Exceptions and Errors Handling
When creating a program we can make mistakes that end with errors and the worst programs we make stop running,
it would be even more annoying if we could not find errors in the code that we made or what was wrong.
In simple words, errors are something that programmers avoid in making a program.
To solve this problem in python we can use
try: print("this is not a string " + 1) except: print("error") >>> error
And if you want to get error messages in more detail from your code, you can add arguments
except Exception as err
try: print("this is not a string " + 1) except Exception as err: print("error:\n" + str(err)) >>> error: >>> must be str, not int
Two additional clauses for the try-except statement are
else clause executes when the program runs successfully without any error. While the
finally clause will always execute no matter what:
try: print("this is a " + "string") except Exception as err: print("error:\n" + str(err)) else: print("successfully concatenated string") finally: print("end execution") >>> this is a string >>> successfully concatenated string >>> end execution
