Hello, this recursive function I made with python3 doesn't work well.
def func(teleports_string):
strings = [{n[0], n[1]} for n teleports_string.split(', ')]
start = {'1'}
def search(string, point, totalpoint):
For string in strings:
if point<=string and not string.difference(point)<=totalpoint:
iflen(totalpoint.union(point))>=7:
print(totalpoint)
return totalpoint
search(string, string.difference(point), totalpoint.union(string))
return search (string, start, set())
func("12, 23, 34, 45, 56, 67, 78, 81")
in the above code
return totalpoint
I would like to end the process with totalpoint as the return value in the line
I will start the rest of the process.
How can I end the process with return totalpoint?
Please let me know.
searchYou are recursively calling yourself at the end of the function.
search(string, string.difference(point), totalpoint.union(string))
There is no return here, so we are continuing to run the outer for string in strings: even after we come back from recursive.Moreover, since the function eventually ended without a return, nothing returned (although it returned exactly None).
