My question:
I don’t know what the problem is with this code? I have 4 dictionaries in a list. I want to traverse the list once, then traverse the name key of the dictionary again in the traversal result, and then print the value of the name key. Why can't it be printed?

Answer 1

keys

Answer 2

1. First of all, it is keys, not key
2. Secondly, for can traverse the dictionary directly without calling kes()

Answer 3

The first floor is highlighted. Keys are the attributes of dict. The error "Dictionary object does not have an attribute called 'key'" has already explained the problem. At this time, you can find the answer by checking the dict index in the Python documentation.
