Python中如何删除列表中的重复项？

from collections import OrderedDict

# Creating a List with duplicate items
mylist = ["Jacob", "Harry", "Mark", "Anthony", "Harry", "Anthony"]

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

# Remove duplicates from a list using dictionary
resList = OrderedDict.fromkeys(mylist)

# Display the List after removing duplicates
print("Updated List = ",list(resList))

# Creating a List with duplicate items
mylist = ["Jacob", "Harry", "Mark", "Anthony", "Harry", "Anthony"]

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

# Remove duplicates from a list using List Comprehension
resList = []
[resList.append(n) for n in mylist if n not in resList]
print("Updated List = ",resList)

# Creating a List with duplicate items
mylist = ["Jacob", "Harry", "Mark", "Anthony", "Harry", "Anthony"]

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

# Remove duplicates from a list using Set
resList = set(mylist)
print("Updated List = ",list(resList))

List =  ['Jacob', 'Harry', 'Mark', 'Anthony', 'Harry', 'Anthony']
Updated List =  ['Anthony', 'Mark', 'Jacob', 'Harry']
