Question

I have formed a dictionary with 2 keys assigning to a single dictionary value, for example:

my_dict[x, y] = ...
my_dict[a, u] = ...

Now how would i be able to use the has_key() method for 2 key variables, x and y like such:

if my_dict.has_key(x,y) == True:
    Do Something
else:
    Do something else

d is a matrix, that uses pdict values that i call from a variable f and g, but all you need to know is that they are variable names x,y being used as key values in pdict.

Answer 1

Since dict.has_key() has been deprecated for a long time now, you should use the in operator instead:

if (x, y) in my_dict:
    # whatever

Note that your dictionary does not have “two keys”. It probably uses a tuple of two elements as a key, but that tuple is a single object.
