Many developers and programmers choose to use a Linux system as their work environment because of its stability, speed, and ease of use. To get started with programming Java, or to simply run Java applications or applets on Linux, you will need to install the appropriate Java software package. Although this is pretty easy to do, the instructions will vary depending on a user’s Linux distribution, what version of Java they wish to use, and whether they need the JDK (Java Development Kit) or just the JRE (Java Runtime Environment).
How to Use a Bash Script to Run Your Python Scripts
Python is a popular programming language used in a wide range of applications, from data analysis and scientific computing to web development and artificial intelligence.

List of Python Escape sequence characters with examples
When programming in Python, escape characters can be used in order to tell the compiler that it should treat the next character or characters differently. For example, we can tell Python to print a quote
" as an actual quote character, rather than interpreting it to be part of the Python code. Other special characters like
\t can create TAB spaces, and
\n can create new lines. In this tutorial, you will see a list of Python escape sequence characters and examples that you can use on a Linux system.
