I'm trying to do the second exercise in the Lists section of the book "How to Think Like a Computer Scientist". I basically have to match the given "doctest" with a program of my own that returns no error. I tried several ways, but despite the fact that the "Got" matches the "Expected" perfectly, it keeps giving me 1 failure.
I already saw one question here that asked "How can python 2 doctest fail and yet have no difference in values in the failure message?" I tried a few of the solutions given, like changing the test to "raw" by putting the r before it, but I don't think that the answer matches my case, because I checked several times after seeing this question and there isn´t a visible extra space where the problem seems to be.
This is the test I'm supposed to match:
"""
>>> b_list[1:]
['Stills', 'Nash']
>>> group = b_list + c_list
>>> group[-1]
'Young'
"""
And this is the program I wrote:
# Add your doctests here:
"""
>>> b_list[1:]
['Stills', 'Nash']
>>> group = b_list + c_list
>>> group[-1]
'Young'
"""
#Write your python code here:
b_list = ['a', 'Stills', 'Nash']
b_list[1:]
c_list = ['Young']
group = b_list + c_list
group[-1]
if __name__ == '__main__':
import doctest
doctest.testmod()
And this is the test result:
File ".\ch902.py", line 3, in __main__
Failed example:
b_list[1:]
Expected:
['Stills', 'Nash']
Got:
['Stills', 'Nash']

1 items had failures:
1 of 3 in __main__
***Test Failed*** 1 failures.
