removing dictionary key-pair

[JD]

Hello,

I try to remove a dictionary key-pair (remove an entry),
but I'm unsuccessful. Does anyone know how to achieve this?

Thanks

mydict = {"key" : "value"}
del mydict(key)

Assuming you know the key:

d = {"foo":1,"bar": 2}
print d
del(d["foo"])
print d

d = dict(a=1, b=2, c=3)

print d

del d['a']

print d
