Starting to learn python

on Dec 13, 2015

Just started to learn python. I know general programming concepts, but not Python specifically or its syntax, so this was new for me. I love it. Coolest thing? for line in file: This is so great.

Anyways, I made a python script, that when run, creates a copy of itself in the same directory. I think it's pretty cool.

import os
import binascii

def replicate(path):
    # Replicate a file given the path of the current file.  Opens current file
    # and new file and reads all lines into new file.
    with open(get_new_filename(path), "w") as newfile, open(path) as program:
        for line in program:

def get_new_filename(old_name):
    # Gets a new filename given a filename to work off of.  Splits the old name
    # by periods, then adds a random hex string right before the filetype
    # ending.  Given 'files.py', a valid output would be 'files-2b57f5.py'.
    # The function also checks for collisions and adds another random string to
    # the end if necessary.
    # http://stackoverflow.com/a/2782293
    broken_name = old_name.split('.')
    while True:
        ending = '-' + str(binascii.b2a_hex(os.urandom(3))).replace('\'', '')
        broken_name[-2] = broken_name[-2] + ending
        name = '.'.join(broken_name)
        if not os.path.exists(name):
    return name

if __name__ == '__main__':

I want to do something with my new knowledge, but I don't know what. I think an entire os made of python would be pretty cool, but my skills are definitely not at the level, and python might be too high level and slow.

That is actually what it feels like, no joke.
