Simply just use len():

dic = {'val1':0,'val2':0,'val3':0}
length = len(dic)

never name your variables after built-ins or datatypes - like dict, list, set, tuple ... AND ... this ... is a set .... at least if you assing anything to the names `a,b,c` - else is is a `NameError`.. – Patrick Artner Mar 04 '18 at 21:58

@MrGenuis777 The variable is still called `dict` though – G_M Mar 04 '18 at 22:22

my_var = len(my_dict)

Gets the number of keys in the dictionary. Equivalent to len(my_dict.keys()).
