The join() method is a string method and returns a string in which the elements of sequence have been joined by str separator. In this tutorial we will cover Python string operations: concatenation, multiplication, indexing and slicing. You may also be familiar with the %operator (called a modulo), which allows you to perform string replacements like this (using a predefined variable "month" for substitution): While also valid, this approach is more or less obsolete (Python 3 introduced the format()method, which was back … String objects are immutable in python and any concatenation operation creates a new string, copies the old string character by character and then … How to concatenate numerical vectors and a string to return a string in R? >>> orig_string = 'Hello' >>> orig_string + ', world' 'Hello, world' >>> orig_string 'Hello' >>> full_sentence = orig_string + ', world' >>> full_sentence 'Hello, world'. Python provides many built-in functions for string manipulation. Use the + character to add a variable to another variable: Merge variable a with variable Let us now know about some more tricks of string concatenation in python. If you have to concatenate sequence of strings with a delimited, then use join () function. If you have a fewer string to concatenate then you may use the + operator. generate link and share the link here. This approach is simple, but it is messy, inefficient, and prone to error (ever forget the spaces? 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.
