[PYTHON] Dictionary items method

`items.py`


num = {'x':100, 'y':200}
print(num.items())

#When processing the dictionary with a for statement, the key is returned
for k in num:
    print(k)
    
#If you want values, use the values method
for v in num.values():
    print(v)

#If you want a key / value pair, use the items method
#When processed with a for statement, k,Each v contains a key and a value(Tuple unpacking)
for k, v in num.items():
    print(k, ':', v)

Output result:

dict_items([('x', 100), ('y', 200)])
