What is the string concatenation operator?

Furthermore, what does the concatenation operator do?
The concatenation operator is usually expressed as simple juxtaposition (as with multiplication ). The strings over an alphabet, with the concatenation operation, form an associative algebraic structure with identity element the null string -a free monoid .
And, how does concatenation operator work on list in Python? The concatenation operator creates a new list in Python using the initial lists in the order they were added in. This is not an inplace operation. example list1 = [1, 2, 3] list2 = ['a', 'b'] list3 = list1 + list2 print(list3) Output. This will give the output − [1, 2, 3, 'a', 'b'] There are other ways to concatenate 2 lists.

Which is better string concatenation with + or f string?

From a readability standpoint, f-string literals are more aesthetically pleasing and easier to read than string concatenation. Also, as the answer from Daniel points out, f-strings are able to handle inputs of different types while using + requires both objects to be strings (or the overloading of the __add__, and __radd__ methods).
