I changed kenneth.sneaky to an integer and this happened...Why

is it because any other value other than False is True?

Not quite, but you are not too far off.

When you use a Non-Boolean (string, int, etc) in a place that expects a Boolean Python will automatically convert it to a Boolean value. It does so by checking if the value is on a list of values it considers to be a "Falsey" value. If that is the case it converts it to False, if the value is not on that list then it is treated as "Truthy" by default and converted to True.

Here is the list of values that Python considers "Falsey":

• None
• False
• Zero of any numeric type, for example, 0, 0L, 0.0, 0j.
• Any empty sequence, for example, '', (), [].
• Any empty mapping, for example, {}.
• Instances of user-defined classes, if the class defines a nonzero() or len() method, when that method returns the integer zero or bool value False.

Since 333 is not on the above list it is considered "Truthy" and is therefore treated the same as True.
