What’s the easiest possible way to cause stacktraces to also dump local variable information? I feel like this is a feature that should be built into the language…
On my local machine it’s even better because I can run the code, let it break and then jump straight into the debugger where I can move up and down through the stack. I can sit in the context at any point and play with the data. I can call any Python function I want to see how the code behaves.

With Python, you can run your program under pdb, which will automatically enter break on exceptions, and you can easily print locals.
That is built into Python!
import sys
def div(x, y):
return x / y
try:
print(div(1, 0))
except ZeroDivisionError as e:
print("Div by zero!")
print("Locals:")
_, _, tb = sys.exc_info()
print(tb.tb_next.tb_frame.f_locals)
Div by zero!
Locals:
{'x': 1, 'y': 0}
