Basic Python Programs

Find Factorial using while Loop

 print("Enter the Number: ")

num = int(input())

fact = 1
i = 1
while i<=num:
    fact = fact*i
    i = i+1

print("\n Factorial =", fact)

Check Leap Year in python 

print("Enter the Year: ")
y = int(input())

if y%4==0 and y%100!=0:
    print("\nIt is a Leap Year")
elif y%400==0:
    print("\n It is a Leap Year")
else:
    print("\n It is not a Leap Year")

Check Reverse Equals Original in Python
print("Enter the Number: ")
num = int(input())

rev = 0
orig = num
while num>0:
    rem = num%10
    rev = rem + (rev*10)
    num = int(num/10)

if orig==rev:
    print("\n The Number is Equal to Its Reverse")
else:
    print("\n The Number is not Equal to Its Reverse")

Check Palindrome Number in Python

print("Enter the Number: ")
num = int(input())
rev = 0
temp = num
while temp>0:
    rem = temp%10
    rev = rem + (rev*10)
    temp = int(temp/10)
if rev==num:
    print("\n It is a Palindrome Number")
else:
    print("\n It is not a Palindrome Number")
