[Tutor] deleting elements of a dictionary

I am trying to remove incorrect entries of my dictionary.
I have multiple keys for the same value,


and I have found out that some key:value pairs are incorrect, and the best
thing to do
is to delete all entries who value is 5. So this is what I am doing:

import numpy
read_dictionary = numpy.load('loc_string_dictionary.npy').item()

for n in read_dictionary:
    if read_dictionary[n] == '5':
        del read_dictionary[n]

However, I get this error:
RuntimeError: dictionary changed size during iteration

and I can see why.

What's the better thing to do?
