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.

How do you join three strings together?

Concatenation is the process of appending one string to the end of another string. You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. For string variables, concatenation occurs only at run time.

How do you concatenate a list in Python?

The most conventional method to perform the list concatenation, the use of “+” operator can easily add the whole of one list behind the other list and hence perform the concatenation. List comprehension can also accomplish this task of list concatenation.
