Does anyone know how to solve basketball players 5 code project in python for data science course?

Question

So we are supposed to calculate and output how many players are in the range of one standard deviation from the mean.
Below is my code which seems right to me, but when its run the test case says its wrong. Does anyone know how to solve it...
players = [180, 172, 178, 185, 190, 195, 192, 200, 210, 190]
final_inrange = 0

import numpy as np

a = np.array([180, 172, 178, 185, 190, 195, 192, 200, 210, 190])

mean = np.sum(a)/a.size
print(mean)

variance = np.sum((a-mean)**2)/a.size

std = np.sqrt([variance])
#print(std)
#print(std.format(".2f"))

in_range1 = (mean - std)
in_range2 = (mean + std)
#print(in_range2)

for count in range(10):
if players[count]>in_range1 and players[count]<in_range2:
final_inrange = final_inrange+1
inrange = players[count]
#print(inrange)
print(final_inrange)

Answer 1

players = [180, 172, 178, 185, 190, 195, 192, 200, 210, 190]

mean = sum(players)/len(players)

stdvar = (sum((v-mean)**2 for v in players)/len(players))**0.5

low, high = mean-stdvar,mean+stdvar

count = len([v for v in players if low < v < high])

print(count)
