It is hard to believe that Python is objectively that much more productive than other languages. I know Python moderately well (with much more real world experience in C#). I like Python very much but I don't think it is significantly more productive than C#.
This. C#, Java or even newcomers such as Kotlin/Go are even in the same ballpark due to the REPL/Jupyter alone. Let alone when you consider the ecosystem
If you are in a lab (natural science lab) or anywhere close to data, I bet you it is much more productive, even more so when you have to factor in that the code might be exposed to non-technical individuals.
