What is the difference between calling sys.exit() and throwing an exception in Python? Let's say I have a Python script which does the following: open a file read lines close it If the file doesn't exist or an IOException gets thrown at runtime, which of the options below makes more sense? no except/catch of the exception, if exception occurs, it fails out (which is expected behaviour anyway) except/catch the exception, logs the error message, throw customized exception by myself, fails out. in an except IOException block, exit with an error message e.g. sys.exit("something is wrong") Does option 3 kill the process while 1 and 2 do not? What's the best way to handle the Python exceptions given that Python doesn't have a checked exception like Java (I am really a Java developer ^_^)?
