The Beginner’s Foundation: Getting Comfortable with Core Python

Here are some proven steps to become a successful Python developer –

Step 1: Master the Fundamentals

It doesn’t matter how advanced the field becomes; every Python developer must have a good grasp of the fundamentals. So, a solid understanding of basic Python skills is non-negotiable. Here are the details of what you should actually know about the basics of Python.

Concept	What should you learn?
Core Syntax and Data Types	Variables, operators, expressions Data types: strings, integers, floats, booleans String formatting and manipulation
Control Flow	Conditional statements (if, elif, else) Looping (for, while) List comprehensions
Functions and Scopes	Writing and calling functions Arguments and return values Variable scope (global vs local)
Object-Oriented Programming (OOP)	Classes and objects Constructors Inheritance, polymorphism, and encapsulation
Error Handling	Try/except/finally blocks Custom exceptions Using assert statements
Working with Files	Reading/writing text files JSON and CSV handling Context managers (with open)

Step 2: Explore the Python Ecosystem

When you have good knowledge of Python basics, you should start exploring the Python libraries. Python has become a powerful language not just for its syntax but also for the prominent ecosystems. These libraries help a Python developer understand the real-world use cases.

These are –

Popular Standard Libraries	os, sys, math, datetime, random re for regular expressions itertools, collections for advanced data manipulation
