See Fredrik's post. There's no error in the expression with map(),
it's just less effecti

list comprehensions are more efficient than map/lambda combinations;
the above is better written as:
lst = [x.strip() for x in lst]
in general, map() works best when the callable is an existing function
(especially if it's a built-in).

__revision__ = "test_mod 0.1 by TV 06/10/22"
lst = ['aaa', ' bbb', '\tccc\n']
lst = map(lambda x: x.strip(), lst)
result = """
