You seem to have just discovered Python's dynamicity. You may not yet be
in a position to understand the *benefits* of this dynamicity in large
programs which go along with its costs. Sometimes Python's dynamic
features will allow thousands of lines of Java or C++ code to just melt
away into a few lines of Python. That increases the overall reliability
of the system. Python also makes testing much easier. Therefore you can
do more testing in less time and thus improve the stability of your
program.
