My program is almost complete but I can't seem to allow the...
"Would you like to do more calculations? Enter (Y) for yes, or any ""other character for no. "
...output from going through without first entering my selection (e.g. "Y" or any other character") numerous times.
I would really appreciate some help!

If this is really your first program, that's truly impressive!
So, I've pasted the code we want to focus on below:
restart_msg = input("Would you like to do more calculations? Enter (Y) for yes, or any other character for no. ")
if not restart(str(input(restart_msg))): # uses the function I wrote
return # Stop the program
In the first line, the computer prompts for an input with "Would you like to do more calculations?" (and so on). It then stores that first input in the variable restart_msg. Then, in the second line, you call restart(str(input(restart_msg))). Since that contains a call to input() and passes restart_msg as the only parameter, the computer prompts for an input by outputting whatever you just entered. It stores that entry in a string, and passes it to restart().
It seems like this is your intention in the second line:
if not restart(str(restart_msg)):
That way, the computer converts the first input you entered to a string by passing it through str(), and passes that through your restart function.
This is a pretty ambitious project, good luck!
