## Program Code – Applying Domains in Mathematical Functions to Programming

```
``````
def validate_domain(func):
'''
Decorator that checks if the input value is within the function's domain.
The domain should be specified in the function's docstring in the format:
'Domain: start-end', where start and end are the domain limits.
'''
def wrapper(x):
# Extracting domain from the docstring
domain_str = func.__doc__.split('Domain: ')[1]
start, end = map(int, domain_str.split('-'))
if start <= x <= end:
return func(x)
else:
raise ValueError(f'Input {x} is outside the domain of [{start}, {end}].')
return wrapper
@validate_domain
def my_func(x):
'''
This is a sample function to demonstrate applying domain in programming.
The function will return x^2.
Domain: 1-100
'''
return x ** 2
# Examples of calling the function
results = []
for i in range(-5, 105, 20):
try:
result = my_func(i)
results.append(f'my_func({i}) = {result}')
except ValueError as e:
results.append(f'Error for my_func({i}): {str(e)}')
```

### ### Code Output:

```
Error for my_func(-5): Input -5 is outside the domain of [1, 100].
my_func(15) = 225
my_func(35) = 1225
my_func(55) = 3025
my_func(75) = 5625
my_func(95) = 9025
Error for my_func(115): Input 115 is outside the domain of [1, 100].
```

### ### Code Explanation:

This program illustrates how to apply mathematical domains to programming. The concept of a domain, originating from mathematics, designates the set of input values for which a function is defined. The goal here is to ensure that a certain function in our code processes inputs only within its defined domain, much like how mathematical functions work.

- The
`validate_domain`

function acts as a decorator. It reads the domain specified in the function’s docstring, parses it, and checks if the input falls within this domain before calling the actual function. If the input is outside of the prescribed domain, it raises a ValueError, indicating that the input is not valid. - The decorated function,
`my_func`

, represents a simple mathematical operation: squaring its input. In its docstring, we define its domain as being from 1 to 100 inclusive. This is the set of acceptable input values. - The decorator extracts this domain from the docstring using basic string operations. It splits the docstring to find the domain, then splits the domain string itself into start and end values. These values are then compared against the function’s input.
- In the example usage, a loop attempts to call
`my_func`

with a range of values, some of which fall outside the defined domain. Whenever an input is out of bounds, our decorator intervenes, preventing the function from executing with that input and instead raising a custom error message.

By blending the precise discipline of mathematics with the versatility of programming through decorators, we’ve established a robust way to enforce input validation based on mathematical concepts, ensuring that our functions operate within their intended scopes. This method helps avoid potential errors or unexpected results from improper use, making our code not only more reliable but also more mathematically sound.
