Help debugging line 7 type error more arguments (5) than expected (1)
kolezko [41]

Answer:

import random

score = 0

for i in range(5):

   num1 = random.randint(1, 100)

   num2 = random.randint(1, 100)

   prompt = "What is " + str(num1) + "+" + str(num2) + "?"

   answer = int(input(prompt))

   result = (num1, num2)

   if answer == result:

       print("Well done!")

       score += 1

   else:

       print("incorrect")

print("Your score was", score)

Explanation:

Your error is on <em>line 7</em>, where you are providing multiple arguments to the input function, instead of 1.

One way to solve this is to create a variable prompt and concatenate all strings and variables within that variable to use for the input.
