Hello,

A code example from the 'functional programming how-to' raises an error.

The simplest fix would be to remove the Ellipsis object from the 'line_list'.

Thank you,
Diogo

Please check below for the commands issued:

# https://docs.python.org/3/howto/functional.html#generator-expressions-and-list-comprehensions

>>> line_list = ['  line 1\n', 'line 2  \n', ...]
>>> 
>>> # Generator expression -- returns iterator
>>> stripped_iter = (line.strip() for line in line_list)
>>> 
>>> # List comprehension -- returns list
>>> stripped_list = [line.strip() for line in line_list]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 1, in <listcomp>
AttributeError: 'ellipsis' object has no attribute 'strip'
