Code :

print("Insert lenght of proposed triangle: ")

x = float(input("x = "))

y = float(input("y = "))

z = float(input("z = "))

if x+y>z and x+z>y and y+z>x:

    print("The triangle of xyz exist")

else:

    print("The triangle does not exist")

3. How to check if a point belongs to Circle in python.

Code :

import math

x = float(input("Insert point x: "))

y = float(input("Insert point y: "))

r = float(input("Insert the radius: "))

hypotenuse = math.sqrt(pow(x,2) + pow(y,2))

if hypotenuse <= r:

    print("The point belongs to circle.")

else:

    print("The point does not belong to circle.")

4. How to create quadratic Equation in python.

Code :

from math import sqrt

x = float(input("Insert x = "))

y = float(input("Insert y = "))

z = float(input("Insert z = "))

a = y*y-4*x*z

if a>0:

    x1 = (-y + sqrt(a))/(2*x)

    x2 = (-y - sqrt(a))/(2*x)

    print("x1 = %.2f; x2 = %.2f" % (x1,x2))

elif a==0:

    x1 = -y/(2*x)

    print("x1 = %.2f" % x1)

else:

    print("No roots exist")

Output :

5.How to make ques of Random number in python.

Code :

from random import randint

guess_num = randint(1,100)

user_input = 0

trial_period = 1

while guess_num != user_input:

    print("The trial no %d: " % trial_period, end='')

    user_input = int(input())

    if user_input < guess_num:

        print("The input number is less")

    elif user_input > guess_num:

        print("The input number is much")

    else:

        print("Kudos! The right guess...")

    trial_period += 1

Output :
