一起使用 while 循环和 try-except

Question

this is my code:

while True:
    try:
        varA = int(input('enter your number'))
        varB = int(input('enter your second number'))
        break
    except ValueError:
        print('ValueError')

When varB does not run in terms of ValueError, the loop continues. Okay, but I do not want varA to run. (I want varA to run if the varB value does not give an error.)

Answer 1

Just use 2 loops.

while True:
    try:
        var_a = int(input("enter your number"))
        break
    except ValueError:
        print("ValueError")

while True:
    try:
        var_b = int(input("enter your second number"))
        break
    except ValueError:
        print("ValueError")

Meaning that you keep asking your first number until it does not produce any error. When no error occurs on your first variable, do the same with your second one.
