Introduction

When I used a random number for the first time in Python, there was a similar notation, so I wrote the difference.

What is randrange ()

random.randrange (a, b) returns an integer from "a" to "b-1". If there is one argument, an integer with an argument minus 1 is returned from "0".

What is random.randint ()?

random.randint (a, b) returns an integer from "a" to "b".

The difference is

The difference between including or not including the last number! random.randrange (a, b) does not include the last value, so combine it with len (array) Convenient for iterating arrays!
