Import Statements

Python has various built-in functions, that include print(), input(), len() and a lot other ones. Another exciting thing about Python are the set of modules they provide, called the standard library. Each module is a Python program that contains a related group of functions that can be embedded in your programs. For example, the math module has mathematics-related functions, the random module has random number–related functions, and so on.

To use the functions from a module, we need to learn how to use the import function. In code, an import function includes:

1. The import keyword
2. The name of the module
3. More module names (optional), which are seperated by commas

Example:

import random
for i in range(0,10):
    print(random.randint(1,10))

This function prints random integers between 1,10 (excluding 10) ten times. randint() is a function provided by the random module and can be used in the way we just showed.

The result would be:

10
2
2
4
8
9
10
5
7
1

NOTE: When you type the same program in the console, it will give a different output as different random numbers will be generated.

An alternative form of the import statement is composed of the from keyword, followed by the module name, the import keyword, and a star; for example, from random import *. This imports all the functions of the random module.
