10/30/2022 0 Comments Python split keep delimiterRegex to split String into words with multiple word boundary delimiters For example, will match either hyphen, comma, semicolon, dot, and a space character. The matches any single character in brackets. Note: we used meta character to indicate a list of delimiter characters. Target_string = "PYnative dot.com is for, Python-developer" Here we will use regex to split a string with five delimiters Including the dot, comma, semicolon, a hyphen, and space followed by any amount of extra whitespace. # Output Regex to split string on five delimiters # use OR (|) operator to combine two pattern Let’s take a simple example to split the string either by the hyphen or by the comma.Įxample to split string by two delimiters import re You can specify a pattern for the delimiters where you can specify multiple delimiters, while with the string’s split() method, you could have used only a fixed character or set of characters to split a string. With the regex split() method, you will get more flexibility. #Python split keep delimiter how to#In this section, we’ll learn how to use regex to split a string on multiple delimiters in Python.įor example, using the regular expression re.split() method, we can split the string either by the comma or by space. # Output Regex to Split string with multiple delimiters Result = re.split(r"\D", target_string, maxsplit=3) Result = re.split(r"\D", target_string, maxsplit=1) Here we will use the \D special sequence that matches any non-digit character. So let’s take a simple example to split a string on the occurrence of any non-digit. In simple words, if the maxsplit is 2, then two splits will be done, and the remainder of the string is returned as the final element of the list. The maxsplit parameter of re.split() is used to define how many splits you want to perform. # Output Īs you can see in the output, we got the list of words separated by whitespace. Word_list = re.split(r"\s ", target_string) Target_string = "My name is maximums and my luck numbers are 12 45 78" Now, The \s regex pattern will split the target string on the occurrence of one or more whitespace characters. Let’s add the metacharacter at the end of \s. In this example, we will split the target string at each white-space character using the \s special sequence. Now, let’s see how to use re.split() with the help of a simple example. Regex example to split a string into words However, the list contains just one element, the target string itself. If the specified pattern is not found inside the target string, then the string is not split in any way, but the split method still generates a list since this is the way it’s designed. It split the target string as per the regular expression pattern, and the matches are returned in the form of a list. Note: If capturing parentheses are used in the pattern, then the text of all groups in the pattern is also returned as part of the resulting list. For example, the re.I is used for performing case-insensitive searching. flags: By default, no flags are applied.If maxsplit is 2, at most two splits occur, and the remainder of the string is returned as the final element of the list. maxsplit: The number of splits you wanted to perform.string: The variable pointing to the target string (i.e., the string we want to split).pattern: the regular expression pattern used for splitting the target string.The regular expression pattern and target string are the mandatory arguments. Syntax re.split(pattern, string, maxsplit=0, flags=0) regex split()īefore moving further, let’s see the syntax of Python’s re.split() method.
