Need help developing code in python. Objective is to formulate these functions denoted by each part. I want to these functions (parts) to operate in the same series of lines of code.

Part A

Write a function named leap_year that takes one string parameter. It returns True if the string represents a leap year, and returns False otherwise.

For example, 1896, 1904, and 2000 are leap years, but 1900 is not. Therefore, leap_year(1896) returns True.

Part B: Rotate

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'

Part C: Digit Count

Write a function named digit_count that takes one parameter that is a number (int or float) and returns a count of even digits, a count of odd digits, and a count of zeros that are to the left of the decimal point. Return the three counts in that order: even_count, odd_count, zero_count.

For example:

digit_count(1234567890123) returns (5, 7, 1)

digit_count(123400.345) returns (2, 2, 2)

print(digit_count(123.)) returns (1, 2, 0)

print(digit_count(.123)) returns (0, 0, 0)

Part D: Float Check

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

again, I need help creating correct codes for each of the parts described above. Once correct codes have been created, the functions must be implemented in the same python suite.
