Lstrip, rstrip and strip remove characters from the left, right and both ends of a string respectively By default they remove whitespace characters (space, tabs, linebreaks, etc) Map(str.strip, my_list) is the fastest way, it's just a little bit faster than comperhensions Use map or itertools.imap if there's a single function that you want to apply (like str.split) In short, i'd trust strip Maybe your application cannot be reduced any further without code changes.
They both do the same thing, removing the symbols table completely However, as @jimlewis pointed out strip allows finer control This is where my mind went since i like to strip whitespace earlier in my process flow and handle incoming data with variable headers (nans, ints, etc) Strip returns a new string, so you need to assign that to something (better yet, just use a list comprehension) iterating over a file object gives you lines, not words So instead you can read the whole thing then split on spaces
I was told it deletes whitespace but s = ss asdas vsadsafas asfasasgas print(s.strip()) prints out ss asdas vsadsafas asfasasgas shouldn't it be ssasdasvsadsafasasfasasgas? I know.strip() returns a copy of the string in which all chars have been stripped from the beginning and the end of the string But i wonder why / if it is necessary. How could you remove all characters that are not alphabetic from a string Does this have to be a custom function or are there also more generalizable solutions? I want to eliminate all the whitespace from a string, on both ends, and in between words
I have this python code Sentence = ' hello apple ' sentence.strip() but that Str.strip doesn't do what you think it does Str.strip removes any of the characters specified from the beginning and the end of the string So, acbacda.strip (ad) gives 'cbac' The a at the beginning and the da at the end were stripped
I am currently doing it in two instructions Import pandas as pd df = pd.dataframe([[' a ', 10], ['.
