Biggest value of (not all) dictionary keys in Python

Question

What's the best way to get the biggest value of only the keys x, y, w and z in the dictionary above using Python?

my_dict = {"a":0, "b":5, "c":3, "x":4, "y":3, "w":2, "z": 1}

Thanks

Answer 1

You can try this:

my_dict = {"a":0, "b":5, "c":3, "x":4, "y":3, "w":2, "z": 1}
print(max(my_dict[i] for i in ["x", "y", "w", "z"]))

Output:

4

Answer 2

You could create a temporary dictionary to hold your values, then search in this dictionary for the value you want.

my_dict = {"a":0,"b":5,"c":3,"x":4, "y":3, "w":2, "z": 1}
newdict = {key:my_dict[key] for key in ['x', 'y','w','z']}
print(newdict[max(newdict, key=newdict.get)])
