How to read a file line-by-line in python?

Reading files line-by-line is a common operation when working with text files.

Example:

  with open('file.txt', 'r') as file:
      for line in file:
          print(line)
  

Solution:

Using the with statement ensures that the file is properly closed after it's read. Iterating over the file object directly allows you to read the file line by line.
