num = int(input("Enter any number: ")) flag = num%2

if flag == 0:

 

print(num, "is an even number") elif flag == 1:

print(num, "is an odd number") else:

print("Error, Invalid input")

 

 

 

4. Aim: - write a Program for calculate the simple interest and compound interest in python Program:-

print("Program for calculate the simple interest and compound interest in python")

#Input

 

P = input("\n Enter the principal amount: ") T = input("\n Enter the time: ")

R = input("\n Enter the rate: ") #Process

Si = (int(P) * float(T) * float(R) ) /100

 

Ci = int(P) * (((1 + float(R)/100) ** int(T)) - 1) #Output

print("\n Simple Interest = ",Si) print("\n Compound Interest = ",Ci)

Output:-

Program for calculate the simple interest and compound interest in python Enter the principal amount: 1000

Enter the time: 6 Enter the rate: 9

Simple Interest = 540.0

Compound Interest = 677.1001108410006

 

 

5. Aim: - write a Python program to find the largest number among the three input numbers take three numbers from user

Program:-

print("Python program to find the largest number among the three input numbers take three numbers from user")

num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) num3 = float(input("Enter third number: "))

if (num1 > num2) and (num1 > num3):

 

largest = num1

 

elif (num2 > num1) and (num2 > num3):

 

largest = num2 else:

largest = num3

 

print("The largest number is",largest)

 

Output:-

Python program to find the largest number among the three input numbers take three numbers from user

Enter first number: 45 Enter second number: 100 Enter third number: 12

The largest number is 100.0

 

6. Aim: - write a Python Program to Convert Binary to Decimal and Decimal to Binary

Program:-

print("Python Program to Convert Binary to Decimal and Decimal to Binary")

b_num = list(input("Input a binary number: ")) value = 0

for i in range(len(b_num)): digit = b_num.pop() if digit == '1':

value = value + pow(2, i) print("The decimal value of the number is", value) def convertToBinary(n):

if n > 1:

 

convertToBinary(n//2) print(n % 2,end = '')

# decimal number

 

dec = int(input("Input a decimal number: "))

convertToBinary(dec) print()

Output:-
