Ever find yourself looking at the vast world of coding and drawing a blank as to which programming language to choose? Don’t worry, we have been there too. A great place to start in that case would be to learn one of the most widely used, popular and versatile languages, Python. Of course, like any other language, Python does have its fair share of technical jargon and complication but if you want something that will simplify the process to you, then look no further. This is the ultimate guide for Python for beginners inspired from beginner courses and tutorials. Let’s begin!
Beginner’s guide to Python
What can you do with Python?
Python is a multi-purpose programming language; thus, you can use it for a variety of different tasks. You can use Python for machine learning and AI (artificial intelligence) As a matter of fact, Python is the #1 programming language in machine learning and date sciences. It is also extensively used in web development as many amazing websites have been created with the help of Python. For instance, YouTube, Instagram, Pinterest, Spotify, Dropbox and so many more. Python can also be used to save your time and increase your productivity by automating repetitive tasks.
Features of Python for beginners
- It is simple and extremely easy to learn. It makes Python for beginners fun to adapt to and makes you think more for the solution than the syntax.
- Python code is very portable. You can share your code with anybody you want and it would result in the same performance.
- Code in python is interpreted line-by-line. This makes the analysis, management of memory and CPU, and debugging of code that much easier.
- It is a free, open-sourced programming language. Modifications to this code are also allowed without any problems.
- Python supports beginners by providing them with massive libraries and communities of coders to help them navigate their way through the world of Python.
- Python supports the integration of other programming languages with itself to run certain functions that can be better performed by other coding languages.
Python Programming Tutorial for beginners
To start off, you will need to visit www.python.org to download the latest version of python onto your system. Along with this, you will need to download and install a code-editor to write our code and execute is. One of the most popular ones for Python is Pycharm but there are many others like it online. A language like Python deals with ‘strings’ Strings are nothing but sequences of data in your code. Always remember, whenever you are using textual data in your Python code, always surround it with quotation (“”) marks to make it valid.
Just like many other programming languages, Python relies on the coder to type a certain function into the code for it to execute results. For instance,
print (“Python Tutorial for Beginners”)
In the aforementioned example, the word ‘print’ acts as a function that directs the code to print out an output that says, “Python Tutorial for Beginners”
Python also makes use of variables. We use variables to temporarily store data in a computer’s memory, for instance, the price of a product, someone’s age, etc. Say we were talking about age; our python variable would look something like the following:
age = 21
Within this example, we are attaching the value ‘21’ with the label of the term ‘age’ and storing it temporarily in a computer’s memory. To print this variable out, you just need to combine the print function to this step as follows:
Since the value of the term ‘age’ = 21, our output would display the value ‘21’ of the age variable. Since Python code is interpreted and executed line-by-line, from top to bottom, of you were to type another value for the ‘age’ variable, the program would only consides the latest change you may have made. For instance,
age = 21
print (“I am”)
age = 25
Similarly, Python relies on the following basic concepts:
- Variables, Data Types and Operators: this refers to the different types of date you can use within Python, such as numeric, lists, double and more.
- Arrays: this is used to store data in a structured manner.
- Recognising how the flow control of the code works and how you can modify and manipulate it using loops (for loop + while loop) and conditional statements.
- Creation of methods to performs certain functions ranging from simple to mind-numbingly complicated tasks.
- Handling of files, wherein you can read data from files and write new date to files.
- Understanding OOPs by understanding the importance of classes and objects.
- Practice, practice, practice programming!
As a beginner, why should you choose Python?
Why Python? You may ask. Well, here is exactly why.
- Python is the best programming language to get started off with. Its easy syntax and high-level features make it favourable for anyone to start with programming, be it a child or a veteran.
- Python is an open-source language, which implies that it is absolutely free of cost. Thousands of programmers come together everyday to try and make Python better, faster and more efficient.
- Python can be used to make almost anything. Desktop, mobile, machine learning, AI, you name it, Python will suit your needs.
- Support from a massive community in the form of solutions and updates that will help any beginner overcome their challenges.
As a beginner learning Python, the aforementioned information and details should help you start off your journey into this otherwise unknown terrain. Remember, you will only get better at coding as long as you relentlessly practice programming with Python. And since it is an easy and one of the most forgiving programming languages, there is always more to learn and always room to grow. Stay tuned for more such articles as we dive deeper into the nuances of Python and other similar programming languages, for beginners and experts alike. Happy learning!
