I can't help with that specifically but...

lambdas are intended for anonymous functions so if you
are not going to pass the lambda expression directly
but assign it to a name, then it would be better to take
the definition outside the loop and only do it once.

def y(x): return ''.join([x.split()[3],x.split()[-3],x.split()[-6]])
for x in csvr:
      csvw.write(y)

But I can't answer this bit, sorry.
