Python String join()
Python String join() is used to join all items in given iterable with this string in between them, and returns the resulting new string.
In this tutorial, we will learn the syntax and examples for join() method of String class.
Syntax
The syntax to call join() method on string x in Python is
x.join(iterable)
where
| Parameter | Required / Optional | Description |
|---|---|---|
| iterable | Required | A Python iterable like List, Tuple, Set, etc. |
Examples
In the following program, we take a list of strings, and join these items in list with the string '--' using join() method.
Example.py
x = ['apple', 'banana', 'cherry'] result = '--'.join(x) print(result)Try Online
Output
apple--banana--cherry
In the following program, we take a tuple of strings, and join these items in tuple with the string ',' using join() method.
Example.py
x = ('apple', 'banana', 'cherry')
result = ','.join(x)
print(result) Try Online Output
apple,banana,cherry

Example.py
x = {'apple', 'kiwi', 'mango'}
result = ' '.join(x)
print(result) Try Online Output
mango kiwi apple
Conclusion
In this Python Tutorial, we learned how to join the items of given iterable and form a string using join() method, with examples.
