Lesson #15: Modules
A module is a file containing Python code that can be reused in other Python code files.
Create The First Module
To create a module just save the code you want in a file with the file extension .py.
In this example, we will create a file named adder.py with the following code.
def add(x, y):
return x + y
return x + y
Import The Module
Now we can use the module we just created, by using the import statement.
import adder
results = adder.add(10, 20)
print(results)
results = adder.add(10, 20)
print(results)
Renaming a Module
You can create an alias when you import a module, by using the as keyword.
In this example, we will create an alias for the module adder.py.
import adder as a
results = a.add(10, 20)
print(results)
results = a.add(10, 20)
print(results)
