Strings in Python String Traversal
Traversing a string • Traversing just means to process every character in a string, usually from left end to right end • Python allows for 2 ways to do this – both useful but not identical • if all you need is the value of each character in the string for ch in stringvar: will work fine. ch is given the value of each character from left to right, and can be used in the for loop as you need • The other way uses the location of the characters in the string for ct in range(len(stringvar)): makes the variable ct an integer which has all the values of the subscripts of the characters in the string. If it is important that you know where a character is, this is the form you use.
