为什么在Python中list.sort()不会返回已排序的列表？

# Creating a List
myList = ["Jacob", "Harry", "Mark", "Anthony"]

# Displaying the List
print("List = ",myList)

# Sort the Lists in Ascending Order
myList.sort()

# Display the sorted List
print("Sort (Ascending Order) = ",myList)

List =  ['Jacob', 'Harry', 'Mark', 'Anthony']
Sort (Ascending Order) =  ['Anthony', 'Harry', 'Jacob', 'Mark']

# List of dictionaries
d = [
   {"name" : "Sam", "marks" : 98},
   {"name" : "Tom", "marks" : 93},
   {"name" : "Jacob", "marks" : 97}
]

# Display the Dictionary
print("Dictionary = \n",d)

# Sorting using values with the lambda function
print("Sorted = \n",sorted(d, key = lambda item: item['marks']))

('Dictionary = \n', [{'name': 'Sam', 'marks': 98}, {'name': 'Tom', 'marks': 93}, {'name': 'Jacob', 'marks': 97}])
('Sorted = \n', [{'name': 'Tom', 'marks': 93}, {'name': 'Jacob', 'marks': 97}, {'name': 'Sam', 'marks': 98}])
