Question

我使用下面的代码获得了意想不到的结果。我试图更新字典中包含的列表。我在Windows 10上使用python 3.6.4。

discovery = {'interface': {}}

interface_sch = {
                    'type':'',
                    'etherchannel':'',
                    'description':'',
                    'tagged':[],
                    'untagged':'',
                    'ipaddress':'',
                    'portstate':'',
                    'linkstate':'',
                    'speed':'',
                    'remotedevice':'',
                    'remotedeviceport':'',
                    }

#Populate {interface:} key(1/1 - 1/48)
for port in range(1,49):
    port=str(port)
    discovery['interface']["1/" + port]=interface_sch


#Populate port tag list.
for tag in ['1','2','10','20']:
    for port in ['1/1','1/3','1/5','1/10']:
        discovery['interface'][port]['tagged'].append(tag)



#Sample one of the interfaces from the dictionary
print(discovery['interface']['1/3']['tagged'])

为什么我的结果？ [＆＃39; 1＆＃39;，＆＃39; 1＆＃39;，＆＃39; 1＆＃39;，＆＃39; 1＆＃39;，＆＃39; 2＆＃39;，＆＃39; 2＆＃39;，＆＃39; 2＆＃39;，＆＃39; 2＆＃39;，＆＃39; 10＆＃39;，＆＃39; 10＆＃39;，＆＃39; 10＆＃39;， ＆＃39; 10＆＃39;，＆＃39; 20＆＃39;，＆＃39; 20＆＃39;，＆＃39; 20＆＃39;，＆＃39; 20＆＃39;]
