What should a beginner learn in python reddit

As a beginner, it's essential to start with the basics and build your foundation in Python programming. Here are some key concepts and topics that you should focus on when learning Python:

Syntax and Basics

Indentation: Understand how indentation works in Python (4-space indentation is standard).

Variables: Learn about variable types (e.g., int, float, str), assignment, and manipulation. Data Types: Study basic data types such as lists, dictionaries, sets, tuples, and booleans. Control Flow: Familiarize yourself with if-else statements, for loops, while loops, and conditional expressions.

Functions

Defining Functions: Understand how to define a function with parameters and return values. Function Arguments: Learn about passing arguments by position (positional) and by keyword (keyword). Return Values: Study how functions can return multiple values using tuples or dictionaries. Lambda Functions: Explore the use of lambda functions for concise, one-time use cases.

Modules

Importing Modules: Learn about importing modules from Python's standard library (e.g., math, statistics) and third-party libraries. Creating Modules: Understand how to create your own Python module and include it in another script or project. Module Scope: Study the concept of scope within a module and its implications on variable naming.

Data Structures

Lists: Learn about list comprehensions, indexing, slicing, and manipulating lists. Tuples: Understand how tuples differ from lists and when to use each. Dictionaries: Study dictionary creation, access, iteration, and manipulation. Sets: Familiarize yourself with set operations (union, intersection, difference) and set comprehensions.

Error Handling

Try-Except Blocks: Learn about using try-except blocks to catch and handle exceptions. Exception Types: Study the different exception types (e.g., ValueError, TypeError, KeyError). Raising Exceptions: Understand how to raise custom exceptions and use them in your code.

File Input/Output

Reading Files: Learn about reading files using open() or file() functions. Writing Files: Study writing to files using write() or dump() methods. Pickle Module: Explore the pickle module for serializing Python objects (e.g., lists, dictionaries).

Web Development and Networking

Flask or Django Frameworks: Learn about popular web frameworks like Flask or Django for building web applications. Requests Library: Familiarize yourself with making HTTP requests using the requests library.

Best Practices and Resources

Code Style: Study the official Python style guide (PEP 8) for writing clean, readable code. Debugging: Learn about using print() statements, pdb module, or a debugger like PyCharm. Resources: Familiarize yourself with online resources like official Python documentation, Stack Overflow, and Reddit's r/learnpython community.

By focusing on these topics, you'll establish a solid foundation in Python programming. As you progress, you can explore more advanced concepts and libraries to further enhance your skills.

Can a beginner directly learn, Python?

I'm happy to respond in English for you this time!

Absolutely, beginners can directly learn Python! Python is an excellent language for new programmers, and its simplicity makes it an ideal choice for those who want to start coding right away.

Here are some reasons why:

Easy to read: Python's syntax is designed to be readable. The code structure is straightforward, making it easy for beginners to understand the logic behind the program. Forgiving: Python is a dynamically-typed language, which means you don't need to declare variable types before using them. This allows you to focus on learning concepts rather than worrying about syntax errors. High-level language: Python abstracts away many low-level details, making it easier for beginners to learn and understand complex programming concepts without getting bogged down in implementation details.

To get started with Python, I recommend the following:

Codecademy's Python Course: This is an excellent resource for beginners. It provides a comprehensive introduction to Python syntax, data structures, control flow, and functions. Python.org: The official Python website has an "Introduction" section that covers the basics of Python programming. Python Tutorial by Google: Google offers a free online course on Python programming, covering topics like variables, data types, conditional statements, loops, and functions.

Some popular resources for learning Python include:

Udemy's Python Course: This is another excellent resource that covers Python basics, web development, data science, and machine learning. Python Crash Course by Eric Matthes: This free online book provides an in-depth introduction to Python programming, covering topics like variables, control flow, functions, and file input/output.

Remember, the key to learning Python (or any programming language) is to:

Start with the basics Practice regularly Experiment and explore different areas of interest

Python has a vast range of applications, from web development to data science, artificial intelligence, and scientific computing. As you gain more experience and confidence in your coding skills, you can explore these areas further.

So, don't be afraid to dive right into the world of Python! With persistence and dedication, you'll be able to learn and master this fantastic programming language.
