Python Modules

In Python, modules are files containing Python code that define functions, classes, and variables. They provide a way to organize code into reusable units and enable modular programming by allowing components to be imported and used in other Python programs or modules.

def greeting(name):
  print("Hello, " + name)

person1 = {
  "name": "John",
  "age": 36,
  "country": "Norway"
}
                

Import module

import mymodule

mymodule.greeting("John")
                

Import from module

from mymodule import person1

print (person1["age"])
                

Built-in modules

import platform

x = platform.system()
print(x)
