1The max() function returns the largest of the input values.

7  PARAMETER	       			     DESCRIPTION
8  iterable    | An iterable object like string, list, tuple etc.
9 (required)	
10  default     | The default value to return if the iterable is empty.

13 (optional)     order. The function is applied to each item on the iterable.

16Example:
17 max([2, 1, 4, 3]) # Output: 4
18 max([], default=0) # supressing the error with default value, Output: 0
19 max("c", "b", "a", "Y", "Z") # Output: c
20 max("c", "b", "a", "Y", "Z", key=str.lower) # Output: Z
