Answer 1

global statement not define global variable instantion, only inform metod than you can use this existed global variable internaly.
https://docs.python.org/3/reference/simple_stmts.html#the-global-statement

So before call global variable you must define it outside method
eg. in first line of your code:

minnumb = maxnumb = lves = numb = 0 # line 1

Then some global variables are not described in the method, so you must add it.
def program1():
global lves #line 4

def computer():
global numb #line 43

I tested it for input 0, 0, 40 ... and it works.
