directory path. Then

26
00:01:30,200 --> 00:01:34,310
how can I validate that? See, previously we discussed somewhere

27
00:01:34,300 --> 00:01:40,500
your 'os.path' sub-module of your 'os'. 'os.path.isfile()'

28
00:01:40,500 --> 00:01:43,300
'isdirectory'. You can go with anyone of that.

29
00:01:43,700 --> 00:01:46,410
So now I want to use 'os' module,

30
00:01:46,400 --> 00:01:48,400
that's why first you need to import your 'os',

31
00:01:48,400 --> 00:01:50,400
[no audio]

32
00:01:50,400 --> 00:01:53,000
then whatever the 'path' you are providing

33
00:01:53,000 --> 00:01:54,400
I'm checking with 'if' condition.

34
00:01:54,400 --> 00:01:57,600
'if os.path.isfile',

35
00:01:57,600 --> 00:02:01,500
that means if given path is a file then this will become

36
00:02:01,500 --> 00:02:04,800
'True'. If it is 'True', then whatever the logic you are going

37
00:02:04,800 --> 00:02:08,000
to write under your 'if' condition that will execute. Now what

38
00:02:08,000 --> 00:02:08,900
I want to display?

39
00:02:08,900 --> 00:02:11,810
[no audio]

40
00:02:11,800 --> 00:02:12,800
"The given

41
00:02:15,100 --> 00:02:17,200
path: ", whatever the path is there.

42
00:02:17,200 --> 00:02:19,609
[no audio]

43
00:02:19,600 --> 00:02:24,810
Sorry, "is a file". That's it.

44
00:02:24,800 --> 00:02:29,900
So in case if given path, given path is not a file, then this

45
00:02:29,900 --> 00:02:31,600
condition will become 'False'.

46
00:02:33,100 --> 00:02:34,609
That means that is not a file.

47
00:02:34,600 --> 00:02:37,510
If that is not a file, then what is our option?

48
00:02:37,500 --> 00:02:39,500
Definitely, it is a directory, right. Then

49
00:02:39,500 --> 00:02:41,000
let me do it, 'else' block

50
00:02:41,000 --> 00:02:42,100
I am writing, 'print("

51
00:02:43,800 --> 00:02:49,700
The given path :", whatever the path you are providing that is,

52
00:02:50,700 --> 00:02:54,310
"is a directory path". That's it.

53
00:02:54,300 --> 00:02:55,300
Let me save it.

54
00:02:56,000 --> 00:02:57,600
Now I want to run this.

55
00:02:57,600 --> 00:02:59,000
So let me open my command line.

56
00:02:59,000 --> 00:03:00,800
[no audio]

57
00:03:00,800 --> 00:03:04,600
So already I am in the location where you have your script, this one.

58
00:03:04,600 --> 00:03:06,600
Let me run it with your 'python3'.

59
00:03:07,400 --> 00:03:09,800
I am working with Python 3 only guys. Sorry.

60
00:03:10,300 --> 00:03:13,300
'python --'

61
00:03:13,300 --> 00:03:15,600
[no audio]

62
00:03:15,600 --> 00:03:17,500
Let me do simply this thing. Yeah.

63
00:03:17,900 --> 00:03:22,704
Now let me run your script, that is,
'path_file_dir.py'

64
00:03:23,300 --> 00:03:24,700
Yes, it is asking something.

65
00:03:25,100 --> 00:03:29,300
So guys, we are working on Windows, right. See whenever you

66
00:03:29,300 --> 00:03:33,300
if you are working with Windows you always, you have to always

67
00:03:33,300 --> 00:03:37,100
provide your path as, I mean while entering your path you

68
00:03:37,100 --> 00:03:41,510
have to provide '\\' in your path instead of '\'.

69
00:03:41,500 --> 00:03:43,200
You know what is the reason. We already discussed that in

70
00:03:43,200 --> 00:03:44,609
our previous sessions.

71
00:03:44,600 --> 00:03:50,100
Now let me enter it and see the output. "The given path : ", "is a directory".

72
00:03:50,100 --> 00:03:51,910
Yes, you are getting the thing.

73
00:03:51,900 --> 00:03:55,200
Now, let me rerun and I am providing same thing,

74
00:03:55,200 --> 00:03:58,800
but at the end I am giving our Python Script name itself, no problem.

