Ian, take a step back; the first step to solve a problem is to state it
clearly. You want to write a dict to a file.
(1) What would the dictionary look like? Give concrete example, e. g.
{"foo": 42, "bar": 'that\'s not "funny"'}
(2) What should the resulting file look like when you open it in a

None of the above unless you need to keep the original list1. Use
event code from being executed on import by adding

Example:
$ cat hello.py
def hello(name):
print("Hello, {}".format(name))
if __name__ == "__main__":
