Is it possible to get all keys in a dictionary with values above a threshold?
A dictionary could look like:
mydict = {(0,1,2): "16", (2,3,4): "19"}
The threshold could be 17 for example.
Of course it is possible. We can simply write:
[k for k,v in mydict.items() if float(v) >= 17]
Or in the case you work with python-2.7, you - like @NoticeMeSenpai says - better use:
[k for k,v in mydict.iteritems() if float(v) >= 17]
This is a list comprehension. We iterate through the key-value pairs in the mydict dictionary. Next we convert the value v into a float(v) and check if that float is greater than or equal to 17. If that is the case, we add the key k to the list.
For your given mydict, this generates:
>>> [k for k,v in mydict.items() if float(v) >= 17]
[(2, 3, 4)]
So a list containing the single key that satisfied the condition here: (2,3,4).
