in python is a mathematical operator classed as an interger. for example why isnt this code working

import randomscore = 0
randomnumberforq = (random.randint(1,10))
randomoperator = (random.randint(0,2))
operator = ['*','+','-']
answer = (randomnumberforq ,operator[randomoperator], randomnumberforq)
useranswer = input(int(randomnumberforq)+int(operator[randomoperator])+      int(randomnumberforq))
if answer == useranswer:
print('correct')
else:print('wrong')
Answer

You can't just concatenate an operator to a couple of numbers and expect it to be evaluated. You could use eval to evaluate the final string.

answer = eval(str(randomnumberforq)+ operator[randomoperator] + str(randomnumberforq))

A better way to accomplish what you're attempting is to use the functions found in the operator module. By assigning the functions to a list, you can choose which one to call randomly:

import random
from operator import mul, add, sub    if __name__ == '__main__':score = 0randomnumberforq = random.randint(1,10)randomoperator = random.randint(0,2)operator = [[mul, ' * '],[add, ' + '], [sub, ' - ']]answer = operator[randomoperator][0](randomnumberforq, randomnumberforq)useranswer = input(str(randomnumberforq) + operator[randomoperator][1] + str(randomnumberforq) + ' = ')if answer == useranswer:print('correct')else:print('wrong')
