Introduction to Python

Python is a high-level, interpreted programming language. It is known for its simplicity and readability, making it a great choice for beginners and experienced developers alike. In this tutorial, we'll cover the basics of Python, including syntax, data types, and control structures.

Basic Syntax

Python uses indentation to define blocks of code. This is different from languages like Java or C, where you use curly braces {}.

# Python code block

print("Hello, World!")

Data Types

Python has several built-in data types, including integers, floats, strings, and booleans.

• Integers: Whole numbers, like 1, 2, and 3.
• Floats: Numbers with decimal points, like 1.5 and 3.14.
• Strings: Text, enclosed in quotes, like "Hello, World!".
• Booleans: True or False values.

# Data types in Python

age = 25          # Integer
height = 5.9      # Float
name = "Alice"    # String
is_student = True # Boolean

Control Structures

Python uses if-else statements and loops to control the flow of execution.

If-Else Statements

# If-else statements

if age > 18:
    print("You are an adult.")
else:
    print("You are a minor.")

Loops

Python has two types of loops: for and while.

For Loop

# For loop

for i in range(5):
    print(i)

While Loop

# While loop

count = 0
while count < 5:
    print(count)
    count += 1

Modules and Packages

Python has a vast ecosystem of modules and packages that you can use to extend its functionality. For example, you can use the requests module to make HTTP requests, or the numpy package for numerical computations.

# Using a module

import requests

response = requests.get("https://api.github.com")
print(response.json())

Conclusion

Python is a powerful and versatile language that can be used for a wide range of applications. Whether you're a beginner or an experienced developer, this tutorial should give you a good foundation in Python.
