In python we have lots of built in functions. Built-in functions are globally available for your use. Some of the built in functions used frequently in python such as: *print()*, *len()*, *type()*, *int()*, *float()*, *str()*, *input()*, *list()*, *dict()*, *min()*, *max()*, *sum()*,*sorted*, *open*,*file*, *help()*, *dir*. In the following table you will see an exhaustive list of python built in functions taken from [python documentation](https://docs.python.org/2/library/functions.html).

As you can see from the above terminal, python has reserved words. We do not use reserved words to declare variables or functions. We will cover variables in the next section.
I believe, by now you are familiar with built-in functions. Let's do one more practice of built-in functions and we will move on to the next section
