File I/O in Python: looping over the file handle (it's an iterable!)
The easiest way to read a text file is by looping over the file handle itself, that's actually an iterable (like a list). The loop variable is then assigned the contents of the file, one line at a time. In this video, I demonstrate this technique using a simple text file. Be aware that the newline character at the end of the line also gets read, and you'll normally want to strip it away from your string. Check out the notebooks linked below for more information on file handling in Python.
