Code:
open('rb')

function within a context manager (

Code:
with

keyword) and read its content into a string variable using

Code:
f.readlines()

. You can then convert the string to a CSV using various approaches such as the

Code:
csv

module.

Code:
'my_file.man'

into your Python script:

with open('my_file.man', 'rb') as f: content = f.readlines() print(content)

Code:
open()

function opens a text file. If you want to open a binary file, you need to add the

Code:
'b'

character to the optional

Code:
mode

string argument.
