I am running a python code with a for loop iteration within a for loop, the code is working however, if an exception is thrown the code to execute under exception is not executing and the code loops inifinitely within the except without moving to the main loop

Error Message below:

selenium.common.exceptions.NoSuchWindowException: Message: no such window: target window already closed
from unknown error: web view not found
 (Session info: chrome=73.0.3683.86)
 (Driver info: chromedriver=73.0.3683.68 (47787ec04b6e38e22703e856e101e840b65afe72),platform=Windows NT 10.0.17763 x86_64)

Code that I tried:

for _ in range(100):
 print("main loop pass")
 for button in fb_buttons:
 driver.switch_to.window(driver.window_handles[1])

 try:
 while like_right:
 for right in like_right:
 right.click()
 break
 driver.switch_to.window(driver.window_handles[0])


 except (NoSuchWindowException, ElementNotVisibleException, StaleElementReferenceException) as e:

 driver.switch_to.window(driver.window_handles[0])
 continue
 except StaleElementReferenceException as e:
 time.sleep(10)
 refresh.click()
 else:
 time.sleep(5)
 refresh.click()
 print("refreshed")

Googling/documentation came up with nothing...and it strikes me as strange that selenium is fine throwing an exception but can't catch it.

This break below renders the following line unreachable:

break
driver.switch_to.window(driver.window_handles[0]) # <--- unreachable

Here is a small example of what you might be going for, note this code throws:

sequence = ['first', 'second', 'third']

def run_after_type_error_exception():
 print("runs after type error")

def run_after_index_error_exception():
 print("runs after index error")

Without breaks this code will catch both exceptions on the first iteration. Here you also have a for-else block. Note, that after the third iteration this code will Do something else.

for iteration in range(5):
 for element in sequence:
 try:
 while sequence:
 for character in element:
 sequence.pop()
 sequence[1].split() + 1
 except (NameError, TypeError, ValueError) as e:
 print(f"Caught first exception: e")
 run_after_type_error_exception()
 # break
 except IndexError as e:
 print(f"Caught exception e")
 run_after_index_error_exception()
 # break
 else:
 print("Do something else")
 print(f"Current iteration: iteration")

Also, note time.sleep(is_in_seconds) so if your code behaves similarly to the above code (where it's in the else portion ~half of the time), then you'll be sleeping for ~4 minutes at least...
