Python result of a strange function, that I can't reproduce in another language

Question

My python function :

def searchMAX(Dict):
    v=list(Dict.values())
    return list(Dict.keys())[v.index(max(v))]

I can't reproduce it in java to understand what's its output

If I do :

myDico ={0:0.0}
myDico.update({1:1.2}) 
myDico.update({2:11.2}) 
myDico.update({3:17.2})
myMax = searchMAX(myDico)
print(*myMax, sep='\n')

I have this error :

TypeError: print() argument after * must be an iterable, not int

With print(myMax, sep'\\n') only retun 3 not a list :( ?

Answer 1

Assuming that Dict is a Python dict then:

v = list(Dict.values())

make a list of the iterator over the values of Dict and assings it to v

Then

return list(Dict.keys())[v.index(max(v))]

make a list of the keys of Dict and and returns the key that has the maximum value associated with it by finding the index of the maximum value ( v.index(max(v)) ) and using that index on the list.

Thus searchMAX return a key which in your case is always an integer and you cannot pass that to print() with a * . You should do:

print(Max, sep='\n')
