where is the error ? python for data science project 2

Question

import numpy as np

data = np.array([150000, 125000, 320000, 540000, 200000, 120000, 160000, 230000, 280000, 290000, 300000, 500000, 420000, 100000, 150000, 280000])
SD=np.std(data)
MEAN=np.mean(data)
c=SD+MEAN
d=SD-MEAN
low, high = d,c
count = len([v for v in data if low < v < high])
print(count*100/len(data))

Answer 1

I think I use d = MEAN - SD

Answer 2

Paul is right.

A much more minor improvement would be to eliminate your c and d variables and just directly store into high and low like the following:

SD=np.std(data)
MEAN=np.mean(data)
high=MEAN+SD
low=MEAN-SD
count = len([v for v in data if low < v < high])
print(count*100/len(data))

The c and d variables make the code slightly less readable.

thanks man!!
