帮我写一份用pyqt5做的显示冒泡排序的代码

好的，以下是一个使用PyQt5实现的冒泡排序可视化的代码示例：

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QLabel, QVBoxLayout
from PyQt5.QtGui import QPainter, QPen, QColor, QPixmap
from PyQt5.QtCore import Qt, QThread, pyqtSignal
import random
import time

class SortThread(QThread):
    sort_signal = pyqtSignal(list)

    def __init__(self, nums):
        super().__init__()
        self.nums = nums

    def run(self):
        for i in range(len(self.nums)):
            for j in range(len(self.nums)-i-1):
                if self.nums[j] > self.nums[j+1]:
                    self.nums[j], self.nums[j+1] = self.nums[j+1], self.nums[j]
                    self.sort_signal.emit(self.nums)

class BubbleSort(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('Bubble Sort')
        self.setGeometry(100, 100, 800, 600)

        self.nums = [random.randint(10, 500) for _ in range(50)]

        self.label = QLabel(self)
        self.label.setGeometry(0, 0, 800, 600)

        self.button = QPushButton('Start Sort', self)
        self.button.setGeometry(350, 550, 100, 30)
        self.button.clicked.connect(self.start_sort)

    def start_sort(self):
        self.button.setEnabled(False)
        self.thread = SortThread(self.nums)
        self.thread.sort_signal.connect(self.update_nums)
        self.thread.finished.connect(self.enable_button)
        self.thread.start()

    def enable_button(self):
        self.button.setEnabled(True)

    def update_nums(self, nums):
        self.nums = nums
        self.label.setPixmap(self.draw_pixmap())

    def draw_pixmap(self):
        pixmap = QPixmap(800, 600)
        pixmap.fill(Qt.white)

        painter = QPainter(pixmap)

        painter.setPen(QPen(QColor(0, 0, 0), 3, Qt.SolidLine))

        for i, num in enumerate(self.nums):
            painter.drawLine(50 + i*15, 550, 50 + i*15, 550-num)

        painter.end()

        return pixmap

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = BubbleSort()
    window.show()
    sys.exit(app.exec_())

这个程序会在GUI界面上随机生成50个数，并将其绘制成垂直线段。点击`Start Sort`按钮后，程序会启动一个新线程开始排序，同时在界面上更新显示，直到排序完成。这样就实现了一个简单的冒泡排序可视化程序。
