What are the methods of Python string concatenation

This article mainly explains "what are the methods of Python string concatenation". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what are the methods of Python string concatenation.

Method 1: connect with plus sign

Many languages support the use of plus signs to concatenate strings, and Python is no exception. You can simply add two or more strings to complete concatenation.

Method 2: use the% operator

Prior to Python 2.6, the% operator was the only way to format strings, and it could also be used to concatenate strings.

Method 3: use the format method

The format method is a string formatting method that appears in Python 2.6 instead of the% operator, and can also be used to concatenate strings.

Method 4: use f-string

Python 3.6introduces Formatted String Literals (literal formatted string), which is an evolutionary version of the% operator and format method for short. The method of concatenating strings using f-string is similar to that of using the% operator and format method.

Method 5: use the str.join () method

A string has a built-in method, join, whose argument is a sequence type, such as an array or tuple.
