Hi Emile,
Question: What is the source of the line 7 syntax: mbox.split?
I read mbox from the file. eg,
mbox = open("mbox-short.txt",'r').read()
and it looks to me that if you insert the above in front of the for loop
below you'll get further.

It's perfectly legal and ok to say:
###
def main():
callHelper()
def callHelper():
print("I am the helper")
All your function definitions should be defined with 'def' at the
leftmost margin.
However, the line in your program that starts with "def
open_existing_file()..." is not flush with the margin. Python has,
subsequently, thought that the definition of the function is scoped
locally. Move the begi
