Remove Blank Lines from a File with Python

Hi everyone! After fighting with syntax errors for the last ten minutes, I've finally figured out an elegant one-liner that removes all blank lines from a Python file.

with open('your_file.txt') as file:  lines = list(filter(lambda l: l.strip(), file.readlines()))  for line in lines:    print(line)

I had already been told that the strip() method was the way to go when determining blank lines, so I simply incorporated it into a lambda function. Best part in my opinion - it doesn't mutate the original file because it uses filter.
