How to answer Sololearn Code Coach challenge?

Question

I just tried the code coach for the first time, and picked up average word length or so

def average_length(str):
words = str.split(" ")
total_lengths, total_words = 0, 0
for word in words:
if(word.isalnum()):
total_lengths += len(word)
total_words += 1
return total_lengths // total_words + (total_lengths % total_words > 0)

Yet it says my code produces no output?? What's the format for the challenges?

Answer 1

Hi! When the program needs inputs, you use input(). When the program needs an output, you use print(). If the result is processed inside a function, you have to run the function:

def myFunction(arg):
….
return res

s = input()
result = myFunction(s)
print(result)

It's not up to Sololearn to call your function, it is up to you to write a code which calls the function.

That is how coding works.

It's up to Sololearn to pass me the arg. All things being equal the standard input is a prompt box displayed when i click run. I never knew it would be changed in certain scenario such as this. I think Per Bratthammar 's answer was just on point

and the line that's how coding works lol, rather how Sololearn challenge works.

write a function that does this and this is a valid question, only if that isn't coding

Answer 4

I think sololearn should call my function with the input
