The Python stack is a huge wart. First performance is shit. Second type checking is shit.
The only benefit is familiarity and data science. That’s literally it. No one in this thread has stated any benefit Python brings to the table on top of other popular web application languages.
having built two enterprise data platforms in python, I can't disagree more. for a startup, development velocity matters more than code performance especially for a CRUD app even at medium scale. Frameworks like Django simply enable you to do so much and so quickly. and you can reach world scale, that's what Instagram did!
