I am using a flask app and url endpoint to allow the input of a number. I then want to display the fibonnaci sequence up until it is equal to or less than the inputted number.

This is what I currently have:

@app.route("/fibonacci/<int:param_fi>/")

def getFib(param_fi):

if param_fi < 2:

    return ('0,1,1')

else:

    L = getFib(param_fi-1)

    if L[-1] < param_fi:

        L.append(L[-1] + L[-2])

    return L

I am having trouble pinpointing exactly where the error is from. I have tried making a list and converting it to strings but can't ever get it to work. When I try this it returns the following error:
"The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a list."

I am looking for the following output:

/fibonacci/250(this is the user input)/

0,1,1,2,3,5,8,13,21,34,55,89,144,233

Or /fibonacci/90(this is the user input)/

0,1,1,2,3,5,8,13,21,34,55,89

Any help is appreciated.

@app.route("/fibonacci/<int:param_fi>/")

def getFib(param_fi):

    i = 0

    j = 1

    sequence = 

    current_operation = 0

    index = 0

    while True:

        sequence.append(i)

        current_operation = i + j

        i = j

        j = current_operation

        if i > param_fi:

            return json.dumps(sequence)

        else:

            index += 1

    return json.dumps(sequence)

I did not understand the error, can you output the result you want to have ? Do you need recursive like you did or no ?

But I guess you are missing something? You only return 0 or 1, or sum of both, so yes, you will never have the full sequence of the fibonacci.

You need to keep in memory the sequence, or return a list and adding elements each time, at least.
