Unsupported - Tuple and Int

Question

I've done a bit of research on this error but I still haven't been able to fix it. I've tried different syntax and codes. The error seems to be on lines mean_value= and std_value=.

# Moving Mean
for i in enumerate(inputs_filtered):
    mean_value = sum(inputs_filtered[i-smoothing:i])/smoothing

# Standard Deviation
for i in enumerate(inputs_filtered):
    std_value = math.sqrt(sum((inputs_filtered[i-smoothing:i])-mean_value)/smoothing)

Answer 1

Your problem is that using enumerate on a list is returning a tuple and not just i as you expected, it returns the index, and the value of that index.

so in your case, i is a tuple, and you're trying to subtract smoothing off of a tuple

e.g:

for index, val in enumerate([10,20,30,40,50]):
    print(index, val)
0 10
1 20
2 30
3 40
4 50

If you need to iterate and fetch the value for every index, use:

for value in inputs_filtered:
    # do something...
