答题辅助python代码实现

本文实例为大家分享了答题辅助python具体代码，供大家参考，具体内容如下

from screenshot import pull_screenshot
import time, urllib.request

try:
 import Image
except ImportError:
 from PIL import Image, ImageDraw

import pytesseract

# 屏幕顶端到问题的距离/屏幕高度，随分辨率变化（默认1920*1080）
top_off_c = 0.15
# 问题高度
que_h = 300
# 答案高度
ans_h = 170

# 左右偏移量
l_r_off = 40

 resp = urllib.request.urlopen(q_url)

 print(resp.read().decode("utf-8"))
