A KeyError
generally means the key doesn’t exist. So, are you sure the path
key exists?
From the official python docs:
exception KeyError
Raised when a mapping (dictionary) key is not found in the set of existing keys.
For example:
>>> mydict = {'a':'1','b':'2'} >>> mydict['a'] '1' >>> mydict['c'] Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: 'c' >>>
So, try to print the content of meta_entry
and check whether path
exists or not.
>>> mydict = {'a':'1','b':'2'} >>> print mydict {'a': '1', 'b': '2'}
Or, you can do:
>>> 'a' in mydict True >>> 'c' in mydict False
