python - Restart script on error -

so have script in selenium, crashes various reasons. fails click button, gets confused, gets messed , displays error.

how can command script, whenever crashes, re-run script beginning again? i've heard try , except functions i'm not sure how use them.

any appreciated! :)

generic answer retry on exception:

while true:    try:       # run selenium code breaks       pass    except exception e:       print("something went wrong: "+repr(e)) 

you may try refine exception type avoid retrying say, because of python error valueerror or ioerror. check exception type , change exception qualified type.
