如何检查列表中的python字典值中是否存在元素？

Question

How to check whether '111' exists in dic1 ?

dic1 = {'images':[000,111,222,333,444],'name':['foo','bar','baz']}

I tried using List comprehensions but unable to get the boolean answer? I got the error 'int' object is not iterable .

Answer 1

You can iterate over dict.values and check for existence:

dic1 = {'images':[000,111,222,333,444],'name':['foo','bar','baz']}
print(any(111 in b for b in dic1.values()))

Output:

True
