Dictionary adds an unexpected list - erina - Mar-14-2019
Hello,
my expected output is :
data={'Switchboard1':[{'Light':[1,2,3,4],'Fan':[1,2,3,4]}]}
But when the code executes the underlined point it adds the key "switchboard" to dic1,eventhough I initialize dic1 only with "delta".
delta=[1,2,3,4]
dic1=dic2={}
data={'Switchboard1':['Light','Fan']}
home= data.keys()
for k, v in data.iteritems():
for i in v:
dic1[i]=delta
print dic1,k
[u]dic2[k]=dic1[/u]
print dic1
print dic2
dic1=dic2={}

Because of line 2, dic1 and dic2 are the same dict. Any changes you make to one are made to the other. Use this instead:
dic1, dic2 = {}, {}
