如何从列表中快速获取唯一的单词？

# 假设我们有一个包含重复单词的列表
words = ["apple", "banana", "apple", "orange", "banana", "grape"]

# 使用集合去重
unique_words = set(words)

# 将集合转换回列表
unique_words_list = list(unique_words)

print(unique_words_list)

['banana', 'grape', 'orange', 'apple']

from collections import OrderedDict

words = ["apple", "banana", "apple", "orange", "banana", "grape"]
unique_words_ordered = list(OrderedDict.fromkeys(words))

print(unique_words_ordered)

['apple', 'banana', 'orange', 'grape']

words = ["Apple", "banana", "apple", "Orange", "banana", "grape"]
unique_words_case_insensitive = list(set(word.lower() for word in words))

print(unique_words_case_insensitive)

['banana', 'grape', 'orange', 'apple']
