Python Curses中derwin（）对象中的.addstr（）出现奇怪错误

Question

我试图将一个curses中的窗口分割成几个子窗口（使用derwin()）。在

代码创建了两个子窗口，我可以添加一个字符串；第一个函数没有问题。第二个几乎完全相同，但是当我试图添加一个带有addstr()的字符串时，会出现一个错误

class Window(GUI):
'''
Window-object
'''

def __init__(self, y_max , x_max, y_pos , x_pos, Target, screen):
    self.Win_Count = 0
    self.y_pos = y_pos
    self.x_pos = x_pos
    self.y_max = y_max
    self.x_max = x_max
    self.parent = screen 
    self.Target = Target

    #Window-Objects
    self.Win = self.create_win_parent(y_pos)
    self.Name_Win = self.create_name_win(self.Win)
    self.IP_Win = self.create_ip_win(self.Win)

def create_win_parent(self, y_pos):
    y_size = 1
    x_size = self.x_max - self.x_pos
    new_win_obj = self.parent.derwin(y_size, x_size, self.y_pos, 0)
    self.Win_Count += 1
    return new_win_obj

def create_name_win(self, Win_Obj):
    x = Win_Obj.derwin(1,40, 0,0)
    x.box()
    x.addstr(0,5," CUSTOMER NAME ")
    return x

def create_ip_win(self, Win_Obj):
    x = Win_Obj.derwin(1,15, 0,41)
    x.box()
    x.addstr(0,5," IP-ADDRESS ")
    return x

我得到了一个模糊的错误：

^{pr2}$

Answer 1

def create_ip_win(self, Win_Obj):
    x = Win_Obj.derwin(1,15, 0,41)
    x.box()
    x.addstr(0,5," IP-ADDRESS ")
    return x

在这个函数中，Win_Obj.derwin(1,15, 0,41)表示x-pos应该在0和14之间。而在代码中addstr(0,5," IP-ADDRESS ")x从5开始，字符串" IP-ADDRESS "的长度大于（15-5）。所以你得到了错误。在
