A string usually contains a series of characters nested in quotation marks that can be represented as a text. In this article, we will talk about string concatenation in Python. This is the process of joining/adding one string to another. For example, the concatenation of "freeCode" and "Camp" is "freeCodeCamp". String concatenation is important when working with two or more separate variables (strings) that are combined to form a much larger string. This also enables you have separate units of a string even after combining them, just in case you need to use one string variable somewhere else in your code and not the entire string. To concatenate string in Python, we use the
In the code above, we created two variables ( We were able to combine the two variables by using the How to Add Spaces Between Concatenated StringsYou might notice that there was no space between the variables when printed. Here's how we can add spaces between concatenated strings:
You'll notice that there is a space between the quotation marks. If you omit the space then the strings will still be closely joined together. You can also add spaces at the end of a string when it is created and it will be applied when printed. Here's how you'd do that:
How to Create Multiple Copies of a String Using the * OperatorWhen we use the
Using the If we were to add a space at the end of the string, then the strings will be separated. That is:

DoryxDoryx 3674 silver badges12 bronze badges 2 Is there a concatenate function in Python?One of the most popular methods to concatenate two strings in Python (or more) is using the + operator. The + operator, when used with two strings, concatenates the strings together to form one.
How do you concatenate a number and a string in Python?In Python, we normally perform string concatenation using the + operator. The + operator, however as we know, is also used to add integers or floating-point numbers.. Using str() ... . Using format() ... . Using '%' format specifier. ... . Using f-strings. ... . Printing the string using print(). What is concatenation in Python example?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.
How do you concatenate 3 strings in Python?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.
