PyQt5使动态窗口小部件可单击并将参数传递给另一个函数

我正在尝试制作动态小部件并使它们可单击。通过单击一个小部件，它应该将动态值传递给其他小部件。我尝试了sender（）和其他访问小部件的选项，但没有任何效果。所有小部件都从上一个小部件发送信息。

下面是代码：

import sys
from PyQt5.QtGui import QIcon, QPixmap
from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow, QPushButton, QLabel, QMessageBox,QSizePolicy, QLayoutItem,QFrame,QHBoxLayout, QGridLayout, QVBoxLayout
from PyQt5.QtCore import QCoreApplication,QSize,QFileInfo
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from functools import partial
from PyQt5.QtCore import pyqtSlot
import sip 


class Screen(QWidget):
    def __init__(self):

        super(Screen, self).__init__()

        self.running_layout = QVBoxLayout()
        self.action_layout = QVBoxLayout()
        self.layout = QHBoxLayout(self)
        self.layout.addLayout(self.running_layout)
        self.layout.addLayout(self.action_layout)
        self.setLayout(self.layout)
        self.show()
        self.all_running()        
        self.actions_1('1')
    def buttonClicked(self):      
        sender = self.sender()
        print(sender + ' was pressed')

    def all_running(self):
        for i in range(5):
            button = QLabel("btn "+str(i))
            button.mouseReleaseEvent = lambda _ : self.actions_1(str(button.text()).split()[1])
            self.running_layout.addWidget(button)


        button2 = QLabel("btn 5")
        button2.mouseReleaseEvent = lambda _ : self.actions_1(str(button2.text()).split()[1])        
        self.running_layout.addWidget(button2)


    def actions_1(self,value):

        while not self.action_layout.isEmpty():
            print(self.action_layout.isEmpty())
            widget = self.action_layout.itemAt(0).widget()
            print("removing", widget)
            widget.setVisible(False)
            self.action_layout.removeWidget(widget)
            del widget
        self.action_layout = QVBoxLayout()
        self.layout.addLayout(self.action_layout)
        val = int(value)

        for i in range(val):
            actions_item = QLabel(str(i))
            self.action_layout.addWidget(actions_item)

app = QApplication(sys.argv)
Gui = Screen()
sys.exit(app.exec_())

编辑：我试图基于一些小部件需要填充的int值将int传递给操作。此int基于我使用for循环生成的动态窗口小部件。例如，如果单击running_layout“ btn 0”的第一个小部件，则action_layout中将没有任何小部件，如果单击running_layout“ btn 1”的第二个小部件，则action_layout中将有一个小部件“ 0”，依此类推基于小部件编号。我能够发送信号，但是无论单击哪个动态创建的小部件，它都会将最后一个小部件“ btn 4”的值4发送到action_layout。
