我有一本字典和一份清单:
dct = {'A': a1, 'B': b2}
a1 = [0, 2, 4, 6, 8]
b2 = [1, 3, 5, 7, 9]
在此基础上制定清单:
c = [2, 8, 5]
你怎么回到字典键?要使c
列表显示为:
c2 = [AAB]

您可以构建从列表中的值到字典键的附加映射,然后使用它来查找列表<form autoComplete="new-password" ... >
<input name="myInput" type="text" autoComplete="off" id="myInput" placeholder="Search field" />
</form>
中值的键:
c

迭代方法:
a1 = [0, 2, 4, 6, 8]
b2 = [1, 3, 5, 7, 9]
dct = {'A': a1, 'B': b2}
c = [2, 8, 5]
result = ''
for i in c:
for k, v in dct.items():
if i in v:
result += k
break
print(result) # AAB
答案 2 :(得分:0)
对象/字典 有一个名为.viewkeys()的方法
试 dct = {&#39; A&#39;:&#39; a1&#39;,&#39; B&#39;:&#39; b2&#39;} 打印(dct.viewkeys())
