Python, like all dynamically typed languages, has no readability once you start using multiple modules. Static types are important for declaring interfaces between components. I have pretty much written off Python, particularly now that Go exists. I've wasted too many hours tracing down data types in complicated Python programs, usually resorting to printing out the types at runtime to decode them. The problem with Python: it is great for simple programs, where the effort to writing the simple program is much less than the comparable program in C/C++/Java; but simple programs often grow into complicated programs, and then the effort of maintaining Python far exceeds the effort to maintain C/C++/Java. Go, on the other hand, is pretty nice for writing a simple program, and can then scale into a complicated program.
