stats = {'a':1000, 'b':3000, 'c': 100}
I'd like to get 'b' as an answer, since it's the key with a higher value.I did the following, using an intermediate list with reversed key-value tuples:
inverse =
print max(inverse)
Is that one the better (or even more elegant) approach?

fruits={
"apple":5,
"orange":7,
"mango":9
}
On reading the dictionary items, it should create 3 lists having same name as dictionary keys viz. apple, orange and mango and size of theses lists should be 5, 7 and 9 respectively. The elements of these lists should be given from the user through console.

mydict.update({'newkey':'newvalue'})
instead of

I don't teach this method and I don't know where they're finding examples of this, but I tell them not to do it because it's less efficient (presumably creates a new 2-element dict) and because it's nonstandard.
Honestly, I can understand the desire to use a visible method rather than this syntax - it perhaps feels more consistent with other method calls. But I think it looks like a newbie approach.
Is there any wisdom anyone has to offer on this point? less
