03 - Built-In Functions in Python
We learn about some basic functions built into Python, and how to get help on functions.
Summary:
Functions are Python commands that return a result
Commonly-used built-in functions include `max`, `min`, and `round`
A function may take zero or more arguments
Functions may only work for certain (combinations of) arguments
Functions may have default values for some arguments
Fix syntax errors by reading the source code, and runtime errors by tracing the program's execution
Use the built-in function `help` to get help for a function
The Jupyter Notebook has two other ways to get help
use a `?` followed by the function name
position cursor over command name and press the `shift` + `tab` keys
Python reports a syntax error when it can't understand the source of a program
Python reports a runtime error when something goes wrong while a program is executing
