PyQt5按钮背景色不起作用

Question

Here is the button's code:

    self.pushButton.setFont(font)
    self.pushButton.setStyleSheet("background-color: qlineargradient(spread:pad, x1:0.0568182, y1:0.126, x2:0.75, y2:0.227, stop:0.0738636 rgba(0, 255, 0, 255), stop:0.840909 rgba(0, 136, 0, 255));\n")
    self.pushButton.setFlat(True)
    self.pushButton.setObjectName("pushButton")

Although I set a background gradient to this button, it's not taking effect.

Here's the button normally:

Here's when it's pressed down:
