1
00:00:00,660 --> 00:00:02,560
File Matthau's in Biton.

2
00:00:03,150 --> 00:00:05,460
So there are so many different methods out there.

3
00:00:05,820 --> 00:00:08,580
And depending upon the input argument, variation.

4
00:00:08,910 --> 00:00:10,500
Different methods are the same.

5
00:00:10,500 --> 00:00:13,350
Methods may have different implications.

6
00:00:13,710 --> 00:00:19,020
So here in this video, we shall be discussing different file methods in Python.

7
00:00:20,210 --> 00:00:22,360
So here we are having some list of.

8
00:00:22,880 --> 00:00:24,770
So let me discuss some of them at least.

9
00:00:25,220 --> 00:00:30,230
So this is the method name and there is a description so close, close and open.

10
00:00:30,230 --> 00:00:30,670
Fine.

11
00:00:31,070 --> 00:00:34,880
And it has no effect if the file is already closed.

12
00:00:35,540 --> 00:00:36,890
Detach separate.

13
00:00:36,890 --> 00:00:42,410
The underlying binary buffer from the text are your best and return it.

14
00:00:43,010 --> 00:00:45,200
Next one is a file, a no return.

15
00:00:45,200 --> 00:00:46,540
An indigent no.

16
00:00:46,730 --> 00:00:49,340
There is a file descriptor of the file.

17
00:00:49,670 --> 00:00:52,060
So each and every file we need to get append.

18
00:00:52,460 --> 00:00:56,470
Then it will be accessed with some file descriptor number.

19
00:00:56,690 --> 00:00:58,130
So that number will be returned.

20
00:00:58,340 --> 00:01:01,790
So using this method file in all that is a file number.

21
00:01:02,100 --> 00:01:06,290
We're having this flash floods, the right buffer of the file stream.

22
00:01:06,470 --> 00:01:09,590
So what about what characters are there in the in the buffer.

23
00:01:09,590 --> 00:01:09,800
Right.

24
00:01:09,800 --> 00:01:10,160
Buffer.

25
00:01:10,310 --> 00:01:11,330
So they'll be cleared.

26
00:01:11,840 --> 00:01:14,120
Our next one is there is a two way.

27
00:01:14,480 --> 00:01:18,110
So it returns to the file stream is interactive.

28
00:01:18,740 --> 00:01:22,820
So read n read at most in characters from the file.

29
00:01:23,210 --> 00:01:25,310
Read till end of the file.

30
00:01:25,430 --> 00:01:27,760
If it is a niggly or none.

31
00:01:28,280 --> 00:01:29,540
We're having this readable.

32
00:01:29,750 --> 00:01:33,320
So returns true if the file stream can be read from.

33
00:01:33,380 --> 00:01:34,310
So that is a readable.

34
00:01:34,550 --> 00:01:36,400
Will be returning boolean.

35
00:01:36,560 --> 00:01:39,080
So either it will return true or false.

36
00:01:39,530 --> 00:01:42,260
So read line in is equal to minus one.

37
00:01:42,620 --> 00:01:48,560
So read and return one line from the file and reads in that most invites.

38
00:01:49,070 --> 00:01:50,330
If specified.

39
00:01:50,570 --> 00:01:52,000
So that is the invites are there.

40
00:01:52,360 --> 00:01:53,810
And this minus one is there.

41
00:01:54,080 --> 00:02:00,700
So read and return one line from the file and read at a reading at most invites.

42
00:02:01,280 --> 00:02:04,340
And if the N is specified in the parameter.

43
00:02:06,280 --> 00:02:09,220
We're having these red lines, but invisible to minus one.

44
00:02:09,550 --> 00:02:16,320
So read and return a list of lines from the file and read in at most invites our characters.

45
00:02:16,660 --> 00:02:23,470
If specified, then we're having this sick offset from is the girl to sick underscore set.

46
00:02:23,830 --> 00:02:31,600
So change the file perdition to offset bias in different to from that is a start current and end.

47
00:02:31,840 --> 00:02:37,900
So there is a file pointer will have some movement will have some progress depending upon the parameters.

48
00:02:37,960 --> 00:02:39,020
What about are past.

49
00:02:39,700 --> 00:02:40,820
Next one is a sequel.

50
00:02:41,080 --> 00:02:45,220
Returns true if the file stream supports random access.

51
00:02:45,370 --> 00:02:50,140
So if you can't go for the random accessing of the file content then need to return the output.

52
00:02:50,140 --> 00:02:50,370
True.

53
00:02:50,530 --> 00:02:51,850
So it returns boolean.

54
00:02:52,300 --> 00:02:55,840
So next one is a till he returns the current file location.

55
00:02:56,020 --> 00:02:59,890
So what is the where is the respective file point location to which location.

56
00:02:59,920 --> 00:03:03,310
It is pointing to the current location will be returned here.

57
00:03:03,760 --> 00:03:06,130
TRUNCATE site is equal to N one.

58
00:03:06,340 --> 00:03:09,180
So this is the file stream, two site bytes.

59
00:03:09,490 --> 00:03:14,230
And if the site is not specified, research to current location.

60
00:03:14,570 --> 00:03:16,510
We're having this rateable returns.

61
00:03:16,510 --> 00:03:19,420
True if the files team can be written to.

62
00:03:19,630 --> 00:03:24,430
So in the so you are having different functions that are methods that you can easily pause the video

63
00:03:24,640 --> 00:03:25,570
and go through them.

64
00:03:25,990 --> 00:03:29,370
And obviously we shall we shall write some calls on them.

65
00:03:31,470 --> 00:03:37,430
So here to see if previously we had red lines, so here that were in that case, we had ended the goal

66
00:03:37,440 --> 00:03:40,350
to minus one, but here you see in is again two point one.

67
00:03:40,590 --> 00:03:42,270
So what are their respective changes?

68
00:03:42,480 --> 00:03:45,630
They're having almost the same methods, the same method lists are there.

69
00:03:45,960 --> 00:03:48,770
But the input parameters are getting deferred.

70
00:03:48,990 --> 00:03:51,330
So what does that changes, respectively?

71
00:03:51,630 --> 00:03:57,650
That has been depicted in this method and that description column Bill returns the current file Lukash

72
00:03:57,660 --> 00:04:03,540
on, say, December, because we're not passing any parameter to that truncate scientifical two in one.

73
00:04:03,720 --> 00:04:06,560
So this saves the file stream to site bytes.

74
00:04:06,840 --> 00:04:11,400
If the site is not specified, it S.H. to the current location.

75
00:04:11,730 --> 00:04:17,050
So in this way, in this video, we Becka's different file methods available in bipartite.

76
00:04:17,610 --> 00:04:18,840
Thanks for watching this video.
