The split methods cut a string into parts based on the given separator parameter. With the optional second parameter we can control how many times the string is cut. str.split([sep[, maxsplit]]) Thestr.splitmethod returns a list of the words in the string, separated by the delimiter str...
Thestrip()method is useful when dealing with user input as it gets rid of surrounding spaces in the string. This means it doesn’t just remove spaces, it also removes tabs and new line characters, which are all characters we don’t usually want in user-provided strings. There are two mo...
