"powerful in Python. Thanks to the way imports and modules are handled in Python, it is " | |
"relatively easy to structure a Python project. Easy, here, means that you do not have many " | |
"constraints and that the module importing model is easy to grasp. Therefore, you are left " | |

"today. Because Hadoop is taking on all sorts of capabilities that just two years ago were " | |
