calculate()

When I tried to open my script in Microsoft VS Code, I got this error message:

Traceback (most recent call last):
  File "e:\Python\Projects\VsCode\calculator\calculator_school.py", line 31, in calculate
    exit()
  File "D:\Schule\Phyton\lib\_sitebuiltins.py", line 26, in __call__
    raise SystemExit(code)
SystemExit: None

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "e:\Python\Projects\VsCode\calculator\calculator_school.py", line 36, in <module>
    calculate()
  File "e:\Python\Projects\VsCode\calculator\calculator_school.py", line 32, in calculate
    except input != possible_answers:
TypeError: catching classes that do not inherit from BaseException is not allowed

When I open it in my file explorer, the script closes itself in Cmd as it should. But in VS Code it just won't. Why is that?

CodePudding user response：

You can stop the script even with a break in this case. you're inside a single loop.

CodePudding user response：

You can exit without using try except statement. Try this:

def calculate():
  while True:
    operator = input("What operator do you wanna use(*,/, ,-)? ")
    possible_op = " -*/"

    if operator not in possible_op:
      continue
    try:
      number_1 = float(input("What is your first number? "))
      number_2 = float(input("What is your second number? "))
    except ValueError:
      continue

    if operator == " ":
      print(number_1   number_2) 
    elif operator == "-":
      print(number_1 - number_2) 
    elif operator == "*":
      print(number_1 *  number_2) 
    elif operator == "/":
      print(number_1 / number_2) 
    while True:
      print("Do you wanna calculate again? ")
      answer = input("(Y/N) ").lower()
      if answer == "y":
        return calculate()
      elif answer == "n":
        quit()
      else: 
        print("Wrong Input")
        continue 
calculate()
