Write the Python function get_positive which takes no parameter and returns a number greater than 0. This function should use the input function to ask the user for a number and convert it to an integer. It should then keep looping until it gets a number that is greater than 0. When it gets such a number, it should return that number.
```
def get_positive():
    number = int(input("Integer greater than 0: "))
    while number <= 0:
        print(number, "is not greater than 0")
        number = int(input("Integer greater than 0: "))
    return number
```
