In what version of Python?

In 2.1.1 I get an error trying that:
>>> map([str, str, lambda x: x * 3], [1, 2, 3])
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: object of type 'list' is not callable

I guess you meant map(lambda x, y: x(y), converters, fields), and I
agree that would be better.  I'm quite surprised to find that lambda
x, y: x(y) doesn't have a name in the operator module; 'apply' is
almost right, but not quite.

The listcomp equivalent would be
[x(y) for x, y in zip(converters, fields)]
and I think that's even better.
