Python Handbook For Beginners: What Do You Need to Know?

Python was first created as a hobby project by Guido V Rossum in 1989 and has come a long way since. Today, Python stands as one of the very few official programming languages of Google, owing to its efficiency and ease of use. 

According to a survey put forward by Google Trends partnered with GitHub in 2020, Python bagged the position of most popular programming language. The popularity determination was simply done by comparing most searched languages on Google, and Python surpassed both Java and JavaScript by a wide margin.

Concerning the usage of programming languages by worldwide developers, Python bagged the third position in 2021, just after JavaScript and HTML/CSS. 

So, if you’re wondering whether to opt for a python tutorial for beginners or not, here is a piece to help you decide.

Python: What is it?

It is an object-oriented, general-purpose, interactive, and high-level programming language which was the brainchild of Guido van Rossum. The name is derived from Rossum’s favourite TV series, “Monty Python’s Flying Circus.” The versatility and simplicity of the Python language make it ideal for those who want to learn Python. 

Amazing features of Python

In this python tutorial for beginners, you can also explore the fantastic features of the Python programming language, which contributes to its popularity and value. 

It is interpreted and interactive

With Python, you need not opt for program compilation before executing it. Instead, it can be processed by an interpreter during the runtime. Furthermore, it is interactive because you have a scope of interaction with the interpreter directly and write your own programs.

It is object-oriented

Since Python is object-oriented, it allows for code reusability. Python lets the developers design an application with minimised coding.

Python can be integrated

One of the excellent features of Python is that it can be integrated with any other programming language, be it C, Java, or C++.

It is a beginner’s language

Python is known for its simple structure, lesser keywords, and clear-cut syntax. This makes it easy to learn for beginners, and amateurs can pick up the language quicker. It is also an open-sourced, free software making it accessible to a large population.

It comes with a bulk library

Python has a portable broad library for multiple fields, like machine learning, web development, etc. This library is also cross-platform compatible and thus runs well in Windows, Linux, UNIX, etc. Learn more about the libraries of Python.

Data types available in Python

In any programming language, the data type is a vital component. In Python, a data type is a class that contains variables (or objects). Here are the essential data types one can find in Python:

  • Python Numbers: This programming language supports complex numbers (defined as complex), integers (defined as int), and floating-point numbers (defined as float). Python also supports number type conversion, termed coercion, where you can convert integers to float or vice versa.
  • Python List: It is a sequential list of items defined within brackets and comma-separated. One speciality of the Python list is that all the items here don’t need to be of the same type. Example: x = [6.9, 4, ‘Python’].
  • Python Tuple: In Python, a tuple is quite similar to a list because both are sequential listed items. The difference is that changing the elements once assigned is restricted in a tuple, which isn’t the case with a list. Example: tup = (7, 1+4js, ‘Python’).
  • Python String: Python strings are character sequences that are enclosed by quotations.
  • Python Set: Python sets are unordered item collections where all elements are unique. Example: s = {2,5,8,9,4}.

What is Python used for?

Python has made its way to several fields due to its all-round nature. Some of the areas are:

  • Web applications
  • Software development
  • Auditory applications
  • Visual applications
  • Artificial intelligence
  • 3D CAD-based applications
  • Machine learning

Multiple Python flavours

Python is available in an array of flavours like:

  • Jython, which was earlier called JPython. It is designed for Java platform running.
  • CPython, which is written in C and is one common Python implementation.
  • Brython or  Browser Python that runs in a browser.
  • PyPy, which is a Python language implementation.
  • IronPython is an open-sourced implementation of the programming language.

Which companies use Python?
