Python to Pseudocode converter

'''
INSTRUCTIONS
1. Create a file with the following code
2. Put the file you want to convert into the same folder as it, and rename it to "py_file.py"
3. Add a "#F" comment to any lines in the code which have a function call that doesn't assign anything (so no =),
as the program cannot handle these convincingly
4. Run the converter file

@BlueNexus I tried this and made sure everything is in the same folder and same name. There is no output.
