Example 5: If the strings are placed next to each other without + operator this will result in a concatenation. 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. One thing to note is th… Using String Formatting with the { } Operators. If some formatting is also required with concatenation, then use format () function or f-string. b into variable c: For numbers, the + character works as a mathematical operator: If you try to combine a string and a number, Python will give you an error: If you want to report an error, or if you want to make a suggestion, do not hesitate to send us an e-mail: W3Schools is optimized for learning and training. Python does not support a character type; these are treated as strings of length one, thus also considered a substring. We can store the combined string in another variable var3 which is separated by space. edit Concatenate strings in Python (+ operator, join, etc.) String concatenation means creating a new string by combining two or more string values.

In Python the string object is immutable - each time a string is assigned to a variable a new object is created in memory to represent the new value. In the above example, the variable var1 stores the string “Hello” and variable var2 stores the string “World”. Note: Strings are immutable, therefore, whenever it is concatenated, it is assigned to a new variable. If you concatenate or repeat a string stored in a variable, you will have to assign the new string to another variable in order to keep it. Square brackets can be used to access elements of the string. Experience.
