python将css渐变色转换成qss渐变色

可以使用 Python 编写一个函数来将 CSS 渐变色转换成 QSS 渐变色。下面是一个 Python 函数的示例代码：

def css_gradient_to_qss(css_gradient):
    """
    Convert CSS gradient to QSS gradient
    """
    qss_gradient = ""
    gradient_type = css_gradient.split("(")[0].strip()  # get gradient type
    if gradient_type == "linear-gradient":
        qss_gradient = "qlineargradient("
        gradient_direction = css_gradient.split("(")[1].split(")")[0].strip()  # get gradient direction
        if gradient_direction == "to top":
            qss_gradient += "x1: 0, y1: 1, x2: 0, y2: 0"
        elif gradient_direction == "to right":
            qss_gradient += "x1: 0, y1: 0, x2: 1, y2: 0"
        elif gradient_direction == "to bottom":
            qss_gradient += "x1: 0, y1: 0, x2: 0, y2: 1"
        elif gradient_direction == "to left":
            qss_gradient += "x1: 1, y1: 0, x2: 0, y2: 0"
        else:
            # unsupported direction
            return ""
        gradient_colors = css_gradient.split("(")[1].split(")")[1].split(",")  # get gradient colors
        for i, color in enumerate(gradient_colors):
            color = color.strip()
            if color.startswith("#"):
                # hex color
                qss_gradient += ", stop: %s %s" % (i / (len(gradient_colors) - 1), color)
            else:
                # named color
                qss_gradient += ", stop: %s %s" % (i / (len(gradient_colors) - 1), colorname_to_hex(color))
    elif gradient_type == "radial-gradient":
        qss_gradient = "qradialgradient("
        gradient_shape = css_gradient.split("(")[1].split(")")[0].split()[0].strip()  # get gradient shape
        if gradient_shape == "circle":
            qss_gradient += "cx: 0.5, cy: 0.5, radius: 0.5, fx: 0.5, fy: 0.5"
        elif gradient_shape == "ellipse":
            qss_gradient += "cx: 0.5, cy: 0.5, radius: 0.5, fx: 0.75, fy: 0.25"
        else:
            # unsupported shape
            return ""
        gradient_colors = css_gradient.split("(")[1].split(")")[1].split(",")  # get gradient colors
        for i, color in enumerate(gradient_colors):
            color = color.strip()
            if color.startswith("#"):
                # hex color
                qss_gradient += ", stop: %s %s" % (i / (len(gradient_colors) - 1), color)
            else:
                # named color
                qss_gradient += ", stop: %s %s" % (i / (len(gradient_colors) - 1), colorname_to_hex(color))
    else:
        # unsupported gradient type
        return ""
    qss_gradient += ")"
    return qss_gradient

这个函数可以将 CSS 渐变色转换成 QSS 渐变色，支持线性渐变和径向渐变，支持颜色名称和十六进制颜色值。需要注意的是，该函数中的 `colorname_to_hex(color)` 函数需要自行编写，用于将颜色名称转换成十六进制颜色值。
