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.

def fibo(params):
 i = 0
 j = 1
 sequence = 
 current_operation = 0
 for current_n in range(0, params+1):
 # We appends now, since f(0) = 0 = i_initial , f(1) = 1 =j_initial
 sequence.append(i)
 # prepare next opération
 current_operation = i + j
 i = j
 j = current_operation

 return sequence

print(fibo(10))

from flask import jsonify

@app.route("/fibonacci/<int:param_fi>/")
def get_fibo(param_fi):
 return jsonify(fibo(param_fi))
