We had to calculate the players in the range of one standard deviations? My code is not excepted, however it works in other IDE

Question

import math
players = [180, 172, 178, 185, 190, 195, 192, 200, 210, 190]
mean = sum(players)/len(players)
var = sum((x-mean)**2 for x in players) / len(players)
std_deviation = math.sqrt(var)
print(std_deviation)
upper_limit = int(mean + std_deviation)
lower_limit = int(mean - std_deviation)
z_v1 = players[0] - mean / std_deviation
z_v2 = players[1] - mean / std_deviation
z_v3 = players[2] - mean / std_deviation
z_v4 = players[3] - mean / std_deviation
z_v5 = players[6] - mean / std_deviation
z_v6 = players[7] - mean / std_deviation
z_v7 = players[8] - mean / std_deviation
z_v8 = players[9] - mean / std_deviation
z_v9 = players[10] - mean / std_deviation
z_v_list = [z_v1, z_v2 , z_v3 , z_v4, z_v5, z_v6, z_v7, z_v8, z_v9]
for x in z_v_list:
if int(x) >= lower_limit and int(x) <= upper_limit:
print(x)
else:
print("no value found in range of one standard deviation")

Answer 1

Only print the number if player in range – not anything else.

And don't cast to integer, just leave it as float.
Why do you modify the given players' values? I don't understand that part... (And why not use a loop?)

Answer 2

On line 18, you try to access element of list - players with index 10, which does not exist:

z_v_list = players[10]...

So your program gives error : index out of range.

Answer 3

It's a code project task, right? Read the instructions carefully: We need to print the number of players in range – not the player in range.

I don't think you need z_v_list

Answer 4

What you're doing in the for loop makes no sense. The values in z_v_list are the ratios between the difference of player's heights from the mean and the standard deviation. If this ratio is between -1 and 1 the player's height is within a standard deviation of the mean.
If you want to use lower_limit and upper_limit you can check if the player's height lies between them.
At the end you have to print a single number, namely the number of players whose height is within one standard deviation of the mean.

Answer 5

import math
players = [180, 172, 178, 185, 190, 195, 192, 200, 210, 190]
mean = sum(players)/len(players)
var = sum((x-mean)**2 for x in players) / len(players)
std_deviation = math.sqrt(var)
print(std_deviation)
upper_limit = (mean + std_deviation)
lower_limit = (mean - std_deviation)
z_v1 = players[0] - mean / std_deviation
z_v2 = players[1] - mean / std_deviation
z_v3 = players[2] - mean / std_deviation
z_v4 = players[3] - mean / std_deviation
z_v5 = players[4] - mean / std_deviation
z_v6 = players[5] - mean / std_deviation
z_v7 = players[6] - mean / std_deviation
z_v8 = players[7] - mean / std_deviation
z_v9 = players[8] - mean / std_deviation
z_v9 = players[9] - mean / std_deviation
z_v10 = players[10] - mean / std_deviation
z_v_list = [z_v1, z_v2 , z_v3 , z_v4, z_v5, z_v6, z_v7, z_v8, z_v9, z_v10]
for x in z_v_list:
if (x) >= lower_limit and (x) <= upper_limit:
print(x)
else:
print("no value found in range of one standard deviation")

Answer 6

The above code gives me the two values that is in the range

Answer 7

But why here it doesn't work

Answer 8

Thanks a lot .
