Computer Programming: JavaScript, Python, HTML, SQL, CSS

Learning to code often means meeting several kinds of syntax and problem-solving at once. Computer Programming: JavaScript, Python, HTML, SQL, CSS gathers introductory material on five widely used programming and web technologies, with step-by-step explanations aimed at beginners and intermediate learners.

The collection is presented as two guides: one focused on Python, the other introducing JavaScript, HTML, CSS, and SQL. The Python section is especially methodical, moving from installation and the command line to the building blocks used in everyday code.

Start with Python’s Building Blocks 💻

The Python guide begins with setup on Windows, macOS, and Linux, then explains how to use the interactive interpreter and run saved scripts. From there, it works through variables and data types, numbers, operators, strings, conditions, and loops. Examples help connect each concept to the code and the output it produces.

From First Statements to Reusable Code

As the subject matter develops, the contents turn to functions and modules, classes and objects, inheritance and polymorphism, file handling, and exception handling. Lists, tuples, sets, and dictionaries each receive their own treatment, giving readers a tour of the core structures used to organize and work with data in Python.

Five Technologies, Two Guides

Alongside Python, the bundle introduces JavaScript, HTML, CSS, and SQL. That breadth offers a starting point for readers curious about both general programming and the technologies associated with building for the web, while keeping the topics organized into separate guides rather than treating them as one language.

A Beginner’s Reference with a 2019 Viewpoint

The introduction says readers need not already know how to code, though some familiarity with using a computer, opening a terminal or command window, and installing software is assumed. The Python examples refer to version 3.6.6 or later, so readers should keep the book’s 2019 publication context in mind when comparing its setup instructions with current software.

The contents also list a chapter on black-hat hacking tips. The book is aimed at learners seeking a broad first encounter with programming concepts and several foundational languages.
