I disagree slightly. The problem with Python is that it may be quick and easy to cobble together something that does what you want, but it is a pain in the ass for someone else to install and use.

There is no shortcut where you can produce and distribute a binary so every damn user of your program will have to deal with Python versioning, installing dependencies etc.

So for the user, Python is not productive. It is time-consuming and bothersome.
