I have written a python code where with each button press I'm executing my work with the help of 2 threads. eg.
Press button 1 -> Thread-1 and Thread-2 will do the job
Press button 2 -> Thread-3 and Thread-4 will do the job
Press button 3 -> Thread-5 and Thread-6 will do the job
Whenever button is pressed, till the moment it does't print the o/p on screen, button displays 'WIP'(Work In Progress)
I want to modify it further, When any of the button is pressed I don't want the user to press more buttons when one button is in progress(WIP). So other threads shouldn't be created before the currently working two are terminated. How should I do this?
I'm giving here my code for reference:

import sys, os, time

class LearnButton(QPushButton):
def __init__(self, title, test):
super(QPushButton, self).__init__()
self._title = title
self._test = test
self.setText(title)
self.clicked.connect(self.click_threads)
self._q = Queue.Queue()
self.flag = True
def click_threads(self):
self.thread1 = threading.Thread(target=self.fun1)
self.thread2 = threading.Thread(target=self.fun2)

self.thread2.start()

print self.date_time_string
self.flag = False

self.setEnabled(False)
while self.thread1.isAlive():
self.setText('WIP')
time.sleep(0.5)

self.setText(self._title)
class LearnApp(QDialog):
def __init__(self):
super(QDialog, self).__init__()
self.setWindowTitle("LearnApp")
close_button = QPushButton("Close")
close_button.clicked.connect(self.close)
self.button1 = LearnButton("B1", "Im in B1")
self.button2 = LearnButton("B2", "Im in B2")
self.button3 = LearnButton("B3", "Im in B3")
self.test_report = QTextEdit()
self.test_report.setReadOnly(True)
layout = QHBoxLayout()
sub_layout = QVBoxLayout()
sub_layout.addWidget(self.button1)
sub_layout.addWidget(self.button2)
sub_layout.addWidget(self.button3)
sub_layout.addWidget(close_button)
layout.addLayout(sub_layout)
layout.addWidget(self.test_report)
self.setLayout(layout)
self.setFocus()
app = QApplication(sys.argv)
dialog = LearnApp()
dialog.show()
app.exec_()
