Python is considered to be object-oriented, interpreted and high-level programming language along with dynamic semantics. It is beautiful for rapid app development. This tutorial is all about how to install Python 3.8 in Ubuntu 18.04, 19.04 and 19.10. It is used as the glue or scripting language to connect existing components all together due to its high built-in data structures all combined with the dynamic building and dynamic typing.

Python comes with a simple yet easy to learn syntax that is used to emphasise readability and thus reduce the cost of the program maintenance. Moreover, it is also used to support packages and modules that are used to encourage code reuse and modularity. The best part is that the extensive standard library and python interpreter is present in binary or source without any penny for all the major platforms and thus can be distributed freely.

Today programmers get in love with python due to its increased productivity that it provides. As it does not have any compilation step, therefore, the edit-test-debug is very fast. Debugging Python programs is very easy: any bug or lousy input shall not cause a segmentation fault.

However, if the interpreter finds an error, then it raises an exception. If the defence is not caught, then the interpreter prints a stack trace. The source-level debugger can allow inspection of a global and local variable, setting breakpoints, evaluation of arbitrary expressions, stepping through the code a line at a time and much more.

The debugger is therefore written in python and testifies to python’s introspective power. Moreover, another way in which you can debug a program is by adding a few print statements to the source: the fast edit-test-debug cycle makes such a practical approach very useful.
