NO. OBJECTIVE & SOLUTION
1. Write a program in python to check a number whether it is prime or not.
num=int(input("Enter the number: "))
for i in range(2,num):
if num%i==0:
SOURCE print(num, "is not prime number")
CODE: break;
else:
print(num,"is prime number")


OUTPUT:

2. Write a program to check a number whether it is palindrome or not.
num=int(input("Enter a number : "))
SOURCE
CODE: n=num
res=0

, while num>0:
rem=num%10
res=rem+res*10
num=num//10
if res==n:
print("Number is Palindrome")
else:
print("Number is not Palindrome")


OUTPUT:

3. Write a program to calculate compound interest.
p=float(input("Enter the principal amount : "))
r=float(input("Enter the rate of interest : "))
t=float(input("Enter the time in years : "))
SOURCE
CODE: x=(1+r/100)**t

CI= p*x-p
print("Compound interest is : ", round(CI,2))

,OUTPUT:



4. Write a program to display ASCII code of a character and vice versa.
var=True
while var:
choice=int(input("Press-1 to find the ordinal value of a character \nPress-2 to
find a character of a value\n"))
if choice==1:
ch=input("Enter a character : ")
print(ord(ch))
elif choice==2:
SOURCE val=int(input("Enter an integer value: "))
CODE: print(chr(val))
else:
print("You entered wrong choice")

print("Do you want to continue? Y/N")
option=input()
if option=='y' or option=='Y':
var=True
else:

, var=False
Press-1 to find the ordinal value of a character
Press-2 to find a character of a value
1
Enter a character : a
97
Do you want to continue? Y/N
OUTPUT: Y
Press-1 to find the ordinal value of a character
Press-2 to find a character of a value
2
Enter an integer value: 65
A
Do you want to continue? Y/N
Write a program to input a character and to print whether a given character is an
5.
alphabet, digit or any other character.
ch=input("Enter a character: ")
if ch.isalpha():
print(ch, "is an alphabet")
SOURCE
CODE: elif ch.isdigit():
print(ch, "is a digit")
elif ch.isalnum():
print(ch, "is alphabet and numeric")
