glittershark / terrible.py
Created November 1, 2013 00:53
Intentionally terrible script made for an interview. The subject is asked to fix the script up, and add the functionality for the user to specify a specific file extension to copy.
import os
for index_variable in range(len(os.listdir('.'))):
if os.listdir('.')[index_variable][os.listdir('.')[index_variable].find('.'):] == '.txt':
print "found text file"
import shutil
import sys
shutil.copyfile('./' + os.listdir('.')[index_variable], sys.argv[1] + '/' + os.listdir('.')[index_variable])
for i in range(len(sys.argv) - 2):
if sys.argv[i + 2] == '--and':
shutil.copyfile('.' + os.listdir('.')[index_variable], sys.argv[i + 3])
