I've been a javascript dev for many years and I'm just now starting to learn Python. This seems like it should work, but for some reason I get the error:
local variable 'var_a' referenced before assignment
var_a = 0
var_b = 0
var_c = 0
def accumulate(tup):
var_a += tup[3]
var_b += tup[4]
var_c += tup[5]
return (tup[0], var_a, var_b, var_c)
insert = list(map(accumulate, output))
print(insert[-5:])
Maybe there's also a much better way of doing this. I also tried using the keyword nonlocal, but my compiler didn't even let me run that.
Clearly there's something very basic I don't understand.
