Sometimes it can be interesting to know how many lines of Python code have you written for a project, or in total. So i've written this Python script that counts lines of code in *.py of a directory recursively.
import os
def linescounter(dir, lines=0, header=True, begin_dir=None):
if header:
print('{:>7} |{:>7} | {:<20}'.format('Lines', 'Total', 'File'))
print('{:->8}|{:->8}|{:->20}'.format('', '', ''))
for item in os.listdir(dir):
item = os.path.join(dir, item)
