This Python code checks if a given number is a sunny number. A number đť‘› is considered a sunny number if đť‘›+1 is a perfect square. The `perfectSquare`

function determines if a number is a perfect square by checking if its square root is an integer. The `isSunnyNumber`

function uses this to verify if đť‘›+1 is a perfect square and prints the result. The user is prompted to enter a number, and the program then outputs whether the number is a sunny number or not.

```
import math
# Function to check if a number is a perfect square
def perfectSquare(n):
# Calculate the square root of the number
square_root = math.sqrt(n)
# Check if the square root is an integer (perfect square)
return((square_root - math.floor(square_root)) == 0)
# Function to check if a number is a sunny number
def isSunnyNumber(n):
# Check if n+1 is a perfect square
if (perfectSquare(n + 1)):
# If true, print that the number is a sunny number
print(str(n) + " is a sunny number!")
else:
# If false, print that the number is not a sunny number
print(str(n) + " is not a sunny number!")
# Prompt the user to enter a number
print("Enter a number to check for sunny number:")
# Read the input and convert it to an integer
sunnyNumber = int(input())
# Check if the entered number is a sunny number
isSunnyNumber(sunnyNumber)
```

```
Enter a number to check for sunny number:
48
48 is a sunny number!
```

`import math`

**Importing Math Module**:`import math`

imports the Python math module, which provides mathematical functions, including`math.sqrt`

for calculating the square root of a number and`math.floor`

for getting the largest integer less than or equal to a given number.

```
def perfectSquare(n):
square_root = math.sqrt(n)
return((square_root - math.floor(square_root)) == 0)
```

**Function Definition**:`def perfectSquare(n):`

defines a function named`perfectSquare`

that takes an integer`n`

as its argument.**Calculate Square Root**:`square_root = math.sqrt(n)`

computes the square root of`n`

and assigns it to the variable`square_root`

.**Check if Perfect Square**:`math.floor(square_root)`

computes the largest integer less than or equal to`square_root`

.`square_root - math.floor(square_root)`

calculates the difference between`square_root`

and its floored value. If`n`

is a perfect square, this difference will be 0 because`square_root`

will be an integer.`return((square_root - math.floor(square_root)) == 0)`

returns`True`

if the difference is 0 (indicating`n`

is a perfect square) and`False`

otherwise.

```
def isSunnyNumber(n):
if (perfectSquare(n + 1)):
print(str(n) + " is a sunny number!")
else:
print(str(n) + " is not a sunny number!")
```

**Function Definition**:`def isSunnyNumber(n):`

defines a function named`isSunnyNumber`

that takes an integer`n`

as its argument.**Check if**:`n+1`

is a Perfect Square`if (perfectSquare(n + 1)):`

calls the`perfectSquare`

function with`n + 1`

as the argument. If the result is`True`

(indicating`n + 1`

is a perfect square), it executes the following block.`print(str(n) + " is a sunny number!")`

prints that`n`

is a sunny number.`else:`

executes the following block if`perfectSquare(n + 1)`

returns`False`

.`print(str(n) + " is not a sunny number!")`

prints that`n`

is not a sunny number.

```
print("Enter a number to check for sunny number:")
sunnyNumber = int(input())
```

**Prompt for Input**:`print("Enter a number to check for sunny number:")`

prints a message asking the user to enter a number.**Read Input**:`sunnyNumber = int(input())`

reads the user input, converts it to an integer, and assigns it to the variable`sunnyNumber`

.

`isSunnyNumber(sunnyNumber)`

**Check Sunny Number**:`isSunnyNumber(sunnyNumber)`

calls the`isSunnyNumber`

function with`sunnyNumber`

as the argument to check if it is a sunny number and print the result.
