So in the code and output above, you can see that by using the re.search() method, we have successfully found the substring between given two markers.Here we need to look for the string between two markers (; and /) in variable sampleStr. Extract Lets take a look: This method works fine when you have a small number of delimiters, but it quickly becomes messy when you have more than 2 or 3 delimiters that you would want to split your string by. First method we will be using to extract a given substring between two markers is by using the search() method of re module. The split() To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Here first off, we replace all occurrences of a semicolon followed by a space (; ) within the string with our other delimiter which is a comma followed by a space (, ). In re.split(), specify the regex pattern in the first parameter and the target character string in the second parameter. Whats unique about this method is that it allows you to use regular expressions to split our strings. Does Python have a string 'contains' substring method? The re.search(pattern) methods returns the string found which matches the given pattern. We and our partners use cookies to Store and/or access information on a device. Specify the maximum number of splits for the second parameter, maxsplit. It returns -1 if found nothing. find() method returns the position of string passed as argument or else returns -1.Finally slice the string with the positions.