75
00:03:58,800 --> 00:03:59,800
You can provide anything.

76
00:03:59,800 --> 00:04:01,700
[no audio]

77
00:04:01,700 --> 00:04:06,600
Now see the result what you are getting, "is a file". Right. Now

78
00:04:07,900 --> 00:04:08,900
let me rerun,

79
00:04:10,300 --> 00:04:12,000
and I am giving something called,

80
00:04:13,000 --> 00:04:14,900
some "x:

81
00:04:14,900 --> 00:04:18,800
[no audio]

82
00:04:18,899 --> 00:04:22,500
\\python". So this path I am giving, but output you're getting,

83
00:04:22,500 --> 00:04:23,500
"is a directory".

84
00:04:24,000 --> 00:04:27,399
But if you observe, this path is not there in my host. If you

85
00:04:27,399 --> 00:04:32,800
go with my system, see that I have only C, E, and F, G directories.

86
00:04:32,800 --> 00:04:35,700
I don't have this directory no, 'X'. 'X' Drive

87
00:04:35,700 --> 00:04:38,400
I don't have but still you are getting information as "is a directory".

88
00:04:39,000 --> 00:04:41,900
It's absolutely wrong. Why you are getting this situation

89
00:04:41,900 --> 00:04:46,900
means, you are checking if given thing is a file,

90
00:04:46,900 --> 00:04:47,900
then you are executing this.

91
00:04:48,600 --> 00:04:53,100
So whether it is a directory or if it is invalid then at

92
00:04:53,100 --> 00:04:56,500
that time by default this result would become 'False', at that

93
00:04:56,500 --> 00:04:57,710
time you're executing 'else'.

94
00:04:57,700 --> 00:05:01,300
That's why what I have to do is before checking whether that

95
00:05:01,300 --> 00:05:02,700
is a file or directory,

96
00:05:02,700 --> 00:05:05,800
first of all you have to check whether that given path is

97
00:05:05,800 --> 00:05:06,800
existing or not.

98
00:05:07,900 --> 00:05:11,800
Right. See that's why what I am doing is, let me delete your entire code.

99
00:05:11,800 --> 00:05:18,300
[no audio]

100
00:05:18,300 --> 00:05:23,500
Now what I am doing is, 'if os.path.exist',

101
00:05:24,900 --> 00:05:28,300
if a given path is existing, then only I want to identify

102
00:05:28,300 --> 00:05:29,610
whether that is a file or not.

103
00:05:29,600 --> 00:05:31,300
If it is not existing I don't want to do it.

104
00:05:31,300 --> 00:05:33,300
[no audio]

105
00:05:33,300 --> 00:05:36,500
Right. Fine. Now I am saying simply.

106
00:05:37,700 --> 00:05:39,000
"Given path is valid".

107
00:05:39,000 --> 00:05:41,200
[no audio]

108
00:05:41,200 --> 00:05:44,000
If it is valid then only I can identify whether it is a

109
00:05:44,000 --> 00:05:47,700
file or not, 'else: print()'.

110
00:05:47,700 --> 00:05:51,510
[no audio]

111
00:05:51,500 --> 00:05:55,300
"Given path", so if you want to write that path you can write

112
00:05:55,300 --> 00:05:59,900
it, right, "is not existing on this host".

113
00:05:59,900 --> 00:06:02,310
[no audio]

114
00:06:02,300 --> 00:06:03,300
That's it.

115
00:06:03,300 --> 00:06:05,200
[no audio]

116
00:06:05,200 --> 00:06:07,600
"Given path", whatever the path you are giving let me write

117
00:06:07,600 --> 00:06:10,000
that path, "is a valid" one,

118
00:06:10,000 --> 00:06:13,300
first thing, is a valid path. First

119
00:06:13,300 --> 00:06:16,600
let me run this, then we will add your code.

120
00:06:16,600 --> 00:06:20,010
[no audio]

121
00:06:20,000 --> 00:06:22,900
Not. Let me go to command line.

122
00:06:22,900 --> 00:06:24,000
Let me run it.

123
00:06:24,000 --> 00:06:26,300
I'm running and I am providing, before running

124
00:06:26,300 --> 00:06:27,200
let me do this thing.

125
00:06:27,200 --> 00:06:29,710
[no audio]

126
00:06:29,700 --> 00:06:30,810
This is your code.

