When working with strings in Python, you may have to split a string into substrings. Or you might need to join together smaller chunks
to form a string. Python's In this tutorial, you'll learn about the As strings in Python are immutable, you can call methods on them without modifying the original strings. Let's get started. When you need to split a string into substrings, you can use the The In the above syntax: And setting When you split a string once, you'll get 2 chunks. When you split a string twice, you'll get 3 chunks. When you split a string ▶ Let's take a few examples to see the Let's start with
Now, call the
You can see that ▶ Let's now consider the
following example. Here,
Let's now split
As expected, the ▶ Let's now use the optional
Let's try to parse the returned list. Recall that
I hope you understand how the Python join() Method SyntaxNow that you know how to split a string into substrings, it's time to learn how to use the The syntax of Python's
Here,
In essence, the ▶ And it's time for examples. Python join() Method ExamplesIn the previous section on the Now, you'll form a string using the
📑 Note that the separator to join on should be specified as a string. You'll run into syntax errors if you don't do so, as shown below.
▶ To join the items in
The above
line of code joins items in You can specify any separator of your choice.
This time, you'll use 3 underscores (
The items in And you now know how you can form a Python string by putting together substrings using the ConclusionIn this tutorial, you've learned the following:

Get started When you call a string's split method the method divides the string into two substrings?When you call a string's split method, the method divides the string into two substrings. This is the first index in a string. This will happen if you try to use an index that is out of range for a string. This function returns the length of a string.
What string method returns the lowest index in the string where a specified substring is found?Python String find() method returns the lowest index or first occurrence of the substring if it is found in a given string. If it is not found, then it returns -1.
Which method would you use to determine whether a substring is the suffix of a string?The endsWith() method determines whether a string ends with the characters of a specified string, returning true or false as appropriate.
Which method would you use to determine whether a certain substring?Which method would you use to determine whether a certain substring is present in a string? The strip() method returns a copy of the string with all the leading whitespace characters removed but does not remove trailing whitespace characters.
