![]() ![]() □ Note that the separator to join on should be specified as a string. The items in my_list are all names of fruits. Now, you'll form a string using the join() method to put together items in the returned list. In the previous section on the split() method, you split my_string into a list on the occurrences of commas. In essence, the join() method joins all items in using as the separator. is the separator that you'd like to join the substrings on.is any Python iterable containing the substrings, say, a list or a tuple, and.Now that you know how to split a string into substrings, it's time to learn how to use the join() method to form a string from substrings. I hope you understand how the split() method and the arguments sep and maxsplit work. This is why the portion of the string after the second comma is lumped together as a single item in the returned list.At this point, you've reached the maxsplit count of 2, and no further splits can be made.And you'll have 3 items, Apples, Oranges, and Pears,Bananas,Berries after the second split. The first comma is after Apples, and after the first split you'll have 2 items, Apples and Oranges,Pears,Bananas,Berries.Recall that my_string is "Apples,Oranges,Pears,Bananas,Berries", and we decided to split on commas ( ","). ▶ Let's now use the optional maxsplit argument as well by setting it equal to 2. my_string.split(",")Īs expected, the split() method returns a list of fruits, where each fruit in my_string is now a list item. Let's now split my_string on commas – set sep = "," or only specify "," in the method call. my_string = "Apples,Oranges,Pears,Bananas,Berries" ![]() Here, my_string has names of fruits, separated by commas. ▶ Let's now consider the following example. You can see that my_string has been split on all whitespaces and the list of substrings is returned, as shown above. Now, call the split() method on my_string, without the arguments sep and maxsplit. my_string = "I code for 2 hours everyday" ▶ Let's take a few examples to see the split() method in action. When you split a string k times, you'll get k+1 chunks. When you split a string twice, you'll get 3 chunks. When you split a string once, you'll get 2 chunks. If you'd like to split on the occurrence of the first comma, you can set maxsplit = 1.Īnd setting maxsplit = 1 will leave you with two chunks – one with the section of before the first comma, and another with the section of after the first comma. maxsplit has a default value of -1, which splits the string on all occurrences of sep.maxsplit is an optional argument indicating the number of times you'd like to split.By default, this method splits strings on whitespaces. It should be specified as a string.įor example, if you'd like to split on the occurrence of a comma, you can set sep = ",". sep is the separator that you'd like to split on.The split() method acts on a string and returns a list of substrings. When you need to split a string into substrings, you can use the split() method. In this tutorial, you'll learn about the split() and join() string methods with plenty of example code.Īs strings in Python are immutable, you can call methods on them without modifying the original strings. Python's split() and join() string methods help you do these tasks easily. Or you might need to join together smaller chunks to form a string. When working with strings in Python, you may have to split a string into substrings.
