Please help with my python code!

Question

https://code.sololearn.com/cdpkTv44Xuh6

This is not finished, but how can I even make this work?
Like I want to be able to insert 1 and then it will call the function I want to execute.

Answer 1

But when I try to call the function Numerical_Strings, it won't call it because I haven't called it. I want it to be so that I don't have to call every single function in my program. Is it possible?

Answer 2

To call a function after you entered 1 works

Answer 3

You need to put the function definition *before* the function call.
