Question

I want to do something like:

all = [ x for x in t[1] for t in tests ]

tests looks like:

[ ("foo",[a,b,c]), ("bar",[d,e,f]) ]

So I want to have the result

all = [a,b,c,d,e,f]

My code does not work, Python says:

UnboundLocalError: local variable 't' referenced before assignment

Is there any simple way to do that?

Answer 1

It should work the other way around:

all = [x for t in tests for x in t[1]]
