Do you want to become a Python developer but don’t know where to start? If that’s the case, you’re in the right place. In this Python 2021 roadmap, I will show you everything you need to know in order to become a python developer. Let’s jump right into it!

Step 1: Introduction

Table of Contents

First introduces yourself to the fundamentals of Python, what makes it so massively popular, and its benefits and limitations. It also compares Python with other languages like Java, Scala, and R.

  • Introduction to Python

  • A Career in Python
  • Python vs Java
  • Python vs Scala
  • Python vs R
  • Applications of Python
  • Compilers and Interpreters Available
  • Getting to Know the Python Interpreter

Step 2: Basics

We then learn basics of Python- variables, data types, and operators. also learn concepts like looping and decision making.

  • Python Variables
    • Python Variable Scope
  • Data Types in Python
  • Python Operators
    • Bitwise Operators
    • Comparison Operators
    • Operator Precedence
    • Ternary Operators
  • Python Decision Making
    • Switch-case in Python
  • Loops in Python
  • Numbers with Python
  • Python Strings
    • String Formatters and Escape Sequences
    • String Functions and Operations
    • The repr() Function

Step 3: Data Structures

Learn about containers like lists and tuples and operations performed on them. also learn about other containers like dictionaries and sets.

  • Python Lists
    • List Comprehension
    • The array Module
  • Python Tuples
    • The zip() Function
    • Tuples vs Lists
