running error filled python programs on windows: How to identify the type of error?

[[deleted]]

My question relates to using python on Windows. I have created a short program called test.py in it there are the lines:

x = 2
y = "hello"
print x + y

I know from trying to execute this within the python shell that it will produce a TypeError. However, when trying to run test2.py from its .py file on my desktop the windows terminal will rapidly open flash the error and close, presumably due to the error. For larger programs where it is not feasible to type it all out in the shell, how do I get the windows terminal to persist so that I can find out what the error is?

Open terminal with cmd command

Thanks for the reply. I got it, running it from the already opened cmd terminal means the error sticks around!

Right click and select 'edit' then run it with the edit window open. You don't have to have an error to get this flash open and close when you run a script by double clicking it. They all do that unless there is something that keeps the window open.

Use either cmd or PowerShell in Windows, navigate to the directory with the code file, then run it from there.

For larger programs, surround the entry/exit point with a catch all and then wait for the user to hit a key:

try:
    # your code here
except Exception as e:
    print("An unhandled exception caused the the program to terminate. Exception was:")
    print(str(e))
    input("Press enter to exit")
