As long as you stay in the domain of the common characters, there is little practical difference between ASCII and Unicode. s.isalnum() returns True if s is nonempty and all its characters are alphanumeric (either a letter or a number), and False otherwise: Determines whether the target string consists of alphabetic characters. Find centralized, trusted content and collaborate around the technologies you use most. -1 refers to the last character, -2 the second-to-last, and so on, just as with simple indexing. def shift_on_character(string, char): try: pos = string.index(char) return string[pos:] + string[:pos] except IndexError: # what do you want to do if char is not in string?? An escape character is a backslash \ followed by the character you want to insert. note that this only applies to Python 2 which is hopefully a shrinking minority now, Iterating each character in a string using Python, How Intuit democratizes AI development across teams through reusability. and what would happen then? bytearray objects are very like bytes objects, despite some differences: There is no dedicated syntax built into Python for defining a bytearray literal, like the 'b' prefix that may be used to define a bytes object.
