Two other methods need special mention in the list of our solutions. Now let us try a few methods which do not use regular expressions. Let us have a look at the following program to see how the either-or meta-character works: import re In our case the delimiters that we need to specify using the | character are |*] A metacharacter is used to convey a special meaning to a regular expression. Method 3: Using Either Or (|) Metacharacter To Specify The DelimitersĪnother approach to solving our problem is to split the string using the split() function along with the either-or metacharacter | to provide/specify multiple delimiters within the string according to which we want to split the string. In this case, the set is used to find a delimiter and split the string into word characters accordingly. it is used to find a delimiter/separator. is used to return a match for any character EXCEPT alphabets (both Capital Letters and Small Letters) and Numbers, i.e.is used to match a set of characters within the string.() is used to keep or store separators along with the word characters.Let us have a look at the following example to see how this works: import re Here it is used to find the delimiters while splitting the string.Īnother way of splitting the string using regex is to split it using the split() function along with the () set. \W is a special sequence that returns a match where it does not find any word characters in the given string.() is used to keep or store the separators/delimiters along with the word characters.Let us examine and discuss the expression used here: One of the ways in which we can split the given string along with the delimiter is to import the regex module and then split the string using the split() function with the | meta-character. Let us have a look at the different regular expressions that can be used to solve our problem: Method 1: Using ‘(\W)’ You can learn more about the split() function by following this article. split() is an inbuilt method in Python which is used to split a string that matches a regular expression.The most efficient way of splitting the string and extract the characters along with the separators is to use regular expressions along with the split() function. Method 5: Split Using Line Break: splitlines().Method 4: Using a List Comprehension And Appending The Separator.
Method 3: Using Either Or (|) Metacharacter To Specify The Delimiters.Now that we have an overview of our problem, let us dive into the solutions without any delay! text = day'ĭesired Output: fig: The Blue Boxes represent the word characters/strings while the Yellow Boxes represent the delimiters/separators. Please follow the example given below to get an overview of our problem statement.
#Python split keep delimiter how to
Problem: Given a string in Python how to split the string and also keep the separators/delimiter?Ī sequence of one or more characters used to separate two or more parts of a given string or a data stream is known as a delimiter or a separator.Įxample: Consider that there’s a given string as shown in this example below and you need to split it such that the separators/delimiters are also stored along with the word characters in a list. Let’s dive into the problem in a step-by-step manner! You can try the first method in our interactive Python shell:Įxercise: Add more words with special delimiters to the text.
