Test if dict contained in dict

Question

Testing for equality works fine like this for python dicts:

first  = {\"one\":\"un\", \"two\":\"deux\", \"three\":\"trois\"}
second = {\"one\":\"un\", \"two\         


        

Answer 1

all(k in second and second[k] == v for k, v in first.items())

if you know that none of the values can be None, it will simplify to:

all(second.get(k, None) == v for k, v in first.items())
