Here's your problem - x is a class, *not* an instance of a class (i.e.

Python has some VERY nasty gotchas concerning parenthesis (or lack

In the first line here, you assign x = MyClass. That means x becomes an

Check out the .translate method and the string.maketrans documentation.
You can use it to delete a list of characters all in one line:

A quick glance tells you that the latter approach has less number of

Check out 'os.open'
It returns a file descriptor, and if you need a file object you can use
'os.fdopen' on the file descriptor

To access the doc string of a property,
I have to use the class not an instance.
Why?

Because getting the attribute from the instance gets the calculated value (the
value returned from the getter function), not the actual property object.
