The left edge of the first character in the string is numbered 0. We can slice from this location with the index i. The right edge of the last character of a string of n characters has the index n. We can slice from this location with the index j. For example:Python Copy ...
Python之String Methods Here are some of the most common string methods. A method is like a function, but it runs "on" an object. If the variable s is a string, then the code s.lower() runs the lower() method on that string object and returns the result (this idea of a method ...
