### Suggestions:
# - test that sd_calc([1, 1, 1, 1]) returns 0.0
# - test that sd_calc([-1, 0, 1]) returns 1.0
# - test that sd_calc([]) returns 0.0

### Function:
import math
import sys
def sd_calc(data):
    n = len(data)
    if n <= 1:
        return 0.0
    mean, sd = avg_calc(data), 0.0
    for el in data:
        sd += (float(el) - mean)**2
    sd = math.sqrt(sd / float(n-1))
    return sd
def avg_calc(ls):
    n, mean = len(ls), 0.0
    if n <= 1:
        return ls[0]
    for el in ls:
        mean = mean + float(el)
    mean = mean / float(n)
    return mean

### Current tests:
import unittest
from target import sd_calc

class TestSdCalc(unittest.TestCase):
    def test_basic(self):
        assert sd_calc([4, 2, 5, 8, 6])== 2.23606797749979

### Improved tests:
