Python dict快速获得价值

Question

Is this the best way to get the value/key of someID .

I want to separate the keys and values I receive:

items={'someID': 2,}
for item in items:
    key = item
    print(key)
    value = items.get(item)
    print(value)

This works, but is this the correct/fastest way in Python 3.4?

Answer 1

You can use the items() method to iterate over the keys and values.

d = {1:2, 3:4, 5:6}
for key, value in d.items():
    print(key, value)

Answer 2

Better is

for key, value in items.items():
   print (key)
   print (value)

Then you don't need getting values
