Comparison to Java / C++ Python run slower; but take much less time to develop. 3-5 times shorter than Java, 5-10 times shorter than C++ no type declaring, powerful polymorphic list and dictionary types Python as a "glue" language, while others as a low-level implementation language. Everything in python is an object, and it sits on the heap

Python is similar to Java Python is interpreted language while C++ is a compiled language Python class members are determined at run-time C++ has no has automatic memory management (garbage collection) Python have a full set of reflection capabilities; Serialization by pickle.saves()

WHY PYTHON? Trade-off between Productivity and Performance?
