with Task() as bot:
File "/home/mank/PycharmProjects/botnew/bot/booking.py", line 14, in __init__
os.environ['PATH'] +=self.driver_path
TypeError: can only concatenate str (not "WebDriver") to str

Answer 1

self.driver_path is of type WebDriver but in your code it is treated like a string.
So your code fails in the line os.environ['PATH'] += self.driver_path - just removing the line should fix the current error message.
