Problems with double .get() in dictionary-CodePudding

I'm working with a nested dictionary were the entries looks like this:

net_info = {
            '17052242':{'lengthkm': 1.555787, 'uparea': 123.23709555834532, 'order': 2,
                        'strmDrop_t': 231.5, 'unitarea': 123.23709555834532},
            '21009006':{'lengthkm': 6.677901703662528,'uparea': 493.8188826654188,
                        'order': 2,'strmDrop_t': 5.3, 'unitarea': 36.89608111068623},
            .
            .
            .
             }

Here is a line of code where I look for a key and a feature inside the dictionary using a double .get(). It works like a charm except when it can't find the key... I know it is because it is passing 0 as a key to the next .get(). My question is, is there a way to just return 0 if it can't find the key and not pass it to the next .get()?

unitarea_max = max(net_dictionary.get(in1,0).get('unitarea',0), \
net_dictionary.get(in2,0).get('unitarea',0))

CodePudding user response：

You need to pass a dictionary to the next .get(). Since it's an empty dictionary you'll get the default from the second .get().

net_dictionary.get(in1,{}).get('unitarea',0)
