按下另一个按钮时如何更改按钮的颜色（PyQT5，QT）

Question

Hello for my application, I am trying to change the color of one button when different button is pressed.

I am doing this by creating a global boolean variable called changeSymbol, and one of the buttons will change when the changeSymbol returns true.

Here is my code: [EDIT Due to difficulties in copy and pasting (also I am new to stack overflow) I will post screenshots instead]

I don't know if I understand problem because I can't see full code.

Maybe you should do all in one function

def Change_pressed(self):
    if self.Change.isChecked():
        self.Change.setText("🧮")
        self.Clear.setStyleSheet("QPushButton {\n"
                                 "  background-color: RGB (107, 128, 104) ;\n"
                                 "  border: 1px solid gray;\n"
                                 "}\n"
                                 "QPushButton:pressed {\n"
                                 "    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,\n"
                                 "                                      stop: 0 #BEBEBE, stop: 1 #D7D7D7);\n"
                                 "}")

    else:
        self.Change.setText("💰")
        self.Clear.setStyleSheet("QPushButton {\n"
                                 "  background-color: rgb(215, 215, 215);\n"
                                 "  border: 1px solid gray;\n"
                                 "}\n"
                                 "QPushButton:pressed {\n"
                                 "    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,\n"
                                 "                                      stop: 0 #BEBEBE, stop: 1 #D7D7D7);\n"
                                 "}")

And if you have to keep code in separated functions then you could use self.changeMode instead of global variable. And also run Clear_changed() in `Change_pressed()

def Change_pressed(self):
    self.changeSymbol()
    self.Clear_changed()
    
def changeSymbol(self):
    if self.Change.isChecked():
        self.Change.setText("🧮")
        self.changeMode = True
    else:
        self.Change.setText("💰")
        self.changeMode = False

def Clear_changed(self):
    if self.changeMode == True:
        self.Clear.setStyleSheet("QPushButton {\n"
                                 "  background-color: RGB (107, 128, 104) ;\n"
                                 "  border: 1px solid gray;\n"
                                 "}\n"
                                 "QPushButton:pressed {\n"
                                 "    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,\n"
                                 "                                      stop: 0 #BEBEBE, stop: 1 #D7D7D7);\n"
                                 "}")
    else:
        self.Clear.setStyleSheet("QPushButton {\n"
                                 "  background-color: rgb(215, 215, 215);\n"
                                 "  border: 1px solid gray;\n"
                                 "}\n"
                                 "QPushButton:pressed {\n"
                                 "    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,\n"
                                 "                                      stop: 0 #BEBEBE, stop: 1 #D7D7D7);\n"
                                 "}")
