By default they remove whitespace characters (space, tabs, linebreaks, etc) 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 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? 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
The chars argument is a string specifying the set of characters to be 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. 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
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. 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 The with statement saves you from having to call close manually.
List = map(str.strip, list) this will apply the function str.strip to every element in list, return a new list, and store the result back in list. 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.
