I'm just learning python. Can you please tell me where could be the error?

import math

data = input()
length = len(data)
list = []
i = 0

while i < length:
    if data[i] != " " and data[i] != "\n":
        end_index = i
        for j in range(i + 1, length):
            if data[j] == " " or data[i] == "\n":
                break
            end_index += 1
        list.insert(0, int(data[i:end_index + 1]))
        i = end_index + 1
    else:
        i += 1

for e in list:
    value = round(math.sqrt(e), 4)
    print(f'{value:.4f}')

You only need to write about 3 lines of python code to solve this.

try:
  help(str.split)
  help(reversed)
  help(str.join)
