When you want to split a string by a specific delimiter like: __ or | or , etc. it's much easier and faster to split using .split() method as in the top answer because Python string methods are intuitive and optimized. However, if you need to split a string using a pattern (e.g. " __ " and "__"), then using the built-in re module might be useful.
Feb 12, 2011 · The big plus is that it works the same in both Python 2 and Python 3. Also, starting from Python 3.5 (thanks to the awesome PEP 448) it's now possible to build a list from any iterable by unpacking it to an empty list literal: >>> [*'abc'] ['a', 'b', 'c'] This is neater, and in some cases more efficient than calling list constructor directly.
Dec 4, 2016 · 1. It splits the string into items of a list. For example. 'I am a string'.split(' ') Gives the output. ['I', 'am', 'a', 'string'] Explanation: Here, I used ' ' as a split so every time a ' ' character comes, it splits the string into a new item of list. edited Jul 3, 2020 at 0:16.
Nice, but some English words truly contain trailing punctuation. For example, the trailing dots in e.g. and Mrs., and the trailing apostrophe in the possessive frogs' (as in frogs' legs) are part of the word, but will be stripped by this algorithm.
Jun 15, 2012 · 2. Using regex is probably the best way to do this: import re. re.split('\s+|:-','Breathing 1:-135') This gives you ['Breathing', '1', '135'], which is exactly what you want. Here, the \s+ stands for one or more whitespaces, the | stands for "or", and :- is matched literally.
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. def splitkeep(s, delimiter): split = s.split(delimiter) return [substr + delimiter for substr in split[:-1]] + [split[-1]] Random tests:
Aug 3, 2015 · 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.
So i.split ('\t', 1) calls the split () method of strings. Per the documentation, the first parameter of this method is the string to split by and the second is the maximum number of splits to perform. The method returns the list of strings that result from performing the split, so " [0]" returns the first split string in the result list. When ...
Jan 15, 2018 · 12. If you want to split a string into more than two columns based on a delimiter you can omit the 'maximum splits' parameter. You can use: df['column_name'].str.split('/', expand=True) This will automatically create as many columns as the maximum number of fields included in any of your initial strings.
Dec 13, 2022 · The difference between split and rsplit is pronounced only if the maxsplit parameter is given. In this case the function split returns at most maxsplit splits from the left while rsplit returns at most maxsplit splits from the right. Both functions work on python string (str) type, and their signatures are:
