A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. Define a predicate isSorted that expects a list as an argument and returns True if the list is sorted, or returns False otherwise. (Hint: For a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return False if the first item in a pair is greater.)

Question
A list is sorted in ascending order if it is empty or each item except the last
one is less than or equal to its successor. Define a predicate isSorted
that expects a list as an argument and returns True if the list is sorted, or
returns False otherwise.
(Hint: For a list of length 2 or greater, loop through the list and compare
pairs of items, from left to right, and return False if the first item in a pair is
greater.)
Below is an example of a main function and the associated output:
def main():
lyst =
print(isSorted(lyst))
lyst = [1]
print(isSorted(lyst))
lyst = list(range(10))
print(isSorted(lyst))
lyst[9] = 3
print(isSorted(lyst))
