threading.current_thread().name

`threading.current_thread().name` 是 Python 中 `threading` 模块中的一个属性，用于获取当前线程的名字。当你在一个多线程环境中，通过 `current_thread()` 函数可以获取到运行当前代码的线程对象，然后 `.name` 属性会返回该线程所设置的名字，如果没有显式设置名字，默认是一个默认的名称。

例如，如果你创建了一个线程并设置了名字：

import threading

def worker():
    print(threading.current_thread().name)

my_thread = threading.Thread(target=worker, name="MyThread")
my_thread.start()

这里 `my_thread.name` 将会被设置为 "MyThread"，而当它开始运行并在主线程中打印时，将显示 "MyThread"。

这是一段Python代码，通过使用import关键字导入了sys、threading、time等模块。同时，也导入了PyQt5.QtWidgets的部分类和PyQt5.uic模块。此外，还导入了pandas和random模块，用于处理数据和生成随机数等操作。
