I assume your talking about building a new dictionary with the key and
value pair switched. I have seen no built in function to do this but I
have found a way to create another dictionary that is the inverse of
the first.
for example you have designed a dictionary such as
a={}
a['one']=1
a['two']=2
a['three']=3
a['four']=4
when your redy to build a revers dictionary you semply do the folowing
b={}
for x in a:
temp_idx=a[x]
b[temp_idx]=x
now you get
{'four': 4, 'three': 3, 'two': 2, 'one': 1}
for a
and
{1: 'one', 2: 'two', 3: 'three', 4: 'four'}
for b
