def calculator(operator, num1, num2):
    if operator == '+':
        return num1 + num2
    elif operator == '-':
        return num1 - num2
    elif operator == '*':
        return num1 * num2
    elif operator == '/':
        return num1 / num2
    else:
        return 'Invalid operator'

print(calculator('+', 1, 2))
print(calculator('-', 4, 2))
print(calculator('*', 2, 5))
print(calculator('/', 8, 4))
print(calculator('%', 8, 4))

Output

3
2
10
2
Invalid operator

Explanation

In this program, the calculator() function takes three arguments: an operator, and two numbers. The function uses an if...elif...else statement to check the value of the operator and performs the appropriate arithmetic operation. The function then returns the result of the operation, or an error message if an invalid operator is used.

You can test the program by calling the calculator function with different operators and operands.
