Seperating int & str then addition? (Phyton)

Question

For example: we had the input “12+12” from user. How to separate this and code for math addition?

Answer 1

if I code something like this:

command = input(“enter a number (number - operator - number): “)

parseCommand = command.split()

if len(parseCommand) != 3:
print(“invalid entry”)
exit(0)

try:
number1 = int(parseCommand[0])
operator = parseCommand[1]
number1 = int(parseCommand[2])
except ValueError:
print(“you need to enter a numeric value”)
exit(0)

if operator == “+”:
print(command, “=“, number1 + number2)
elif operator == “-“:
print(command, “=“, number1 - number2)
elif operator == “*“:
print(command, “=“, number1 * number2)
elif operator == “/“:
print(command, “=“, number1 / number2)

# this code splits with spaces (12 + 12) and calculates the values entered.
# but how can I integrate the code you gave me here if there is no spaces between the characters that user entered.

#thank you so much. also a while circle would be more appreciated :)
