Master Python basics! Learn about modules, PIP, comments, escape sequences, and print statements in this beginner-friendly guide.

Python is a versatile and beginner-friendly language. Today, we’ll dive into key foundational topics: modules, PIP, comments, escape sequences, and the versatile print statement. These are essential for writing clean, efficient, and organized Python code.

1. Python Modules

Modules are pre-written Python code files that you can reuse in your projects.

What Are Modules?

• A module is simply a Python file containing definitions and statements.
• Examples: math, os, random.

Using Modules in Python

pythonCopy codeimport math  
print(math.sqrt(16))  # Output: 4.0  

• Use import to include a module.

2. PIP (Python Package Installer)

PIP is a tool to install and manage Python packages.

Installing a Package

bashCopy codepip install requests  

• Example: Installing the requests package for HTTP requests.

Checking Installed Packages

bashCopy codepip list

3. Python Comments

Comments are used to explain code and make it more readable.

Single-Line Comments

Use # for single-line comments.

pythonCopy code# This is a single-line comment  
print("Hello, World!")  

Multi-Line Comments

Use triple quotes (""" or ''').

pythonCopy code""" 
This is a multi-line comment.
It spans multiple lines.  
"""

4. Escape Sequences

Escape sequences let you include special characters in strings.

Common Escape Sequences

• \n → New line
• \t → Tab
• \\ → Backslash
• \' → Single quote
• \" → Double quote

print("Hello\nWorld")  
# Output:  
# Hello  
# World  

5. Print Statement

The print() function displays output on the screen.

Basic Syntax

print("Hello, Python!")  

Using Multiple Arguments

print("Name:", "Zeeshan", "Age:", 23)  

Formatting Strings with f-strings

name = "Zeeshan"  
print(f"Hello, {name}!")  

Conclusion

The topics covered today are the building blocks for writing effective Python programs. Commenting ensures readability, and code is reusable & extendable using modules and PIP. Output formatting is enhanced by escape sequences and the print statement.
