No, because that's asking for the answer :) What you need to do is look at the failing test cases, and figure out why your function is giving the wrong result. Do you see what's true of all the failing cases and is not true of any others? That might give you a clue as to what's wrong.

ChrisA This Is My Code(using Python 2.7) Its working fine with the given test cases. #Lucky_Sum a =[] def lucky_sum(list): t = 0 for item in list: if item == 13: break else: t=t+item return t list=[] type(list) n = raw_input(Enter Numebr of item in list: ) n = int(n) for x in range (0,n): list.append(int(raw_input())) print List is :,list print lucky_sum(list) -- https://mail.python.org/mailman/listinfo/python-list
codingbat question broken?
I'm working on the following problem set from codingbat.com http://codingbat.com/prob/p107863 Given 3 int values, a b c, return their sum. However, if one of the values is 13 then it does not count towards the sum and values to its right do not count. So for example, if b is 13, then both b and c do not count. lucky_sum(1, 2, 3) → 6 lucky_sum(1, 2, 13) → 3 lucky_sum(1, 13, 3) → 1 The solution I came up with was - def lucky_sum(a, b, c): t = 0 for ints in (a, b, c): if a == 13: t = b + c elif b == 13: t = a elif c == 13: t = a + b else: t = a + b + c return t However the following tests fail lucky_sum(13, 2, 3) → 05X lucky_sum(13, 2, 13) → 015Xlucky_sum(13, 13, 2) → 015X Can anyone show me an example where all test are success? -- https://mail.python.org/mailman/listinfo/python-list

This runs on 2.7 or 3.4, unmodified (other than the #!):
#!/usr/local/cpython-2.7/bin/python
#!/usr/local/cpython-3.4/bin/python
def lucky_sum(*list_):
lucky_total = 0
for element in list_:
if element == 13:
break
lucky_total += element
return lucky_total
if __name__ == '__main__':
print('starting tests')
assert lucky_sum(1, 2, 3) == 6
assert lucky_sum(1, 2, 13) == 3
assert lucky_sum(1, 13, 3) == 1
print('ending tests')

Given 3 int values, a b c, return their sum. However, if one of the values
is 13 then it does not count towards the sum and values to its right do not
count. So for example, if b is 13, then both b and c do not count.
lucky_sum(1, 2, 3) → 6
lucky_sum(1, 2, 13) → 3
lucky_sum(1, 13, 3) → 1
The solution I came up with was -
def lucky_sum(a, b, c):
t = 0
for ints in (a, b, c):
if a == 13:
t = b + c
elif b == 13:
t = a
elif c == 13:
t = a + b
else:
t = a + b + c
return t
However the following tests fail
lucky_sum(13, 2, 3) → 05X lucky_sum(13, 2, 13) → 015Xlucky_sum(13,
13, 2) → 015X
Can anyone show me an example where all test are success?
