def newton(n):
#Define the variables.
t = 0.000001
esti = 1.0

dif = abs(n - esti ** 2)
if dif <= t:
break
#Return the result.
return esti
#Define the main function.

#Continue until user press enters.
while True:
try:
#Prompt the user for input.
n = int(input("Enter a number (Press Enter to stop):"))
#display the results.
print("newton = %0.15f" % newton(n))
