# get operator as input in python

def operation(number1, number2, operator): if operator == '+': return number1 + number2 elif operator == '-': return number1 - number2

**Here is what the above code is Doing:**

1. It’s defining a function called operation.

2. It’s taking in three parameters: number1, number2, and operator.

3. It’s checking to see if the operator is a plus sign. If it is, it returns the sum of number1 and number2.

4. If the operator is not a plus sign, it checks to see if the operator is a minus sign. If it is, it returns the difference of number1 and number2.

5. If the operator is neither a plus sign nor a minus sign, it returns nothing.
