Regex

The regular expression can be a compiled re object, or a string which will be compiled for you.

Use strip=True if you want to strip the value before validation, and as a form of conversion (often useful).

Examples:

>>> cap = Regex(r'^[A-Z]+$')
>>> cap.to_python('ABC')
'ABC'

Note that .from_python() calls (in general) do not validate the input:

>>> cap.from_python('abc')
'abc'
>>> cap(accept_python=False).from_python('abc')
Traceback (most recent call last):
  ...
Invalid: The input is not valid
>>> cap.to_python(1)
Traceback (most recent call last):
  ...
Invalid: The input must be a string (not a <type 'int'>: 1)
>>> Regex(r'^[A-Z]+$', strip=True).to_python('  ABC  ')
'ABC'
>>> Regex(r'this', regexOps=('I',)).to_python('THIS')
'THIS'
