How give an for loop an maximum number, help pleace ?

[JamieVanCadsand]

Hey Python Programmers...

I try to learn python and i use 'python 3'. But i try to create an 'for loop'
with an maximum number. But it did't work. Can anyone help me ?...

# Importing:
import math

# Call Variables:
press = str(input("Press 'A' to start the program: "))

arrayX = int(input("Give 'X' Number: "))
arrayY = int(input("Give 'Y' Number: "))
arrayZ = int(input("Give 'Z' Number: "))

arrayStart = int(input("Start Number: "))
arrayRange = math.floor(int(input("Give an number of 'Floor': ")))


# Write 'for loop':
def program():
    for arrayRange in range(arrayStart, arrayX):
        for arrayRange in range(arrayStart, arrayY):
            for arrayRange in range(arrayStart, arrayZ):
                print("Array is Called in ", arrayRange, arrayX, arrayY, arrayZ)
                
                if(arrayRange >= 100):
                    arrayRange += 0



# Than... press 'A' to start this for loop:
if(press == "A"):
    press = "A"
    program()

This is an example what i like to try, an code like writting above... Can enyone help me
with how i can give an 'for loop' an max number ?...

Thanks, Jamie.
