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.
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.
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.
split() relies on white-space as the separator, so it will fail to separate hyphenated words--and long-dash separated phrases will fail to split too. And if the sentence contains any punctuation without spaces, those will fail to stick. For any real-world text parsing (like for this comment), your nltk suggestion is much better than split()`. –
Dec 15, 2009 · Joining a string with ' ' just adds spaces in between for the .split, so this is just a convoluted way to make a list of the characters (list(str(a)) is much simpler) and more direct) - but there is also no reason to create that intermediate list anyway, since the string is already iterable.
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.
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 ...
>>> tmp = "a,b,cde" >>> ''.join(tmp.split(',')[::-1]) 'cdeba' The important parts here are the split function and the join function . To reverse the list you can use reverse() , which reverses the list in place or the slicing syntax [::-1] which returns a new, reversed list.
Oct 1, 2015 · Steps: Create a new string to keep track of the current word (word) and a new list to keep track of the words in this string (sentence_list). If you come across the character (s) you want to split on (spaces in this example), check that word is not empty and add it to sentence_list, otherwise add the character to word.
Sep 8, 2020 · 3. John, Mr. Johnson. Mr. Where the expand=True renders a set of columns of strings. Therefore, after the first split, you may apply again another str.split method since the first split has rendered dataframe of strings as columns. This would have been a little more complicated with a regular split (or expand=False) which renders a series of lists.
