In this Python Beginner Tutorial, we will begin learning about the string data type. Text contains human-readable messages, represented as a sequence of Unicode codepoints. 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. The join() takes a string separator e.g. Python 3: this string literal is a "str" object that stores Unicode code points by default. Essentially you can actually place the variable into the string, if you follow a set of rules.

We can specify a variable name directly in an f-string, and the Python interpreter will replace the variable name with the data value corresponding to it. In this Python tutorial, we introduce all the different ways you can create strings. Create a for loop and build an if statement for every iteration such that if it detects a presence of a punctuation character, that would be replaced by a white space. However, Python does not have a character data type, a single character is simply a string with a length of 1. The above would be the preferred method if you want to concatenate only two byte strings.
