Next exercises:

Generalized functions:
- Count occurrences for any column
- Count occurrences for an arbitrary number of columns

Add a default argument

def power(number, pow=1):
    """Raise number to the power of pow."""
    new_value = number ** pow
    return new_value

power(9, 2)

power(9)

Flexible arguments: *args (1)

def add_all(*args):
    """Sum all values in *args together."""

    # Initialize sum
    sum_all = 0

    # Accumulate the sum
    for num in args:
        sum_all = sum_all + num

    return sum_all

Let's practice!
