Using Iterable As Function Arguments

12 Jul 2020

Create Arguments

# Create a list with three values
scores = [1,2,3]

# Create a dictionary with a single key-value pair
scores_with_names = {'amy_score': "200"}

Create Function With Positional Arguments

# Create a function with three positional arguments
def show_team_scores(jack_score, amy_score, sarah_score):
    # Print each of the positional arguments
    print(jack_score, amy_score, sarah_score)

# Run the function with * and an iterable object (in this case a list)
show_team_scores(*scores)

1 2 3

Create Function Using Keyword Arguments

# Create a function with three keyword arguments with default values
def show_team_scores(jack_score=0, amy_score=0, sarah_score=0):
    # Print each of the keyword arguments
    print(jack_score, amy_score, sarah_score)

# Run the function with ** and a dictionary
show_team_scores(**scores_with_names)

0 200 0

Notice how jack_score and sarah_score used the default values, while amy_score used the argument value we defined in scores_with_names.
