Output:

Who

1. The naming of your functions isn't great - what do "1" and "2" mean?
2. You shouldn't need to write your own max function anyway, since the standard library has one.
3. input already returns a string, so the calls to str on lines 1-3 are redundant.

Your code does not work for numbers. If you type numbers when asked to "insert text" it will sort the "numbers" alphabetically instead of numerically because the "numbers" are strings. For example, the numbers 3, 22, 111 would be sorted to be in order 111, 22, 3 because '1' < '2' < '3'.

I've been writing Python code for about a year and I still write code very badly.

I still don't understand your comment about "but can't work with numbers". What does did you mean by that? Is that a problem where you would like to receive some help? If so, please provide additional information.

Your code is small and very pretty, but you get an error when adding numbers. My code summarizes numbers and text, it would be better if they made it universal.
my code shows how python uses the function in the function, it understands the parameters regardless of their number
