Write a function rotate(s,n) that has one string parameter s followed by a positive integer parameter n. It returns a rotated string such that the last n characters have been moved to the beginning. If the string is empty or a single character, the function should simply return the string unchanged. Assume that n is less than or equal to the length of s and that n is a positive intger. For example: rotate('abcdefgh',3) returns'fghabcde'

String has a method s.isdigit() that returns True if string s contains only digits and False otherwise, i.e. s is a string that represents an integer. Write a function named float_check that takes one parameter that is a string and returns True if the string represents a float and False otherwise. For the purpose of this function we define a float to be a string of digits that has at most one decimal point. Note that under this definition an integer argument will return True. Remember edge cases such as 45. or .45; both should return True. For example: float_check('1234') returns True float_check('123.45') returns True float_check('123.45.67') returns False float_check('34e46') returns False float_check('.45') returns True float_check('45.') returns True float_check('45..') returns False
