function - Python issue gave up around 4am -

-

this question has answer here:

program requests 4 number (integer or floating-point) user. program should compute average first 3 numbers , compare average fourth. if equal, program should print 'equal' on screen.

import math x1 = input('enter first number: ') x2 = input('enter second number: ') x3 = input('enter third number: ') x4 = input('enter fourth number: ')  if ( x4 == (x1 + x2 + x3) / 3):     print('equal')

error message:

if ( x4 == (x1 + x2 + x3) / 3): typeerror: unsupported operand type(s) /: 'str' , 'int'"

second error message after trying convert int:

x1 = int(input('enter first number: ')) valueerror: invalid literal int() base 10:

you using mathematical operands on strings. here fix:

import math x1 = int(input('enter first number: ')) x2 = int(input('enter second number: ')) x3 = int(input('enter third number: ')) x4 = int(input('enter fourth number: '))  if ( x4 == (x1 + x2 + x3) / 3):     print('equal')

you have cast strings int.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
