How to install Python in Ubuntu?
“know the Power of Python by installing it into Ubuntu and learning “
A programming language that has drawn the interest of programmers in the world of programming is the one and only Python language. People who are thinking of a career in programming then he or she can start with Python first as it is in general use.
There are a number of industries like web development, artificial intelligence, data analysis, and much more where Python is used. The Python programming course fees are very affordable.
Python is an open-source language because of this the programming community can work together. Although Python 2.7 is already installed on Ubuntu, it is essential to remember that future versions, such as Python 3 and others, can be added. We’ll explore Python’s history, semantics, and syntax and in the end, the steps used to install it in Ubuntu through this blog.
Let’s get started and maximize Python in your Ubuntu environment.
Syntax of Python:
Python’s Syntax is simple and easy to understand and is based on the indentation method which means that the code blocks are defined by the level of indentation, not by explicit delimiters like brackets or curly braces. Choose the best Python Course in Faridabad is the best to learn all about Python. Below mentioned is an example of a Python function that calculates the factorial of a number:
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n-1)
The function is defined in this example using the ‘def’ keyword, and the defining code block is indented. To define their separate code blocks, the ‘if’ and ‘else’ statements are also indented.
Semantics of Python:
Despite the fact that Python’s syntax is made to be simple to read, its semantics are just as crucial. Since readability and maintainability are two areas where Python places a lot of emphases, code should be simple to comprehend, alter, and troubleshoot.
Semantics in Python is founded on a few fundamental ideas, including:
- Objects and classes: Python is an object-oriented language in it every concept is an object. If you want to define objects, classes are needed. Objects are those that include attributes (data) and methods (functions).
- Dynamic typing: The variable of Python are typed dynamically, which shows that they are decided upon at runtime not during compilation.
- Automatic garbage: This collection allows Python to manage the memory without including the explicit memory allocation or deallocation on the part of the programmer.
- Python features strong typing, which means that the type of a variable is required. Without expressly converting one of them, you cannot combine a string with an integer, for instance. Python programming course fees are the fees that you can afford and get back results of it.
The overall goal of Python’s semantics is to make programming simpler, more adaptable, and less error-prone.
A step-by-step guide to installing Python in Ubuntu
1. Ubuntu System Updation
The first step to do before installing Python is to update your system to the latest version available. The updation process can be done by starting the terminal and writing the written command in it :
sudo apt update && sudo apt upgrade
By writing this command you can update your system and install any new software that is available and that you want to install.
2. Python package installation
However Ubuntu has Python in it which is pre-installed, but you have to check whether is the latest version or not. If you want to know the version of Python that is installed on your system then you can write the written commands:
python3 –version
If you already have Python 3.6 installed in your system then you can skip this step. Or if you have any older version of Python installed or have not installed Python before then you can install it by writing the following command in the terminal:
sudo apt install python3
This command is written down so that it can install the latest version of Python 3 that was available in the Ubuntu repositories.
3. Install pip
Pip is known as the package manager of Python and it allows you to install and manage Python. The pip can be installed by writing the following command in the terminal:
sudo apt install python3-pip
For installing pip for Python 3 this command is used.
4. Verify the installation
You can check the versions by writing the following commands in the terminal to verify that Python and pip are installed correctly or not :
python3 –version
pip3 –version
After writing these commands you will get to know the versions of Python and pip installed on your system.

Conclusion
You will eventually discover that Python has been successfully installed on your Ubuntu system. You now have a strong foundation for Python if you follow this step-by-step tutorial to begin creating and exploring its myriad possibilities of it. Dreamer Infotech makes you learn all about Python. Keep this in mind while you continue learning Python and make sure you use the most recent versions and packages to fully utilize this formidable programming language.
Ubuntu Python installation is a straightforward process, not a difficult one. If you wish to work on several Python projects with various dependencies, virtualenv can also be installed. Once Python has been successfully installed, you can begin creating Python code and exploring the extensive world of Python programming.
