    The complaints "Python is slow" or "Python is unsafe" seem misguided. The point of Python isn't to be fast or safe, it's to be flexible and hackable, and to interface well with everything else. It has become successful by serving as a frontend from which to call other libraries.

        Python is more of an interface than it is a development language. It's a UX. It seems perfectly sensible that there should be different languages for machines to execute and for people to work with. The requirements are different.

        I've never accepted that "unsafe" assertion. Due its higher-level constructs making programming simpler and clearer, the probability of bugs and security holes is actually LOWER for Python than for C/C++.

        In general I agree, but I'd really like to be able to use statically typed variables in Python, since it really helps to prevent many bugs.

        You're presupposing that "fast and safe" are mutually exclusive with "flexible and hackable", which is frankly a clear case of Stockholm Syndrome.

        +1. It's a lazy comment that you hear every few months. The correct question is always: "What is the objective you trying to achieve?". In most contexts, execution speed is not the most critical factor in achieving that objective (e.g. development speed is more important).

        What if you want to develop real-time applications? :) e.g. Real-time SLAM...

        Given the existence of numpy, Cython, and Numba, my judgement on anybody who complains about Python being slow would harsher than yours.

        This is only compounded by tensorflow. Python does have it's ugly sides, but speed isn't it.
