'dict' object has no attribute 'key'

The error message you encountered suggests that you are trying to access the attribute 'key' on a dictionary object, but it doesn't exist. It's likely that you made a typographical error and meant to use the attribute 'keys' instead. The 'keys' attribute returns a view object that contains all the keys in the dictionary. You can iterate over it or convert it to a list using the 'list()' function. Here's an example:

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
keys = my_dict.keys()
print(list(keys))  # ['key1', 'key2', 'key3']

Make sure to double-check your code and verify that you are using the correct attribute name.
