Yes, that is the achilles heel of Python.
I am always torn between Python and PHP for new projects because of this.
The Python Syntax plus its import system are huge advantages over PHP. On the other hand, you suffer a 6x slowdown if you go with Python. Decisions decisions. I so dearly wish I could have the good parts of both worlds.
And for data processing of all things ...
Php is also very slow, on top of being many other kinds of unpleasant and broken.
That doesn't make it fast at all. Just faster than if it wasn't jitted.
And that certainly does not eradicate the vast ocean of other problems php has, the first of which being that is was never, ever "though out" and instead grew like a cancerous mushroom.
I think that is pip.
