In this Python tutorial, we introduce all the different ways you can create strings. In this tutorial, you will learn how to use Python 3's f-strings to create string For Python 2.x users: In the Python 2.x series, a variety of implicit conversions between 8-bit strings (the closest thing 2.x offers to a built-in binary data type) and Unicode strings were permitted. See this example, where we used the above list and converted this to strings by using the join method. Text contains human-readable messages, represented as a sequence of Unicode codepoints.
