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.

How to manage git repositories with Python

by

Neither Python nor Git need presentations: the former is one of the most used general-purpose programming language; the latter is probably the most used version control system in the world, created by Linus Torvalds himself. Normally, we interact with git repositories using the git binary; when we need to work with them using Python, instead, we can use the GitPython library.

Tkinter stands for “Tk interface”: the package with the same name on many Linux distributions provides the Python bindings for the Tcl/Tk GUI toolkit. Although other graphical toolkit can be used from Python, like Qt or GTK, Tkinter is the standard (the Python IDLE editor and development environment is written using this toolkit, for example) and probably the easiest to work with.
