Python strings as sequences of characters. isalpha() Return true if all characters in the string are alphabetic and there is at least one character, false otherwise. Unicode characters are a representation of symbols, each character is given a unique code, so that you can use them anywhere, instead of having to copy paste everytime you want a symbol.
