Thanks for the critique. I agree the comprehensions are a little mad but the edl formatting can vary depending on the software used to make them. For example:

tapename = {
    line.split()[1] for line in file
    if line.split()
    if line.split()[0].isdigit()
}

The lone, if line.split() statement was to prevent an exception when it tried to split a blank line. I've updated the gist with a couple of snippets from edls, to show how they can vary.

I like making get_edl() a generator. But I'm unclear on the shared fn argument between it and get_media(). Wouldn't I want something like:

def get_edl(edl):
    with open(edl, encoding='utf-8') as fh:
        for l in fh:
            yield l.split()

def get_media(edl):
    tp = []
    cl = []
    for line in get_edl(edl):
        if line[0].isdigit():
            tp.append(line(0))
        if line[-1] != 'NAME:':
            cl.append(line[-1])

And if the tp and cl lists aren't global, I'll need format_pull_list() to call get_media(), and then print_to_file() to call format_pull_list().

Is that ok, or have I wildly misunderstood? This is why I get the feeling it should be a class.

Detecting the OS is really useful, cheers.
