**Problem**: Write a program in python to check whether a year is a leap year or not.

**Example:**

Input: 2020 Output: Leap Year Input: 2021 Output: Not a Leap Year

**A year is said to be a leap year if it is divisible by 4. It mostly occurs every 4 years but every 100 years we skip a leap year unless it is divisible by 400.**

Hence important point to note is that every year which is divisible by 4 is not necessarily a leap year, if the year is divisible by 100 then it should be divisible by 400 to be called a leap year.

Let’s write code in python to check leap year.

*Recommended: If else in Python*

```
year = int(input("Enter year: "))
if year%4==0 and year%100 != 0:
print("Leap Year")
elif year%400 == 0:
print("Leap Year")
else:
print("Not a Leap Year")
```

**Output**:

`Enter year: 2020
Leap Year`
