Need help on finding AVERAGE in python -


this question has answer here:

what average value of numbers in field [quant] in range (198) , (272) inclusive

quant 95 189 176 200 177 340 205 203 284 88 109 83 360 67 250 56 111 439 354 143

this code tried. above [quant] field need find average. 

word_file = open('300000a.csv','r')  firstline = true  line in word_file:     if firstline:         firstline = false         continue     line = line.strip()     line = line.split (",")     field = int(line[0])  totalmetalcount +=1 if  field >198 or field <272:   metalcounts += 1 else:     metalcounts = 1   countt +=1 if field >198 or field <272:         count += 1

you can calculate average of list using sum , dividing length.

float(sum(my_list))/len(my_list)

if need grab few specific items , extract average based on can slice array.

print(float(sum(my_list[198:272]))/len(my_list[198:272]))

if have list contains strings, , not integers need convert them list of integers before can use sum.

my_list_of_integers = [int(i) in my_list[198:272] print(float(sum(my_list_of_integers))/len(my_list_of_integers]))

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
