8. You need to use re.split if you want to split a string according to a regex pattern. tokens = re.split(r'[.:]', ip) Inside a character class | matches a literal | symbol and note that [.:] matches a dot or colon (| won't do the orring here). So you need to remove | from the character class or otherwise it would do splitting according to the ...
Here is a simple .split solution that works without regex.. This is an answer for Python split() without removing the delimiter, so not exactly what the original post asks but the other question was closed as a duplicate for this one.
Using split() will be the most Pythonic way of splitting on a string. It's also useful to remember that if you use split() on a string that does not have a whitespace then that string will be returned to you in a list. Example: >>> "ark".split() ['ark'] edited Feb 21, 2017 at 14:25. answered Feb 21, 2017 at 14:18.
Also you're calling split() an extra time on each string. Get rid of those and a solution using split() beats the regex hands down on shorter strings and comes a pretty close second on the longer one.
Since this question is tagged with regex, I decided to try a regex approach. I first replace all the spaces in the quotes parts with \x00, then split by spaces, then replace the \x00 back to spaces in each part. Both versions do the same thing, but splitter is a bit more readable then splitter2. def replacer(m):
here is a simple function to seperate multiple words and numbers from a string of any length, the re method only seperates first two words and numbers. I think this will help everyone else in the future, def seperate_string_number(string): previous_character = string[0]
return re.split(regex_pattern, string, maxsplit) If you're going to split often using the same delimiters, compile your regular expression beforehand like described and use RegexObject.split. If you'd like to leave the original delimiters in the string, you can change the regex to use a lookbehind assertion instead: >>> import re.
Python split a string then regex. 1. Regex in python splitting strings. 0. Split a string with RegEx. Hot ...
This will split at every space that is followed by a string of upper-case letters which end in a word-boundary. Note that the square brackets are only for readability and could as well be omitted. If it is enough that the first letter of a word is upper case (so if you would want to split in front of Hello as well) it gets even easier:
What is the pythonic way to split a string before the occurrences of a given set of characters? For example, I want to split 'TheLongAndWindingRoad' at any occurrence of an uppercase letter (possibly except the first), and obtain ['The', 'Long', 'And', 'Winding', 'Road'] .
