Answer:
This example shows the basic arithmetic operations i.e.
- Addition
- Subtraction
- Multiplication
- Division
# Store input numbers:
num1 = input('Enter first number: ')
num2 = input('Enter second number: ')
# Add two numbers
sum = float(num1) + float(num2)
# Subtract two numbers
min = float(num1) - float(num2)
# Multiply two numbers
mul = float(num1) * float(num2)
#Divide two numbers
div = float(num1) / float(num2)
# Display the sum
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))
# Display the subtraction
print('The subtraction of {0} and {1} is {2}'.format(num1, num2, min))
# Display the multiplication
print('The multiplication of {0} and {1} is {2}'.format(num1, num2, mul))
# Display the division
print('The division of {0} and {1} is {2}'.format(num1, num2, div))
Answer:
NUMBER GUESSING GAME-
import random
secret = random.randint(1, 99)
guess = 0
tries = 0
print "AHOY! i'm the Dread Pirate Roberts' and I have a secret!"
print "It is a number from 1 to 99. I'll give you 6 tries. "
while guess != secret and tries < 6:
guess = input("What's yer guess? ")
if guess < secret:
print "Too low' ye scurvy dog!"
elif guess > secret:
print "Too high,landlubber!"
tries = tries + 1
if guess == secret:
print "Avast! Ye got it! Found my secret, ye did"
else:
print "No more guesses! Better luk next time, matey"
print " The secret number was", secret
