##8. Write an if statement that uses the turtle graphics library to determine

##whether the turtle’s heading is in the range of 40 degrees to 50 degrees

##including 40 and 50 in the range). If so, raise the turtle’s pen.

##Solution:

##angle = float(input('Enter the angle from 40 to 50: '))

##import turtle

##turtle.left(angle)

##turtle.forward(distance)

##if turtle.heading() >= 40 and turtle.heading() <= 50:

## turtle.penup()

## print('Turtle pen is up')

###8.1 A little extension of 8: Write an if statement that uses the turtle graphics

##library to determine whether the turtle’s nose (turtle coordinates) is closer

##to the point (100,100) than 5.

##If so, raise the turtle’s pen and print 'Good shot', if it is not so, don't

##raise anything just print 'Bad shot'.

##Solution possible:

## angle = float(input('Enter the angle between 40 and 50: '))

##distance = float(input('Enter the distance to go: '))

##import turtle

##turtle.left(angle)

##turtle.forward(distance)

##a = turtle.xcor()

##b = turtle.ycor()

##import math

##d = math.sqrt((a - 100)**2 + (b - 100)**2)

##if d < 5:

## turtle.penup()

## print('Good shot')

##else:

## print('Bad shot')

QUESTION: write this program without using math module and square root.

main.py

def square_root(num):

first = 0

last = num

x = 0

minimum_ranges = 0.0000000001;

while last - first > minimum_ranges:

x = (first + last) / 2.0;

powers = x * x

if abs(powers - num) <= minimum_ranges:

return x

elif powers < num:

first = x

else:

last = x

return x

number = int(input("Enter the number to root: "))

print(square_root(number))

Indentation:
