  • Modules & Packages

Introduction to Python

Before you launch into learning the basics of Python, you should familiarize yourself with the basic terminology and concepts you’ll run into during your first lessons. These include but are not limited to:

  • Object-Oriented Programming

Python is an object-oriented programming (OOP) language, which means it relies on data structures called objects, each of which can contain a combination of information (data) and coded procedures that determine the actions an object can take. OOP languages are well-known for being scalable, efficient and collaborative; they tend to work well in expansive or complex projects. 

  • Operators 

Python coders use operators to execute operations on values and variables. There are six major operators in the language. These include arithmetic, which performs basic mathematic operations like addition or subtraction; relational, which compares values and returns “true” or “false” according to a set condition (i.e., “true if left value is higher than right”); and logical, which perform AND, OR and NOT operations. The other three are bitwise operators, which perform bit-by-bit operations; assignment operators, which assign values to variables; and special operators, which perform complex operations.

Basics for Python

As you familiarize yourself with beginner Python concepts, you’ll need to understand more technical and practical aspects of the language, including how to install it and review its basic syntax. Additionally, you should endeavor to integrate programming exercises and free tutorials into your early education to help cement your new knowledge and give you opportunities to practice.

 

1. Installing

Before you can use Python, you’ll need to download and install an interpreter. Don’t be intimidated this process is simple and easy, and many newer computers (namely HP) come with Python installed. If you need to check whether you have Python installed or need to verify the version you’re using, simply enter “python” in a command-line window. Doing so will prompt a Python interpreter to respond; you should see a version number in the initial display if you already have Python installed.

If you don’t have Python on your computer, you can venture over to the Python website and download a version that suits your needs and operating system (OS). Keep in mind that the version you download and install will depend on the OS you use. 

2. Learning the Basic Syntax

Before you can learn how to program in Python, you need to familiarize yourself with the language’s syntax. With its focus on readability and concision, Python is usually relatively easy for first-time coders to learn. Below, we’ve listed a few critical components of the language’s syntax. 

Comments

Comments exist outside of the code itself and are ignored by the Python interpreter and are denoted with the # symbol. You can use comments to provide insight to other programmers or leave helpful notes for your own reference. That said, it’s good practice to keep such comments under 72 characters and use them sparingly.

Keywords

All programming languages feature several keywords that are designed to facilitate certain actions and processes. These keywords play specific roles in Python’s syntax, so you should not use them for anything else, including variables. To view a full list of Python keywords, you can enter this command: >>> help(“keywords”).

Built-in Data Types

Python features several built-in data types which can be manipulated via operators and other functions. The data types Python uses include dictionaries, strings, numbers (including integers, floats and complex numbers), Booleans, sets, lists and tuples

Loops

Python offers two kinds of loops (for loops and while loops) for when code repetition is necessary. You may need to repeat a portion of the code to obtain a specific result. Loops make that process simpler; you can use the two loops in Python to make code repeat a certain number of times or until a specified condition is met.

Variables

Variables are defined as names that programmers attach to objects to make accessing those objects easier. Single-character variable names are discouraged in favor of more descriptive names that provide context to the referenced data.

Conditionals

Commands that fall into this category assess whether defined conditions are met and adjust a program accordingly. These commands tend to feature statements such as “if” and “if else.”

Functions 

Defined by the “def” keyword, functions are pieces of code that are dormant until the program commands them to run. These code blocks use parameters to define their input and produce data as an output.

Obtaining a fundamental understanding of Python syntax is essential for anyone who wants to master the language.

3. Try a few basic programming exercises

Once you become familiar with the language, you will benefit from tackling some programming exercises to practice your Python skills and solidify your knowledge. Here are some Python practice problems and activities you can try as you continue your education:

  • Convert temperatures from Fahrenheit to Celsius (and vice versa)
  • Calculate the average value of an integer set
  • Implement a binary or linear search
  • Find Nth term in the Fibonacci sequence
  • Print all items in a dictionary
  • Check if a string of numbers is a palindrome
  • Identify the correct date and time
  • Solve math problems like the Tower of Hanoi or Sieve of Eratosthenes

Naturally, you can manually accomplish some of these challenges, but the point of these exercises is to expand your knowledge of Python syntax through hands-on practice.

Projects to try on your own

Once you are familiar with Python syntax and are comfortable completing exercises and practice problems, you can start working toward taking on your own projects. Doing so will be excellent practice and can help you build a professional portfolio! Below, we’ve listed a few tasks you can try.

  • URL Shortener Managing lengthy or unruly URLs can be a pain, so URL shorteners are terrific resources that make URLs look more appealing without detracting from their functionality. You can use Python to create your own URL shortening program.
  • Text-Based Adventure Game While somewhat simple, this project is one of the most exciting beginner-level challenges new Python coders can try. Essentially, you create an adventure game that solely uses text to facilitate movement and action. With this project, be sure to include movement restrictions and a tracker to track user movement through the settings you create, as consistency is key.
  • Random Password Generator Strong, unique passwords are crucial for online security. A random password generator that takes input from users and generates secure passwords from that data is a productive and worthwhile Python project to tackle.
  • Digital Post-It Notes Creating a virtual version of sticky notes to track miscellaneous thoughts and agenda items is a great intermediate Python project. 
  • Typing Speed Test This project aims to create a program that calculates a user’s typing speed. The program could also display speed, accuracy and words per minute (WPM). You can use web-based source code for typing test programs online to make this project more efficient.
  • Expense Tracker This project uses Python libraries like Panda or Matplotlib to create a software application that allows users to track their expenses and develop insights into their spending or saving habits.

Tackling projects like the above can help you turn your theoretical Python knowledge into practical skills!

How long does it take to master Python?

Because Python places such a high focus on readability, it is often considered easier to learn than some other languages. Learning the fundamentals of Python without any prior knowledge or experience can take as little as two weeks. 

However, mastering the language can take much longer depending on your goals and the resources you decide to use. You may spend months or years working toward complete mastery, especially if you are committed to learning how to use relevant libraries and frameworks in addition to the language itself. The learning process takes time, but if you set specific goals, stick to a schedule and stay focused, you can achieve at least a fundamental understanding of Python within the span of a few weeks.

If you want to speed up the process, you may want to consider enrolling in a coding bootcamp. These intensive programs are designed to teach aspiring developers job-ready skills and languages in as little as three to six months. Beyond learning Python, you could pick up fluency in other marketable languages such as HTML, CSS and JavaScript. If you’re looking to break into the job market quickly, the bootcamp track might be your best bet!
