从Python中重复模式的列表中移除重复字符

def remove_duplicates_using_set(lst):
    return list(set(lst))

# 示例
original_list = ['a', 'b', 'c', 'a', 'd', 'b']
unique_list = remove_duplicates_using_set(original_list)
print(unique_list)  # 输出: ['a', 'b', 'c', 'd'] 或其他顺序

def remove_duplicates_using_list_comprehension(lst):
    seen = set()
    return [x for x in lst if not (x in seen or seen.add(x))]

# 示例
original_list = ['a', 'b', 'c', 'a', 'd', 'b']
unique_list = remove_duplicates_using_list_comprehistic(original_list)
print(unique_list)  # 输出: ['a', 'b', 'c', 'd']

from collections import OrderedDict

def remove_duplicates_using_ordereddict(lst):
    return list(OrderedDict.fromkeys(lst).keys())

# 示例
original_list = ['a', 'b', 'c', 'a', 'd', 'b']
unique_list = remove_duplicates_using_ordereddict(original_list)
print(unique_list)  # 输出: ['a', 'b', 'c', 'd']
