Begginer Python To Advance Guide

Bilkul, Python seekhna ek behtareen faisla hai, khaas karke agar aapka goal software development ya data science hai. Beginner se advanced tak ka safar step-by-step hota hai.

Niche ek structured roadmap diya gaya hai jo aapko zero se hero banane mein madad karega:

Phase 1: Python Fundamentals (The Basics)

Sabse pehle aapko language ka syntax aur structure samajhna hoga.

  • Installation & Setup: Python aur ek achha Code Editor (VS Code ya PyCharm) install karna.

  • Variables & Data Types: Integers, Floats, Strings, aur Booleans samajhna.

  • Basic Operators: Arithmetic ($+$, $-$, $*$, $/$), Comparison ($==$, $!=$, $>$, $<$), aur Logical (and, or, not).

  • Input/Output: print() aur input() function ka use.

Phase 2: Logic Building

Yahan aap seekhte hain ki program ko "sochna" kaise sikhayein.

  • Conditional Statements: if, elif, aur else.

  • Loops: for loops aur while loops ka istemal karke tasks repeat karna.

  • Lists, Tuples, & Sets: Data ko collect aur organize karna.

  • Dictionaries: Key-value pairs ke sath kaam karna (kaafi important hai).

Phase 3: Intermediate Python (Efficiency)

Jab basics clear ho jayein, tab code ko organize karna zaroori hai.

  • Functions: Reusable code likhna aur arguments pass karna.

  • File Handling: Text files ko read aur write karna.

  • Exception Handling: try-except ka use karke errors ko handle karna taaki program crash na ho.

  • Modules & Packages: Dusron ka likha hua code (libraries) use karna.

Phase 4: Object-Oriented Programming (OOPS)

Bade projects banane ke liye OOPS ka concept aana bahut zaroori hai.

  • Classes & Objects: Real-world entities ko code mein badalna.

  • Inheritance & Polymorphism: Code ko modular aur clean banana.

Phase 5: Advanced Python & Specialization

Yahan aap decide karte hain ki aapko kis field mein jana hai.

  • Data Science/AI: Pandas, NumPy, Matplotlib, aur Seaborn seekhna.

  • Web Development: Django ya Flask frameworks.

  • Automation: Scripting aur Web Scraping (BeautifulSoup/Selenium).

Ek Chhoti si Advice:

Sirf videos dekhne se coding nahi aayegi. Har naye topic par kam se kam 5-10 chhote programs khud banayein.
