如何从“collections.defaultdict”中删除项目？

Question

I have a collections.defaultdict as follows:

mydict = defaultdict(lambda:0)
mydict['stock1'] = 1.11
mydict['stock2'] = 2.22
mydict['stock3'] = 3.33

Now I want to remove the second item completely, how can I do that?

Maybe there is little seens to remove that but just simply set it to zero as follow:

mydict['stock2'] = 0

See the documentation , it's just like the ordinary dictionary. You can use either:

• del mydict['stock2']
• mydict.pop('stock2')
