Week 2 assignment error 2

[dzhao05]

I think my code is correct, but got error. Anyone has encountered the same? how did you resolved it? Thanks.

{moderator edit - solution code removed}

print("basic_sigmoid(1) = " + str(basic_sigmoid(1)))

basic_sigmoid_test(basic_sigmoid)

basic_sigmoid(1) = 2.718281828459045

No, your code is clearly not right. The output of sigmoid should be a number between 0 and 1, right? But your answer for sigmoid(1) = 2.71828...

We can see from your code that you have implemented

sigmoid(x) = e^x

But if you look at the formula for sigmoid, it’s a bit more complicated than that. When they said to “use math.exp” they did not mean that was the complete answer.

math.exp(x) is just the python equivalent of e^x. You need that as part of the formula, but that is not the whole story.
