All rights reserved Summary: in this tutorial, you’ll learn various ways to concatenate strings in Python. Python provides you with various ways to concatenate one or more strings into a new string. Since Python string is immutable, the concatenation always results in a new string. 1) Concatenating literal stringsTo concatenate two or more literal strings, you just need to place them next to each other. For example:
Output:
Note that this way won’t work for the string variables. 2) Concatenating strings using the + operatorA straightforward way to concatenate multiple strings into one is to use the + operator:
And the + operator works for both literal strings and string variables. For example:
Output:
3) Concatenating strings using the += operatorSimilar to the + operator, you can use the += operator to concatenate multiple strings into one:
Output:
4) Concatenating strings using the join() methodThe
Output:
The
Output:
In this example, we use the The following example use the
Output:
5) Concatenating strings using the %-formattingString objects have the built-in % operator that allows you to format strings. Also, you can use it to concatenate strings. For example:
Output:
In this example, Python substitutes a 6) Concatenating strings using the format() methodYou can use the
Output:
In this example, you use the 7) Concatenating strings using f-stringsPython 3.6 introduced the f-strings that allow you to format strings in a more concise and elegant way. And you can use the f-strings to concatenate multiple strings into one. For example:
Output:
Which method should you use to concatenate stringsEven though there’re multiple ways to concatenate strings in Python, it’s recommended to use the Did you find this tutorial helpful ? Concatenation means joining strings together end-to-end to create a new string. To concatenate strings, we use the + operator. Keep in mind that when we work with numbers, + will be an operator for addition, but when used with strings it is a joining operator. Even though there're multiple ways to concatenate strings in Python, it's recommended to use the join() method, the + operator, and f-strings to concatenate strings. += operator You can append another string to a string with the in-place operator, += . The string on the right is concatenated after the string variable on the left. If you want to add a string to the end of a string variable, use the += operator. Concatenating means obtaining a new string that contains both of the original strings. In Python, there are a few ways to concatenate or combine strings. The new string that is created is referred to as a string object. In order to merge two strings into a single object, you may use the + operator. |
