Python“使用错误的参数类型调用"错误

问题描述

我明白为什么我会收到这个错误，它正在寻找我的对象作为参数，并接收一个字符串值.但我不知道解决方案是什么?

I understand why I am getting this error, it's looking for my object as an argument, and receiving a string value. But I'm confused as to what the solution would be?

以下代码片段只是尝试运行此命令；

The following code snippet is simply trying to run this command;

self.buttonGroup.addButton(self.ui.m001)

x 次:

num = 0
range_ = 10
prefix = "m"

for i in range (range_):
    if num <(range_-1):
        numString = "00"+str(num)
        if (num >9):
            numString = "0"+str(num)

        button = "self.ui."+prefix+numString

        self.buttonGroup.addButton(button)
        num +=1

print self.buttonGroup

推荐答案

问题是button是字符串，一个可能的解决方案是使用getattr.

The problem is that button is a string, a possible solution is to use getattr.

变化:

button = "self.ui."+prefix+numString

到

button = getattr(self.ui, prefix+numString)
