You can use a math formula to find the percentage difference between two numbers in Python. Percentage Difference = |(Number1 – Number2) / ((Number1 + Number2) / 2)| * 100.

Formula to calculate percentage:

`(Percentage2 – Percentage1) * 100 / (Percentage1) `

## Example percentage difference between two numbers in Python

A simple example code finds the percentage of the difference between two numbers.

```
a = 10
b = 15
result = int(((b - a) * 100) / a)
print(result, "%")
```

**Output**: 50 %

**User input number**

```
first = int(input("Enter first number: "))
second = int(input("Enter second number:"))
res = ((first - second) / first) * 100
print("Difference in percentage is : {}%".format(res))
```

**Output**:

```
def percentage_difference(number1, number2):
if number1 == number2:
return 0 # The numbers are the same, so the percentage difference is 0.
# Calculate the percentage difference using the formula
percentage_diff = abs((number1 - number2) / ((number1 + number2) / 2)) * 100
return percentage_diff
# Example usage
number1 = 50
number2 = 60
percentage_diff = percentage_difference(number1, number2)
print(f"The percentage difference between {number1} and {number2} is {percentage_diff:.2f}%")
```

In this code, the `percentage_difference`

function takes two numbers as input and calculates the percentage difference using the formula. It first checks if the two numbers are equal, in which case the percentage difference is 0. Otherwise, it calculates the percentage difference and returns the result.

You can replace `number1`

and `number2`

with your own values to calculate the percentage difference between any two numbers.
