How to use join

Creating Custom Strings

Ok... What is join?

The join() method is a powerful string function in Python used to combine the elements of an iterable (like a list) into a single string.

It’s particularly useful when you need to format and display lists as strings, such as when printing a sentence, creating a comma-separated list, or combining data for output.

Syntax - How Join Works

Here's an example of how to create a comma separated list (string) from a list of items.
You can also do something like this:

result = ", ".join(words)

You can list the separator as a string, instead of using a variable!

Why Use Join

Simplifies Combining List Elements

- Instead of looping through a list and manually concatenating strings, join() combines everything in one step.

Customizable Separators

You can choose any separator, such as a comma, space, newline, or even no separator at all.

Improves Readability and Efficiency

Cleaner and faster than using string concatenation (+) in a loop.

This example joins all the words in the list with a SPACE CHARACTER
