Thanks man. Just spent an hour and a half banging my head against the wall trying to convert a string element ("3.0") of a mixed list to an int, but was inexplicably getting a dreaded error, until I discovered your tutorial.

string = "Doc. Version 3.0"

mylist = string.split()

alphanum = (mylist[2])

alphanum = int(alphanum) # Thought this would do it, but nah.

print(alphanum)

Sad output:
Traceback (most recent call last):
File "D:\Programming\Python\Python_scripts\thonny_practice_scripts\string_to_int_check.py", line 6, in <module>
alphanum = int(alphanum)
ValueError: invalid literal for int() with base 10: '3.0'

Turns out all I had to do was use a float as you suggested:

alphanum = float(alphanum)

Output: 3.0

Voila!

type(alphanum)
<class 'float'>
("3.0")

Never even considered that the document version number was a float! I just thought of it as version 3.