127
00:06:30,800 --> 00:06:36,300
Now, I'm running, and I'm going to provide some random thing, see

128
00:06:36,300 --> 00:06:38,100
"x: is not existing on this host".

129
00:06:38,100 --> 00:06:39,400
Actually, that is not a valid path

130
00:06:39,400 --> 00:06:42,610
that's why we are getting, that is not existing on this path.

131
00:06:42,600 --> 00:06:45,610
Now, let me rerun and provide some valid path.

132
00:06:45,600 --> 00:06:47,900
See this is a valid path, right. Whether it is a file or not

133
00:06:47,900 --> 00:06:51,100
secondary. First of all, I am checking whether that is existing

134
00:06:51,100 --> 00:06:52,100
on your host or not.

135
00:06:53,000 --> 00:06:54,000
That's what you're doing here.

136
00:06:54,000 --> 00:06:55,600
'os.path.exists'.

137
00:06:56,500 --> 00:07:02,300
See that. "Given path is valid path", even if you provide directory

138
00:07:02,300 --> 00:07:05,900
also, it will work. See up to this, this is a directory path,

139
00:07:05,900 --> 00:07:12,409
right. It's working. So after verifying that is a valid path,

140
00:07:12,400 --> 00:07:14,700
right, after that you have to check whether that is a directory

141
00:07:14,700 --> 00:07:18,100
or not. That's why inside of your 'if' condition you have to

142
00:07:18,100 --> 00:07:24,600
write one more 'if' condition, that is 'if os.path.isfile,

143
00:07:25,000 --> 00:07:27,900
then, then I can write 'print

144
00:07:29,500 --> 00:07:31,500
("Given path : "', whatever the

145
00:07:31,500 --> 00:07:35,000
path is there simply I will write, and "it is a",

146
00:07:35,000 --> 00:07:37,600
[no audio]

147
00:07:37,600 --> 00:07:38,600
and "it is a

148
00:07:39,700 --> 00:07:41,000
file path",

149
00:07:42,700 --> 00:07:44,700
'else:'. 'else:'

150
00:07:45,000 --> 00:07:49,600
See first of all, after existence of your path you are entering

151
00:07:49,600 --> 00:07:53,200
into this block, inside of that your 'if' condition once again,

152
00:07:53,200 --> 00:07:55,600
we are verifying whether that is a file or not with your

153
00:07:55,600 --> 00:07:58,700
'os.path.isfile'. 'isfile',

154
00:07:58,700 --> 00:07:59,700
this will become 'true',

155
00:07:59,700 --> 00:08:02,100
then you are printing, "and it is a file path".

156
00:08:02,100 --> 00:08:07,400
If it is not, then what you are displaying, "and it is a directory

157
00:08:08,900 --> 00:08:09,900
path". That's it.

158
00:08:11,300 --> 00:08:13,500
Right. See that. I am going to run,

159
00:08:13,500 --> 00:08:15,460
[no audio]

160
00:08:15,450 --> 00:08:19,300
and I'm going to provide. See that. "valid path", and "it is a

161
00:08:19,300 --> 00:08:25,300
directory". Right. Then rerun and provide some file path.

162
00:08:25,400 --> 00:08:28,800
Yes. First of all, it "is a valid path", "and it is a file path".

163
00:08:28,800 --> 00:08:29,800
That's it.

164
00:08:30,700 --> 00:08:32,299
Right. So guys, this is the way

165
00:08:32,299 --> 00:08:35,799
simply how you can verify given path is

166
00:08:35,700 --> 00:08:38,200
a file path or directory path.

167
00:08:38,700 --> 00:08:43,700
So make sure that before validating your path is a file or directory path

168
00:08:43,799 --> 00:08:45,200
first of all you should check it,

169
00:08:45,200 --> 00:08:48,299
you should verify it whether that given path is existing

170
00:08:48,299 --> 00:08:49,299
on your host or not.

171
00:08:50,700 --> 00:08:53,900
If it is not existing, then you can't identify whether it

172
00:08:53,900 --> 00:08:55,000
is a file or directory.

173
00:08:55,000 --> 00:08:57,010
[no audio]

174
00:08:57,000 --> 00:08:58,100
Right. Fine.

175
00:08:58,800 --> 00:09:02,800
