A **Square is a planar shape** which have all of its sides being equal like a closed shape having sides as 4, 4, 4, 4 will be a **Square**. Mathematically perimeter of Square is defined as **four times of side of square**. Simple if side of square is **s** then perimeter of square will be **4 * s**.

Let’s Program this as **Python Code for Finding Perimeter of Square**.

```
# Calculating Perimeter of Square Using Python
s = float(input("Enter Side of Square => "))
# Perimeter of Square
perimeter_of_square = 4 * s
# Printing out parameter of Rectangle
print("Perimeter of Square is =>", perimeter_of_square)
```

**Output of Above Code**

```
Enter Side of Square => 5
Perimeter of Square is => 20.0
```
