How to get multiple dictionary values?

I have a dictionary in Python, and what I want to do is get some values from it as a list, but I don't know if this is supported by the implementation.

myDictionary.get('firstKey')   # works fine

myDictionary.get('firstKey','secondKey')
# gives me a KeyError -> OK, get is not defined for multiple keys
myDictionary['firstKey','secondKey']   # doesn't work either

Is there any way I can achieve this? In my example it looks easy, but let's say I have a dictionary of 20 entries, and I want to get 5 keys. Is there any other way than doing the following?

myDictionary.get('firstKey')
myDictionary.get('secondKey')
myDictionary.get('thirdKey')
myDictionary.get('fourthKey')
myDictionary.get('fifthKey')
Solution

  • Use a for loop:

    keys = ['firstKey', 'secondKey', 'thirdKey']
for key in keys:
    myDictionary.get(key)

    or a list comprehension:

    [myDictionary.get(key) for key in keys]
