Python's file.readlines(~) method returns a list containing each line in the file as a list item.
Parameters
1. sizehint | number | optional
The number of bytes to read up until. Default is to read whole file.
Return value
List containing each line in the file as a list item.
Examples
To return a list containing each line from test.txt file as a list item:
f = open("test.txt", "r")print(f.readlines())
['sample line 1\n', 'sample line 2\n', 'sample line 3\n', 'sample line 4\n']
NOTE
By default the newline character (\n) is included at the end of each string element in the list.
To remove the newline character we can use the str.rstrip(~) method:
f = open("test.txt", "r")content = (f.readlines())
content = [x.rstrip() for x in content]print(content)
['sample line 1', 'sample line 2', 'sample line 3', 'sample line 4']
