将列表合并为字典 与 用set去重后使表内元素顺序不变

将两个列表合并为字典

names = ['lilu', 'lucy']

likes = ['swimming', 'eating']

a = dict(zip(names,likes))

print(a)

#{'lilu': 'swimming', 'lucy': 'eating'}

用set去重后使表内元素顺序不变

L = [1, 8, 4, 5, 2, 9, 3, 1, 4, 5]
L1 = list(set(L)) # 去重但顺序可能改变了 [1, 2, 3, 4, 5, 8, 9]
print(L1)
L1.sort(key=L.index) # 将顺序变为与元列表相同
print(L1)   # [1, 8, 4, 5, 2, 9, 3]
