Question

我正在尝试用Pyautogui为MMO创建一个叫做“Graal Online Classic”的机器人。它会读取发送消息的玩家的“PM”，然后回复相应的响应。它还会截取玩家名称的截图，并将其转换为带有tesseract的字符串，并将其存储在字典中（还存储特定玩家在机器人的响应层次结构中的位置），并使用它来确定玩家是否有消息他们之前。

def player_id(name_coords, option): # Indentifies person who messaged and depending on if this person has messaged before changes response 
    players = {} # Used to store players names and where in the response is 
    keys = players.keys() 

    image = pyautogui.screenshot('name_test.png', region = name_coords) # Names are screenshots 
    name_image = str(pytesseract.image_to_string(Image.open('name_test.png'))) 
    print(name_image) 
    for name_image in keys: 
     print("User is previous user.") 
     if players[name_image] == None: 
      players[name_image] = option 
     else: 
      players[name_image] = players[name_image] + option 
     return players[name_image] 
    else: 
     print("User was not previously found, adding to dictionary.") 
     players[name_image] = None 
     print(players.keys()) 
     print(players) 

问题源于上述功能。当它发现之前有消息的人时，应该去if语句，但无论如何，else语句都会执行。我在播放器中打印值，当播放器第二次发送消息时，它的值相同，但是在键中的name_image：仍然返回false。

运行程序的日志你并不需要一个for循环这里下面是完整的代码。这是使用字典的重点 - 避免昂贵的O（N）查找。字典查找速度很快。与

name = players.get(name_image) 
if name:  
    # your variable naming is totally unclear. I **think** this is what you want 
    players[name] = option 
    return players[name] 
else: 
    print("User was not previously found, adding to dictionary.") 
    players[name_image] = None 
    print(players.keys()) 
    print(players) 

注意，在你原来的cdoe，要定义name_image如下替换您的for循环：

name_image = str(pytesseract.image_to_string(Image.open('name_test.png'))) 

但该变量得到的比写在for循环。
