Python has a lot of instructions for us to use. They are part of the language and can be used by everyone. print is a good example of this.

Sometimes people create useful code that can be shared and used by other people.

Code that is created for a purpose like this is called a module or library.

A good example for us is the random module.

When we use the import instruction to import a module, we can then use functions from that module.

In this example random is a module full of useful functions related to random numbers. One of the functions is randint(from, to) which returns a random number between the numbers from and to.

Try running this code a few times to see the different results.

Here's another example, which could be useful.
