My main goal: Automating Zoom
my zoomModule.py file is:
import os, pywinauto
from pywinauto import Desktop
from pywinauto import findwindows
from pywinauto.application import Application
from pywinauto.keyboard import send_keys
# Create a instance of Application()
app = Application(backend="uia")
def get_Zoom_Main_Window():
"""starts and connect to zoom main window"""
zoom_exe_path = os.path.join(
os.environ["USERPROFILE"], "AppData", "Roaming", "Zoom", "bin", "Zoom.exe"
)
try:
print("starts and connect to zoom main window")
start = app.start(
zoom_exe_path,
timeout=100,
)
print("1. Zoom Started")
connected = start.connect(title="Zoom", timeout=5)
print("1. Zoom Connected")
return connected
except (
pywinauto.findwindows.ElementNotFoundError,
pywinauto.timings.TimeoutError,
) as e:
print("Err_context before 2nd try: ", e.__context__)
try:
print("Second try")
start = app.start(
zoom_exe_path,
timeout=100,
)
print("2. Zoom started")
connected = start.connect(title="Zoom - Not connected", timeout=20)
print("2. Zoom connected")
return connected
except (
pywinauto.findwindows.ElementNotFoundError,
pywinauto.timings.TimeoutError,
) as err:
print(err.__context__)
print("Unknown Problem; Check internet connection and try again!")
def open_join_meeting_window():
"""opens the Join Meeting Popup Window; returns the Join Meeting Window"""
zoomMainWin = get_Zoom_Main_Window()
zoomMainWin["Zoom"].child_window(
title="Home", control_type="TabItem"
).wrapper_object().click_input()
zoomMainWin["Zoom"].child_window(
title="Join", control_type="Button"
).wrapper_object().click_input()
try:
joinMeetingWin = app.connect(title="Join Meeting", timeout=15)
print("Connected to Join Meeting Window.")
except (findwindows.ElementNotFoundError, pywinauto.timings.TimeoutError) as e:
print("Err before joinMeetingWin: ", e)
pass
# joinMeetingWin['Join Meeting']
hek = open_join_meeting_window()
print("Haa! out of the function")
Terminal, when I run the above file:
PS D:\PythonDevelopment\my_CLI_tools> python zoomModule.py
starts and connect to zoom main window
1. Zoom Started
1. Zoom Connected
Err before joinMeetingWin:
Haa! out of the function
PS D:\PythonDevelopment\my_CLI_tools>
See how e does not get printed or remain blank after Err before joinMeetingWin: in the open_join_meeting_window().
The same happens for the try-except block inside the get_Zoom_Main_Window()
I have looked for help in google, but in vain.
Minimum expectation: I can print() the errors raised by pywinauto to the console/terminal without crashing my code.
More expectation: I can avoid try-except blocks in my code if possible. Implement better way of finding and connecting to the required window, getting hold of child_window() and switching between open windows.
My approach may be wrong. In that case please show me the correct procedure.
Seems like I have figured out how to print() the errors raised by pywinauto to the console/terminal without crashing my code with the help of this answer.

First, the traditional traceback is printed. Then the name of the error raised by pywinauto is used in the control-flow to decide what to do.
