How to get the number of digits in a number?

You can do it “mathematical way”. If you take log10 from absolute value of number and round result up, then you get number of digits in a number (except for cases of 0 and 1). You can round up or round down, it will just alter origin of exponent. Note that it uses log10 and other math functions, so it might be slower than using strings.

What is the correct indentation for Python?

Python programs use white space at the beginning of a line to define scope, such as a block of code.
