If you're getting an error, and want to handle it safely, then you're looking for exception handling: https://docs.python.org/3/tutorial/errors.html
>>> def i_always_fail():
... print("here we go!")
... raise Exception("dead")
...
>>> i_always_fail()
here we go!
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in i_always_fail
Exception: dead
>>> try:
... i_always_fail()
... except Exception as err:
... print("Error happened: {}".format(err))
...
here we go!
Error happened: dead
