ValueError: too many values to unpack in python

Error :-  

Traceback (most recent call last):

  File "<string>", line 25, in <module>

ValueError: too many values to unpack (expected 2)

> 

If you iterate the dictonary but missing items :- 

error code :- 

 for key,value in dictionary_test1:

        print(f"{key} is and value {value}")

solution code:- 

 for key,value in dictionary_test1.items():

        print(f"{key} is and value {value}")

Simply add the items() function in the last of the dictionary.
