Let’s say some words about the infamous Duck Typing approach to see how it fits in this paradigm: program to an interface. If it looks like a duck and quacks like a duck, it's a duck! Tweet We don’t bother with the nature of the object, we don’t have to care what the objec...
decompiling these. Among those that successfully decompile, we can then make sure the resulting programs are syntactically correct by running the Python interpreter for that bytecode version. Finally, in cases where the program has a test for itself, we can run the check on the decompiled code....

For those unfamiliar with importing, let's imagine we're writing a very large program. This program is several thousand lines of code. We could dump it all into the same file, but that wouldn't be too clean (especially when we have multiple developers working on it). Alternatively, we ...
