1. Introduction to Python
Python is a versatile, high-level programming language renowned for its
simplicity and readability. Created by Guido van Rossum and first
released in 1991, it's open-source and cross-platform, making it a
favorite among developers worldwide.
2. Key Features of Python
Readable Syntax
Python emphasizes code readability with its clean,
indentation-based syntax, making it easy to learn and
use.
Object-Oriented
Supports object-oriented programming (OOP) and
dynamic typing, allowing for flexible and powerful
applications.
Extensive Libraries
Boasts a vast standard library and a rich ecosystem of
third-party modules, simplifying complex tasks.
Versatile Applications
Ideal for scripting, automation, web development, data
science, and artificial intelligence, showcasing its broad
utility.
3. Popular Applications of Python
Python powers diverse applications, from interactive web platforms built with Django and Flask to complex data analysis
using Pandas and NumPy. It's also at the forefront of machine learning and AI with TensorFlow and PyTorch, alongside its
widespread use in automation, scripting, and GUI application development.
4. Python Basic Syntax Example
Variables and Dynamic Typing
Python uses dynamic typing, meaning you don't need to
declare variable types explicitly. Variables are created when
you assign a value to them.
# Assigning an integerage = 30# Assigning a
stringname = "Alice"# Assigning a floatpi =
3.14
Example: Adding Two Numbers
Basic arithmetic operations are straightforward. Here's how
to add two numbers and store the result in a variable.
# Define two numbersnum1 = 10num2 = 25# Add
them togethersum_result = num1 + num2#
Print the resultprint(sum_result) # Output:
35
