Return values in Python - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the return statement do in a Python function?

It sends a value back to the place where the function was called, allowing the program to use that value later.

beginner

Can a Python function return more than one value?

Yes, by returning multiple values separated by commas, Python actually returns a tuple containing those values.

beginner

What happens if a Python function does not have a return statement?

The function returns None by default, which means it does not send any useful value back.

beginner

How do you capture the value returned by a function?

You assign the function call to a variable, like result = my_function(), so you can use the returned value later.

Is it possible to have multiple return statements in one function?

Yes, you can have several return statements inside different parts of a function to return different values based on conditions.

What does a Python function return if it has no return statement?

A An empty string

B 0

C None

D An error

If no return is used, Python functions return None by default.

How can a function return multiple values in Python?

A By returning a tuple of values separated by commas

B By using multiple <code>return</code> statements at once

C By printing values instead of returning

D By calling another function inside

Returning multiple values separated by commas actually returns a tuple containing those values.

What is the correct way to get the value returned by a function?

A Use <code>input()</code> after the function

B Call the function without assignment

C Print the function name

D Assign the function call to a variable

Assigning the function call to a variable stores the returned value for later use.

Can a function have more than one return statement?

A No, only one <code>return</code> is allowed

B Yes, to return different values based on conditions

C Yes, but only if they return the same value

D No, it causes a syntax error

Multiple return statements can be used to return different values depending on conditions.

What type of value does a function return if it uses return 5, 10?

A A tuple containing (5, 10)

B A list containing [5, 10]

C An error because of multiple values

D Only the first value 5

Returning multiple values separated by commas returns a tuple with those values.

Explain in your own words what a return value is and why it is useful in a function.

Think about how a function can give you information after it finishes.

Describe how you can return multiple values from a Python function and how to use them after calling the function.

Remember that multiple values come back as a single package you can unpack.
