Error even though I am getting good output

I am getting this error. Any idea on what to do to solve for my problem. The code produces good output however I am getting this error. Full disclosure this is a homework problem.

Traceback (most recent call last):
  File "nt-test-c364d945", line 3, in <module>
    assert(newton.newton(49) == 7.000000000000002)
AttributeError: module 'newton' has no attribute 'newton'

   """
File: newtons.py
Compute the square root of a number (uses function with loop).

1. The input is a number, or enter/return to halt the
   input process.

2. The outputs are the program's estimate of the square root
   using Newton's method of successive approximations, and
   Python's own estimate using math.sqrt.
"""
import math

tolerance = 0.000001
def newton(x):
   estimate = 1.0
   while True:
        estimate = ((estimate + x / estimate) / 2)
        difference = abs(x - estimate ** 2)
        if difference <= tolerance:
            break
   return estimate

def main():
   while True:
       x = input("Enter a positive number or enter/return to quit: ")
       if x == '':
           break    
       x = float(x)
       print("The program's estimate is", newton(x))
       print("Python's estimate is     ", math.sqrt(x))

if __name__ == "__main__":
    main()```

Referring to your traceback, you're using newton.newton(49) method in your script, but also you said that this newton funciton is inside newtons module, so looks like you need to use newtons.newton(49) (Don't forget to change import newton to import newtons)
