It has become successful largely because it has always had really good foreign function interface. If you have a scientific or mathematical library laying around in C, then you could wire it up to Python, and then suddenly you have all the flexibility of a (fairly clean) scripting language to orchestrate your high speed C. Good examples of this are numpy and tensorflow.
