Should I make python code less reliable to improve readability?

I'm trying to make my code flawless, but I noticed that it takes a lot of time to enter text, and it takes more time to read the code.

Instead:

class TextServer(object):
    def __init__(self, text_values):
        self.text_values = text_values
        # <more code>
    # <more methods>

I usually write this:

class TextServer(object):
    def __init__(self, text_values):
        for text_value in text_values:
            assert isinstance(text_value, basestring), u'All text_values should be str or unicode.'
            assert 2 <= len(text_value), u'All text_values should be at least two characters long.'
        self.__text_values = frozenset(text_values) # <They shouldn't change.>
        # <more code>
    @property
    def text_values(self):
        # <'text_values' shouldn't be replaced.>
        return self.__text_values
    # <more methods>

Is my python coding style too paranoid? Or is there a way to improve readability while maintaining impeccability?

  • Note 1: I added comments between <and >for clarification only.
  • Note 2: The main fool I'm trying to prevent in order to abuse my code is my future.
