Find key based length of values in dict

Question

I have dict like follows:

a = {'abc':[0,1,2], 'def':[0,1,2,3,4], 'ghi':[0,1,2,3,4,5]}

Want to get the key based on the max length of the array contains. As in here, out put would be 'ghi'. Anybody how to do it. I have tried:

lambda x: max(len(x[1])), a.items() but it doesn't solve the purpose. Can anyone tell what should I do?

Answer 1

Try:

max(a, key=lambda x: len(a[x]))

Answer 2

try this:

a = {'abc':[0,1,2], 'def':[0,1,2,3,4], 'ghi':[0,1,2,3,4,5]}

print(list(a.keys())[list(a.values()).index(max(a.values()))])
