Methods to Find a String in a List 1. Using theinOperator (Fastest for Membership Testing) Theinoperator is the most straightforward way to check if a string is present in a list. It is also the fastest method for membership testing, making it a great choice for simple checks. Here’s...
) S.split([sep [,maxsplit]]) -> list of strings #sep为分隔符,默认为空格 最大分隔次数 Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace ...
Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done, the rightmost ones. If sep is not specified or None, any whitespace string is a separator. Except for splitting from the right, rsplit() behaves like...
