如何將setStyleSheet顏色作爲列表中的項目傳遞？

Question

我正在使用pyqt 4.11，並試圖使用循環創建一組標籤，並且想要更改每個標籤的顏色。但是，顏色仍然是默認的黑色。

red = (255,0,0) 
orange = (255,128,0) 
yellow = (255,255,0) 
green = (0,255,0) 
loop = 0 
NAME = ["apple","banana","strawberry","orange"] 
NAME_COLOR = [green,yellow,red,orange] 

while loop < len(NAME): 
    lbl = QtGui.QLabel(self) 
    lbl.setText(NAME[loop]) 
    lbl.move(loop*50,120) 
    lbl.setStyleSheet('QLabel { color: NAME_COLOR[loop]}') 
    lbl.show() 
    loop = loop + 1

要設置標籤的顏色，你需要使用setStyleSheet如下：

lbl.setStyleSheet('color: rgb{}'.format("(255,128,0)")) 

下面是使用PyQt4的你的程序的工作示例：

from PyQt4 import QtGui 

red = (255, 0, 0) 
orange = (255, 128, 0) 
yellow = (255, 255, 0) 
green = (0, 255, 0) 

class Window(QtGui.QWidget): 

    def __init__(self, parent=None): 
     super(Window, self).__init__(parent) 

     layout = QtGui.QVBoxLayout() 

     name = ["apple", "banana", "strawberry", "orange"] 

     name_color = [green, yellow, red, orange] 
     _dict = dict(zip(name, name_color)) 
     # _dict = {'apple': (0, 255, 0), 'banana': (255, 255, 0), 
     #   'orange': (255, 128, 0), 'strawberry': (255, 0, 0)} 

     for name, color in _dict.items(): 
      label = QtGui.QLabel(self) 
      label.setText(name) 
      label.setStyleSheet('color: rgb{}'.format(str(color))) 
      layout.addWidget(label) 

     self.setLayout(layout) 


if __name__ == '__main__': 
    app = QtGui.QApplication([]) 
    w = Window() 
    w.show() 
    app.exec_() 

結果：
