Python Course In Sanganer
Introduction : Python is a high-level, interpreted programming language renowned for its simplicity and readability. It has grown in popularity because to its adaptability, ease of learning, and diverse variety of applications. This document gives a detailed overview of Python, including its history, features, applications, and more. Python Course In Sanganer
History of Python
Guido van Rossum designed Python, and it was initially released in 1991. The language was created with the goal of making code easier to read and use. Python has undergone numerous important revisions, with Python 2 marking a watershed moment and Python 3 (published in 2008) becoming the standard version today. Python’s philosophy stresses simplicity and clarity, as evidenced by the Zen of Python, a collection of guiding principles. Python Course In Sanganer
Key Features of Python : Python has several distinguishing characteristics that make it a desirable language for developers:
Simple and Readable Syntax: Python syntax is simple and easy to learn, making it suitable for novices.
Interpreted Language: Python runs code line by line, making debugging easier.
Dynamically Typed: Variable types are decided at runtime, eliminating the requirement for explicit type declarations.
Cross-Platform Compatibility: Python works on a variety of operating systems, including Windows, macOS, and Linux.
Extensive Standard Library: Python includes a large number of built-in modules and functions, decreasing the requirement for external dependencies.
Object-Orientated and Functional Programming: Python supports a variety of programming paradigms, including object-oriented, functional, and procedural programming.
Large Community Support: Python has a large and active community, which offers comprehensive documentation, tutorials, and third-party libraries.
Python Syntax and Basics
Python’s simplicity is evident in its syntax. Below are some fundamental aspects: Python Course In Sanganer
Variables and Data Types : Python accepts a variety of data types, including integers, floats, strings, lists, tuples, dictionaries, and sets. x = 10 (integer) y = 3.14 Float Name = “Alice” # String is_active = True # Boolean.
Control Structures : Python has control structures like loops and conditionals. # Conditional Statements age = 18 if age > 18: print(“Adult”).
Otherwise: print(“Minor”)
# Loops For i in range(5), print(i)
i = 0 for i < 5: print(i)
i += 1
Functions : Functions facilitate code reuse and modularity Define greet(name): return f “Hello, {name}!” print(greet(“Alice”))
Object-oriented programming (OOP) : Python provides classes and objects to facilitate OOP.
Person: def __init__(self, name, age): self.name = name self.Age equals age.
def introduce(self): return “My name is {self.name}, and I am {self.age} years old.” Person = Person(“Alice”, 25); print(person.introduce()).
Applications of Python
Python is widely used in many disciplines, including:
Web Development : Frameworks like Django and Flask make Python a powerful choice for web development.
From flask import Flask. app = Flask(__name__). @app.route(‘/’); def home(): return “Hello, World!” If __name__ equals ‘__main__’: app.run()
Data Science and Machine Learning
Python is a major language in data research because to packages like NumPy, Pandas, Matplotlib, and Scikit-learn.
Import pandas as pd
data = {“Name”: [“Alice”, “Bob”], “Age”: [25, 30]
df = pd.DataFrame(data); print(df).
Automation and Scripting :
Import OS For file in os.listdir(“./”):
If file.endswith(“.txt”), print the file.
Cybersecurity : Python is frequently used in cybersecurity, particularly for penetration testing and network security.
Import hashlib. Python Course In Sanganer
function hash_string(string): returns hashlib.sha256(string.encode()).hexdigest()
print(hash_string(“password123”))
Game Development : Python is also used in game creation, with packages such as Pygame.
import pygame
pygame.init()
screen = pygame.display.set_mode((500, 500))
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
pygame.quit()
Python Libraries and Frameworks
Python has an extensive ecosystem of libraries and frameworks that extend its capabilities.
Web Development: Django, Flask, and FastAPI
Data Science: Pandas, NumPy, Matplotlib and Seaborn
Machine Learning: TensorFlow, Pytorch, and Scikit-learn
Automation: Selenium with PyAutoGUI
Advantages and Disadvantages of Python Advantages:
Simple to learn and utilize.
Significant community support
Comprehensive libraries and frameworks
Excellent readability and maintainability.
Cross-platform compatibility.
Disadvantages:
slower than compiled languages, such C++.
High memory utilization.
Not suitable for mobile development.
Future of Python :
Python continues to evolve, with growing adoption in AI, machine learning, and web development. Its simplicity and versatility ensure its relevance for years to come. Python Course In Sanganer
