This is the first time that I try to use threads on any programming language. I am learning PySide2 so I tried there.

Note: I removed from __init__ all the window information related to buttons, lines and UI as I consider this snippet is big enough already.

Please let me know if this is the correct way to create a Qthread. Also, please let me know if my docstrings are wrong, and how to improve them.

from time import sleep
from PySide2.QtCore import QThread, SIGNAL
from PySide2 import QtWidgets

class MainForm(QtWidgets.QMainWindow, Ui_MainWindow):
 """Main window of the program."""
 def __init__(self, parent=None):
 QtWidgets.QMainWindow.__init__(self, parent)
 self.setupUi(self)
 self.thread_stats_start()

 def thread_stats_start(self):
 """Create a secondary thread that deals with stats"""
 self.THREAD_STATS = ProjectStats()
 self.connect(self.THREAD_STATS, SIGNAL("thread_stats_update(QString)"), self.thread_stats_update)
 self.THREAD_STATS.start()

 def thread_stats_update(self, value):
 """Update the value when you receive the signal"""
 current_seconds = alexfunctions.parse_seconds(self.line_ProjectTime.text(), reverse=True)
 new_seconds = alexfunctions.parse_seconds(current_seconds + int(value))
 self.line_ProjectTime.setText(str(new_seconds))

 def thread_stats_stop(self):
 """Stop the Threading and save the data."""
 if self.THREAD_STATS.isRunning():
 self.THREAD_STATS.terminate()
 self.save_stats()

class ProjectStats(QThread):
 """Thread class for Stats updating."""
 def __init__(self, parent=None):
 QThread.__init__(self, parent)

 def run(self):
 """Run the main loop and choose what to send to the main thread"""
 while True:
 self.emit(SIGNAL('thread_stats_update(QString)'), "1")
 sleep(1)

Edit: I forgot to add my parse_seconds method.

def parse_seconds(seconds, reverse=False):
 """Transform seconds into a more valid data
 Seconds must be integer for normal mode
 Seconds must have <1d, 1h, 1m, 1s> sintax for reverse mode"""
 if reverse:
 d, h, m, s = seconds.split(", ")
 d = int(d[:-1]) * 86400
 h = int(h[:-1]) * 3600
 m = int(m[:-1]) * 60
 s = int(s[:-1])
 return s + m + h + d
 else:
 m, s = divmod(seconds, 60)
 h, m = divmod(m, 60)
 d, h = divmod(h, 24)
 return "0d, 1h, 2m, 3s".format(d, h, m, s)
