I don't really know what it is you are trying to achieve, but I can tell
you this, if you add a print statement you can see very clearly why you are
getting the error:
def survivor(names, step):
index = step - 1
next = names
while len(next)> 1:
print next, index
next.remove (next[index])
survivor(["Andrew", "Brenda", "Craig", "Deidre", "Edward",
"Felicity", "Greg", "Harriet"], 4)
['Andrew', 'Brenda', 'Craig', 'Deidre', 'Edward', 'Felicity', 'Greg',
'Harriet'] 3
['Andrew', 'Brenda', 'Craig', 'Edward', 'Felicity', 'Greg', 'Harriet'] 3
['Andrew', 'Brenda', 'Craig', 'Felicity', 'Greg', 'Harriet'] 3
['Andrew', 'Brenda', 'Craig', 'Greg', 'Harriet'] 3
['Andrew', 'Brenda', 'Craig', 'Harriet'] 3
['Andrew', 'Brenda', 'Craig'] 3
Traceback (most recent call last):
File "C:\Users\user\workspace\pricing\pricing\pricer\tests.py", line 40,
in <module>
"Felicity", "Greg", "Harriet"], 4)
File "C:\Users\user\workspace\pricing\pricing\pricer\tests.py", line 38,
in survivor
next.remove (next[index])
IndexError: list index out of range
As you can see in this line: ['Andrew', 'Brenda', 'Craig'] 3
It looks for index "3" and there isn't one, so it throws an error. The
indexes available are 0,1 and 2.
