Python, Basketball players

Can someone tell me what I have done wrong? (my code is below). The given code includes a list of heights for various basketball players. You need to calculate and output how many players are in the range of one standard deviation from the mean. players = [180, 172, 178, 185, 190, 195, 192, 200, 210, 190] x=0 for i in range(len(players )): x+=players[i] mean=x/len(players) y=0 for i in range(len(players)): y+=(players[i]-mean)**2 var=(y/len(players)) std=var**(1/2) for i in range(len(players )): if players[i]>(mean-std) and players[i]<(mean+std): print(players[i])

You should declare numPlayers = 0 And in the last loop and the if add them numPlayers +=1 Instead print the each player And after the loop print the number numPlayers.

You need to print the scores that are within one standard deviation from the mean, not the std itself. For example if the mean is 200 and the std is 10. Then 190, 191, 192, 193 ... 201, 202, 203, 204 up to 210 is within one standar deviation. Hint: Use for loop to iterate each scores and have conditions that checks if the score is within one std.
