Python -设计一个滑块来控制函数的输入

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QSlider, QVBoxLayout
from PyQt5.QtCore import Qt

class SliderExample(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.setWindowTitle('Slider Example')

        # 创建标签和滑块
        self.label = QLabel('0')
        self.slider = QSlider(Qt.Horizontal)
        self.slider.setMinimum(0)
        self.slider.setMaximum(100)
        self.slider.valueChanged.connect(self.updateLabel)

        # 创建布局并添加标签和滑块
        layout = QVBoxLayout()
        layout.addWidget(self.label)
        layout.addWidget(self.slider)

        self.setLayout(layout)
        self.show()

    def updateLabel(self, value):
        self.label.setText(str(value))

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = SliderExample()
    sys.exit(app.exec_())
