Random string generation with upper case letters and digits

Question

I want to generate a string of size N.

It should be made up of numbers and uppercase English letters such as:

• 6U1S75
• 4Z4UKK
• U911K4

Answer 1

import uuid
lowercase_str = uuid.uuid4().hex  

lowercase_str is a random value like 'cea8b32e00934aaea8c005a35d85a5c0'

uppercase_str = lowercase_str.upper()

uppercase_str is 'CEA8B32E00934AAEA8C005A35D85A5C0'
