Question

This is my code and I don't know why I'm getting error when I run this program on terminal.this is my python code python 3.5, I'm new to curses module and unable to handle this error ,thanks in advance

import urllib.request as ur
import time
import curses

def ini(i):

  url       = 'http://www.top4themes.com/data/out/134/6545537-superman-logo-wallpapers.jpg'
  req       = ur.urlopen(url)
  count     = 0
  block_size= 1024
  avg       = 0
  smin      = []
  value     = False
  t         = []

  while True:
    start   = time.time()
    buff    = req.read(block_size)
    stop    = time.time()
    avg    += len(buff)

    if not buff:
        break;

    if (stop-start) < 0.2 : 
        block_size += 2048

    elif (stop-start) > 0.2:
        block_size -= 1024

    count += 1
    stdscr(1,0,"{}".format(block_size))
    stdscr.refresh()
    t.append(int(block_size))

    if(block_size ==0):
        block_size=max(t)

 if __name__=="__main__": 
    stdscr = curses.initscr()
    curses.noecho()
    curses.cbreak()
    try:
        for i in range(10):
            ini(i)
            time.sleep(0.5)
    finally:
        curses.echo()
        curses.nocbreak()
        curses.endwin()

Answer 1

The error refers to the line stdscr(1,0,"{}".format(block_size)). Presumably you were going for something like stdscr.addstr(1,0,"{}".format(block_size)).
