get print() output

[Skaperen]

the function is written under normal filesystem assumptions it can be given a file name and will open it or be given an already open file object.  in both cases it closes it when done writing.  i have been giving it a filesystem file and when the function returns, open the file for reading and reading it.

i think what it does is:

def function(...,file=None):
    try:
        o=open(file.fileno(),'w')
    except whatever:
        try:
            o=open(file,'w')
        except whatever:
            o=sys.stdout
    ...
    print(stuff.file=o) # many places
    ...
    o.close()
    return

or something similar like holding options in a dictionary.

it's a rather normal thing to close a file when done with it.
