$>>>$ def print$\_$lyrics$()$:

$...$ print$("$I$\text{'}$m a lumberjack, and I$\text{'}$m okay."$)$

$...$ print$("$I sleep all night and I work all day."$)$

$...$

To end the function, you have to enter an empty line.

Defining a function creates a function object, which has type function:

$>>>$ print$($print$\_$lyrics$)$

$>>>$ type$($print$\_$lyrics$)$

The syntax for calling the new function is the same as for built$-$in functions:

$>>>$ print$\_$lyrics$()$

I$\text{'}$m a lumberjack, and I$\text{'}$m okay.

I sleep all night and I work all day.

Once you have defined a function, you can use it inside another function. For example, to

repeat the previous refrain, we could write a function called repeat$\_$lyrics:

def repeat$\_$lyrics$()$:

print$\_$lyrics$()$

print$\_$lyrics$()$

And then call repeat$\_$lyrics:

$>>>$ repeat$\_$lyrics$()$

I$\text{'}$m a lumberjack, and I$\text{'}$m okay.

I sleep all night and I work all day.

I$\text{'}$m a lumberjack, and I$\text{'}$m okay.

I sleep all night and I work all day.

But that$$s not really how the song goes
