def summarize(list): n = 0 for i in list: n += i print 'the sum of {} is {}.'.format(str(list), n)
Return Syntax Error
# add_list([1, 2, 3]) should return 6
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.
list = [1, 2, 3]
def add_list(list):
n = 0
for i in list:
n += i
return n
def summarize(list):
n = 0
for i in list:
n += i
print 'the sum of {} is {}.'.format(str(list), n)

6,952 PointsIt looks like you're printing it instead of returning it. Is that what the issue is? It doesn't seem like a syntax error in itself, but it might cause it in the tester when it expects a string back from summarize and gets nothing.
By the way, you can cut down on the line count by having summarize call add_list. Why type the initialization and loop twice?
