A Python function to compute the remainder of two input numbers.
The task is to create a Python function that uses the `%` operator to find the remainder of a division operation. This function should divide `num1` by `num2` and returns remainder. If `num2` equals 0, the function should return "Invalid operation: division by zero." ### Parameters - `num1` (int): Specifies the dividend in the division operation. - `num2` (int): Specifies the divisor in the division operation. ### Return Value - If `num2` is not 0, the function returns the remainder from the division of `num1` and `num2`; - If `num2` is 0, the function should return the string "Invalid operation: division by zero." ### Examples ```python # 1 divided by 3 has a remainder of 1 remainder_calculation(1, 3) # returns: 1 # 5 divided by 5 has a remainder of 0 remainder_calculation(5, 5) # returns: 0 # 7 divided by 2 has a remainder of 1 remainder_calculation(7, 2) # returns: 1 # Division by 0 is not valid remainder_calculation(1, 0) # returns: "Invalid operation: division by zero" ```
