Final answer:
The 'import' function is used to include a module in your program. It allows you to use the functions and variables from that module. In Python, for example, 'import math' gives you access to the math module's functionality.
Step-by-step explanation:
The function used to include a module in your program is import. When you want to use a module that isn’t built into the language by default, you use the import statement. For example, in Python, if you want to use the math module, you would write import math at the beginning of your code. This allows you to access all the functions and variables defined in the math module.
Example of Importing a Module
To import a specific function from a module, use the from keyword. For instance:
from math import sqrt
This code snippet imports the sqrt function from the math module. Now you can use sqrt() directly in your program without prefixing it with math..
