When writing code, that would look like this: The final line in this code is the concatenation, and when the interpreter executes it a new string will be created. Use them based on your requirements. If some formatting is also required with concatenation, then use format () function or f-string. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. Note: To know more about format() function click here. Building long strings in the Python progamming language can sometimes result in very slow running code. Readability. In most of the programming languages, if we concatenate a string with an integer or any other primitive data types, the language takes care of converting them to string and then concatenate it.

There are a few ways of doing string concatenation in python depending on what you’re trying to … >>>. We can use Python f-strings on Python 3.6 or above to concatenate an integer with a string. This operator can be used to add multiple strings together. In the F-strings, we use the embed expressions inside string literals. Printing the string using print() If we want to directly print the concatenated string, we can use print() to do the concatenation for us. Many built-in methods and ‘+’ operator are used to combine string values in many programming languages. Square brackets [] can be used to access elements of the string. Using the += operator to concatenate two strings. String concatenation is a process when one string is merged with another string. Python does not support a character type; these are treated as strings of length one, thus also considered a substring. s='Welcome''to''Python' print (s)#Output:WelcometoPython s1='Welcome'+'to'+'Python' print (s)#Output:WelcometoPython. String Concatenation is the technique of combining two strings. We can store the combined string in another variable var3 which is separated by space. Examples might be simplified to improve reading and learning therefore, whenever it messy.
