Add Validation module

[Descent098]

The purpose of this module is to provide easy ways to validate strings are in the correct format for use.

TODO

• Create a validation class that can take in a regex string, and has 2 methods: __repr__(), validate()
• Add in the instances found in the Validation instances section

Validation class

import re
from dataclasses import dataclass

@dataclass
class Validator:
    validation_string:str

    def validate(self, value:str, as_bool:bool=False) -> :
        compiled_expression = re.compile(self.validation_string)
        if not as_bool:
            return compiled_expression.match(value) # Return full match groups
        else:
            return bool(compiled_expression.match(value))

    def __repr__(self) ->str:
        return self.validation_string
