Dict KeyError for value in the dict

Question

I have a dict inside a dict:

{
\'123456789\': {u\'PhoneOwner\': u\'Bob\', \'Frequency\': 0},
\'98765431\': {u\'PhoneOwner\': u\'Sarah\', \'Frequency\': 0},
         


        

Answer 1

You are attempting to search for a key that is an integer:

phoneNumberDictionary[int(line)]

However, your dictionary is defined with your phone numbers as strings.

'123456789'

Thus, the key with integer 123456789 doesn't exist.
