Runtime Error Python Example
4 except ZeroDivisionError: 5 print "divide by zero" If you wanted to examine python runtime error could not open display the exception from code, you could have: 1 (x,y) = (5,0) 2 try: 3 z = x/y 4

Is there any way to differentiate between this RuntimeError and others that might be raised? If the error is caused by a specific condition, then I think the easiest way to catch the error is to test for the condition, and you can raise a more specific error yourself. After all the 'error' exists before the error is thrown, since in this case its a problem with the environment. I agree with those above - text matching on an error is kind of a t

The command line gives Floating point exception: 8.

When calling non-Python APIs, you're the only one with the information required to create the exceptions. –ShadowRanger Mar 8 at 3:09 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted Now sit back and remember what C code looks like at runtime. It's just compiled to machine code. When you divide by zero in it, it happens on machine code level - i.e. the CPU actually attempts it, generates a hardware interrupt which the OS handles and ultimately terminates your process. Python code, on the other hand, is just random binary data at runtime that another code - the interpreter - looks at and determines what to do. When you divide by zero in it, the interpreter double-checks the divisor and prints a nice traceback before the CPU actually attempts the ope
