Apples<tab>round, fruity things oranges<tab>round, fruity things bananas<tab> without strip (), bananas is present in the dictionary but with an empty string as value With strip (), this code will throw an exception because it strips the tab of the banana line. 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 The method strip () returns a copy of the string in which all chars have been stripped from the beginning and the end of the string (default whitespace characters)
So, it trims whitespace from begining and end of a string if no input char is specified At this point, it just controls whether string x is empty or not without considering spaces because an empty string is interpreted as false in. 3 i think you mean a_list = [s.strip() for s in a_list] using a generator expression may be a better approach, like this Stripped_list = (s.strip() for s in a_list) offers the benefit of lazy evaluation, so the strip only runs when the given element, stripped, is needed. 3 just to add a few examples to jim's answer, according to.strip() docs Return a copy of the string with the leading and trailing characters removed
If omitted or none, the chars argument defaults to removing whitespace. The string.strip (), string.stripleading (), and string.striptrailing () methods trim white space [as determined by character.iswhitespace ()] off either the front, back, or both front and back of the targeted string /** * returns a string whose value is this string, with any leading and trailing * whitespace removed. 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. They both do the same thing, removing the symbols table completely
However, as @jimlewis pointed out strip allows finer control I'm trying to recreate the strip () function of python using regex It's the last practice problem from automate the boring stuff with python Import re stripchar = input ('enter 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
The with statement saves you from having to call close manually.
