I want to put in a new dictionary named c all the keys that are in b
and re-sequence the values. The result I want is:
c={'a':0, 'c':1, 'd':2}
How can I do this with one line of instruction?
Why "one line"? Choosing the right data structure is far more important than squeezing the code to fit on one single line.
I'm not sure if I understand you correctly - or maybe you're confusing yourself. If you're going to "re-sequence" the values, the original values are not relevant at all; so maybe you need a list instead of a dict.
Perhaps this is what you want (something like swapping keys<->values): a = ['a', 'b', 'c', 'd'] b = ['a', 'c', 'd', 'e'] c = [x for x in a if x in b] c == ['a', 'c', 'd'] c[0] == 'a' c[1] == 'c' c[2] == 'd' -- Gabriel GenellinaSoftlab SRL
