What are modules in Python example?

I'll respond in English this time!

In Python, a module is a file that contains a collection of related functions, classes, and variables. Modules are used to organize code into logical units and make it reusable. Think of them as individual LEGO bricks that can be combined to build larger structures.

Here's an example of how you might structure a simple math module:

# mymath.py
def add(x, y):
return x + y
def subtract(x, y):
return x - y
def multiply(x, y):
return x * y
def divide(x, y):
if y == 0:
raise ValueError("Cannot divide by zero!")
return x / y

This module contains four functions: add, subtract, multiply, and divide. Each function takes two arguments, x and y, and returns the result of a mathematical operation.

To use this module in another Python script, you would import it using the import statement:

# main.py
import mymath
print(mymath.add(2, 3))  # prints: 5
print(mymath.subtract(5, 3))  # prints: 2
print(mymath.multiply(4, 5))  # prints: 20
try:
print(mymath.divide(10, 0))
except ValueError as e:
print(e)  # prints: Cannot divide by zero!

As you can see, the mymath module provides a way to encapsulate related code and reuse it in other parts of your program.

Python comes with many built-in modules that you can use, such as:

You can also create your own custom modules by defining a Python file and importing it into another script. This is a great way to organize your code and make it reusable!

I hope this helps illustrate the concept of modules in Python!

Python modules example w3schools

I'd be happy to provide information on Python modules and examples from W3Schools.

W3Schools is a popular online platform that provides tutorials, examples, and reference materials for web development, including HTML, CSS, JavaScript, PHP, and more. However, in this context, I will focus on Python modules and provide examples from W3Schools.

Python is a high-level programming language known for its simplicity and readability. It is often used for web development, scientific computing, data analysis, artificial intelligence, and more. The standard library of Python includes various modules that make it easy to perform tasks such as file input/output, network communication, database interactions, and more.

Here are some examples of Python modules and their uses:

Example:

import os
Create a new directory
os.mkdir("new_directory")
List the contents of the current directory
print(os.listdir())
Remove the directory
os.rmdir("new_directory")

Example:

import requests
Send a GET request to fetch data from a URL
response = requests.get("https://www.example.com")
Print the status code of the response
print(response.status_code)
Parse JSON data from the response
data = response.json()
Print the extracted data
print(data)

Example:

from datetime import datetime
Get the current date and time
now = datetime.now()
print(now)
Format the date and time as a string
formatted_date = now.strftime("%Y-%m-%d %H:%M:%S")
print(formatted_date)

Example:

import random
Generate a random integer between 1 and 100
random_integer = random.randint(1, 100)
print(random_integer)
Generate a list of random floating-point numbers
random_floats = [random.random() for _ in range(10)]
print(random_floats)

Example:

import math
Calculate the sine, cosine, and tangent of an angle
angle = 30
sin_angle = math.sin(math.radians(angle))
cos_angle = math.cos(math.radians(angle))
tan_angle = math.tan(math.radians(angle))
print(f"sin({angle}) = {sin_angle}")
print(f"cos({angle}) = {cos_angle}")
print(f"tan({angle}) = {tan_angle}")

These are just a few examples of the many Python modules and their uses. I hope this helps you get started with exploring the world of Python programming!
