A dict object has a number of member
methods. Many of these maintain the values in a
dict. Others retrieve parts of the
dict as a sequence, for use in a
for statement. In the following definitions,
d is a dict
object.
The following transformation functions update a
dict object.
d.clear
Remove all items from the
dict.
d.copy
→ dictionary
Copy the dict to make a new
dict. This is a shallow
copy. All objects in the new
dict are references to the same objects as
the original dict.
d.setdefault(key,
[default]) → object
Similar to d.get(key ) and
d[key] - get the
item with the given key. However, this sets a default value to the
supplied object.
d.update(new,
[default]) → object
Merge values from the new dict into
the original dict, adding or replacing as
needed. It is equivalent to the following Python statement.
for k in new.keys(): d[k]= new[k]
d.pop(key,
[value]) → object
Remove the given key from the dict,
returning the associated value. If the key does not exist, return
the optional value provided in the pop
call.
The following accessor methods provide information about a
dict.
d.get(key,
[default]) → object
Get the item with the given key,
similar to
d[key].
If the key is not present, supply default
instead.
d.has_key(key)
→ boolean
If there is an entry in the dict with
the given key, return
True, otherwise return
False.
d.items
→ sequence
Return all of the items in the dict
as a sequence of (key,value) tuples. Note
that these are returned in no particular order.
d.keys
→ sequence
Return all of the keys in the dict as
a sequence of keys. Note that these are returned in no particular
order.
d.values
→ sequence
Return all the values from the dict
as a sequence. Note that these are returned in no particular
order.
