Python Strings (With Examples) Any time you want to use text in Python, you are using strings. String interpolation is a term used to describe the process of evaluating a string value that is contained as one or more placeholders.

Here in this tutorial, we will walk you through all the four different Python String Format techniques and methods. Python String Format is a technique, which allows us to insert variable values inside a string using placeholders.

Python does not support a character type; these are treated as strings of length one, thus also considered a substring. As their name suggests, F-strings begin with "f" followed by a string literal. Übrigens ist Stringverkettung per '+' in der Python-Welt nicht sehr verbreitet. String in Variable konvertieren?
