consider iterating the dictionary directly instead of calling .keys() code example
Example 1: python loop through dictionary
dictionary = {52:"E",126:"A",134:"B",188:"C",189:"D"}
for key, value in dictionary.items():
print(key)
print(value)
Example 2: python loop through dictionary
new_list = [something(key, value) for key, value in a_dict.items()]
