Why type(int_int) will be int in python?

Question

I find a weird thing in Python, if I assign a variable as int_int, float_int, int_float, the type will be int, float, float, seems the underline is a join character, like:

x = 100_200

then x will be a int, value is 100200. Can someone explain why and how to reasonable use?

Python 3.6 introduced Underscores in Numeric Literals.

Essentially, this is a readability feature.

Compare:

x = 100000000

and:

x = 100_000_000

The DV might also have been before you edited the example in, so it was a link-only answer. Or maybe they thought you should have tried harder to find a dup before answering. – Barmar May 24 '18 at 01:40
