Python - How to read files in multiple ways

Read file all in one shot

with open(filepath, 'r') as file:
    data = file.read()

Above code read whole file at once, but if the files have multiple lines, the result string will have new line characters as well.

This code will gets you a single string as whole content

Read file all in one shot and remove newline character

with open(filepath, 'r') as file:
    data = file.read().replace('\n', '')

This code will gets you a single string as whole content

Read all content at once into list of lies

with open('filename') as f:
    lines = f.readlines()

Again, this will give new line characters

Read all content at once into list of files and remove newline character

with open('filename') as f:
    lines = [line.rstrip() for line in f]

Another way to read file at once into list of words and remove newline character

with open(source_file) as f:
    lines = f.read().splitlines()

The best way to open file is with with keyword, as you do not need to close the file explicitly. It will take care of closing the file handle.
