I personally found Go far more unproductive than Python - doing if err!=nil a zillion times and writing the nth for loop..it made me cry worse than cutting fresh onions.
Python is not Perfect (bad general-purpose performance), but IMHO honestly a more productive language than Go.
And Python has type hinting nowadays which is sweet when you want it. Type hinting is good for self-documenting stable code.
I never minded the boilerplate. Pushing buttons on a keyboard never slowed me down very much, especially compared to finding and fixing bugs or even writing gratuitous test cases to guard against type errors. If I could only press a few buttons per minute or if I could write many test cases per minute I might feel differently.
