# Representing a variable-length argument list

# Think of 'args' as a tuple of positional arguments
def add(*args):
    return sum(args)

# This function works with any number of positional arguments
add(1, 2, 3, 4, 5)
# 15

# You can also use the '*' operator to 'explode' a list of arguments
numbers = [1, 2, 3, 4, 5]
add(*numbers) # unpacks the list into an argument list for the function
# 15

# Now we have args (one '*') and kwargs (two '*'s)
# args is a tuple just like before, kwargs is a dictionary of the provided
# keyword arguments
def dump_it(*args, **kwargs):
    print(args)
    print(kwargs)

# Any number of positional arguments or keyword arguments will work here
dump_it(1, 2, 3, color='blue')
# (1, 2, 3)
# {'color': 'blue'}
