Learning Python

Dec 14, 2024 pm 03:30 PM

Introduction

Python is one of the most popular programming languages in the world—and for good reason. Known for its simplicity, versatility, and vast array of applications, Python has become a go-to choice for beginners and experts alike. Whether you’re looking to dive into web development, data science, machine learning, or automation, Python has something to offer everyone. Learning about Python was simpler than I had imagined though. Data types include Strings, Booleans, and Numbers. Fundamental material like defining variables, console logging values, and getting user input was easy for the most part.

Versatility

Python isn’t just for one type of programming. You can use it for:

  • Web development with frameworks like Django and Flask.
  • Data analysis and visualization with libraries like Pandas, Matplotlib, and Seaborn.
  • Machine learning and AI with TensorFlow and Scikit-learn.
  • Scripting and automation to make your workflows faster and smarter.

Explore Libraries and Frameworks

Once you’re comfortable with the basics, dive intosome of Python’s extensive libraries to tackle more complex tasks:

  • Use NumPy for numerical operations.
  • Try Flask for building simple web apps.

Installing Python

Download the latest version from the official Python website. Most systems come pre-installed with Python, but it’s a good idea to ensure you have the latest version.

Open VS Code

After installing Python, Open Visual Code and install Python.

Install the Python Extension

Go to the Extensions view by clicking the Extensions icon in the Activity Bar or pressing Ctrl Shift X. Search for "Python" select the one provided by Microsoft and click Install.

Python's Syntax

Python's syntax is known for it's simplicity and readability, making it a popular choice for beginners and professionals alike. It uses indentation instead of braces to define code blocks, and its clean, English-like syntax emphasizes clarity.

Printing in Python

name = "Jahmari"
print('Jahmari')

To print any type of data to the console, you must use the word print. Python's syntax is straightforward and mimics the English language, making it accessible for first-time coders.

Creating Variables
name = "Jahmari"
print('Jahmari')

Unlike JavaScript, Python doesn’t require you to use words like let, var and const making it extremely easy to read.

Control Flow
name = "jahmari"
age = 24
paragraph = """
I like movies and video games, I also like riding my bike. I love it when it rains because my plants get to grow.
"""

The if and else syntax is also similar to JavaScript especially the way it is structured, the only key difference is that JavaScript uses a curly bracket {} while Python uses : to in order to capture the code to be executed after the conditional statement.

Defining functions are also slightly different in terms of Syntax. To define a function in Python, you would have to use the word “def” and not const, let, or var like JavaScript.

Functions
if x > 5:
   print("x is greater than")
else:
   print("x is less than or equal to 5")

Comparison Between JavaScript and Python

JavaScript and Python are two of the most popular programming languages, widely used in web development, automation, data science, and more.

Despite their differences, they share several similarities, making them beginner-friendly and versatile. While JavaScript is traditionally used for front-end interactivity (e.g., handling user events), Python can handle similar tasks using frameworks like Tkinter for GUI development.

Both are known for their simplicity and readability, making them ideal for beginners. In addition, they have large, active communities that contribute to open-source projects, provide tutorials, and support learners on platforms like Stack Overflow.

Statistics on Python

According to this Stack Overflow Developer Survey 2024 rated by professionals among the top languages and technologies, Python is the third most used popular technology in the world. Python remains a highly popular and versatile language among developers. It is frequently used across various fields like data analysis, machine learning, web development, and scientific computing. Although JavaScript continues to lead in terms of overall usage (62.3%), Python consistently ranks as one of the most desired and admired programming languages due to its simplicity and wide application.

In addition to the shebang line, there are many ways to specify a Python interpreter: 1. Use python commands directly from the command line; 2. Use batch files or shell scripts; 3. Use build tools such as Make or CMake; 4. Use task runners such as Invoke. Each method has its advantages and disadvantages, and it is important to choose the method that suits the needs of the project.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
