我有一本字典词典,即dict[key1][key2]应该返回一个数字.如果我这样做key2 in dict[key1]返回True,但dict[key1].get(key2)返回None.
我想这里有一些非常基本的东西,但是我被卡住了.
由于key1是a string,而key2是a numpy.datetime64.
编辑:
key type: <type 'numpy.datetime64'>
key: 2014-08-11T02:00:00.000000+0200
Dict: {numpy.datetime64('2014-08-11T02:00:00.000000000+0200'): 1}
key in dict.keys() True
dict.items(): [(numpy.datetime64('2014-08-11T02:00:00.000000000+0200'), 1)]
dict.get(key): None

由编辑3取代
编辑3(替换编辑2):
码:
vessel = df['Vessel'].iloc[0]
print "vessel:",vessel
ati = np.datetime64(df['ATI'].iloc[0])
print "ati type:",type(ati),"value:",ati
print "Self.sailing[vessel]:",self.sailing[vessel]
print "key in dict.keys():",ati in self.sailing[vessel].keys()
sailing = self.sailing[vessel].get(ati)
print "sailing:", sailing
print "dict[key]:",self.sailing[vessel][ati]
输出:
vessel: VESSEL2
ati type: <type 'numpy.datetime64'> value: 2014-07-21T02:00:00.000000+0200
Self.sailing[vessel]: {numpy.datetime64('2014-07-21T02:00:00.000000000+0200'): …
