Another dict method...

Anyone who sees the use of a dict.peekitem() which works
like dict.popitem() but doesn't actually remove an item
from the dictionary? Could be useful for things like
this (cf. earlier post about minimum of dict):

def key_with_minimum_value(dict):
    k1, v1 = dict.peekitem()
    for k2, v2 in dict.iteritems():
        if v2 < v1:
            k1, v1 = k2, v2
    return k1

Just a thought. The following seems a bit ... odd:

    k1, v1 = dict.popitem() # Get an item
    dict[k1] = v1           # Put it back
