Python modules and commonly used built-in modules

Problem:Explain what Python modules are and provide a n overview of commonly used built-in modules in Python. Describe how to import and use modules in Python programs.

Solution:Python Modules: A Python module is a file containing Python code, typically with functions, classes, and variables, that can be reused in other Python programs. Modules provide a way to organize and structure code, making it more manageable and promoting code reusability.

Importing Modules:

To use a module in Python, you need to import it using the import statement. Here's the basic syntax:

import module_name

After importing a module, you ca n access its functions, classes, and variables using the module name as a prefix. For example, if you import a module named math, you can use math.sqrtO to access the sqrt function defined in the math module.

Commonly Used Built-in Modules:

math Module:

import math
print (math.sqrt(16) )# 4.0

random Module:

import random 
print (random.randint (l, 10) )
# Generates a random integer between 1 and 10

datetime Module:

import datetime 
current_time = datetime.datetime.now() 
print (current_time)
