Hello,
You can sort of look into the underlying code by using __code__, and it's
associated methods.
I was able to get the variable names with:
print(funct1.__code__.co_varnames).
I was sort of able to get to the value 10 with:
print(func1.__code__.co_consts).
This way seems pretty messy. Other people probably have more elegant ways
of doing this.
I hope this helps.
Best Regards,
Yuan
