SyntaxError: invalid syntax

I followed the instruction but getting the above error when trying to run the command on my repository.

Are you using a python version lower than 3.6?

I do not write much python, but I found out these f-strings were introduced in python 3.6

https://docs.python.org/3/whatsnew/3.6.html#pep-498-formatted-string-literals

I modified the code using a string interpolation feature with broader support, and it worked

Use python version 3.8 or higher and it will work. If you're copying the file manually make sure it's copied correctly as there are long lines that a basic text editor like nano might not handle well.
