So can I ask what happens internally in python when you create open a file object in a loop without assigning that file object to a variable?
E.g.: for line in open(file.py): print line In the above, is pythonimplicitly creating a reference to a file object and using that in the for loop? Or is something else going on under the hood? Either way, I figured that if you don't assign the file object to a variable, then the file object is trashed by python's garbage collection once the loop reaches end-of-file. Is the above a correct understanding?
