i have a dictionary containing the following lists:

```
data = {'A': [194.0, 78.0, 75.0],
        'H': [74.0, 211.0, 101.0],
        'L': [75.0, 99.0, 111.0],
        'Z': [193.0, 75.0, 74.0],
        'X': [61.0, 124.0, 66.0],
        'Y': [44.0, 81.0, 52.0]}

```

The number of keys changes, but the number of entries inside each list does not. I need get the key of the row with the biggest number in each column, so I can write a file containing [A,H,L].

I can't think of a way that doesent involve rebuilding the dictionary as a list of lists, or jumping into pandas. I was wondering if there's a pythonic way of solving it the way it is.

Thanks
