How do I make function calls in Python?

How do I make function calls in Python?

In Python, you can call a function by using its name followed by parentheses. For example, if you have a function named my_function, you would call it like this: my_function().

Can you show me an example of a function that takes parameters?

Sure! Here's a simple example:

def greet(name):
    return f'Hello, {name}!'

print(greet('Alice'))

This function greet takes a parameter name and returns a greeting.

What if I want to return multiple values from a function?

You can return multiple values by separating them with commas. For example:

def get_coordinates():
    return (10, 20)

x, y = get_coordinates()

This function returns a tuple with two values.

How do I handle default parameters in a function?

You can set default values for parameters by assigning them in the function definition. For example:

def power(base, exponent=2):
    return base ** exponent

print(power(3))  # Uses default exponent 2
print(power(3, 3))  # Uses provided exponent 3
