goto in Python

By: Python Documentation Team Viewed: 1388 times  Printer Friendly Format    

You can use exceptions to provide a 'structured goto' that even works across function calls. Many feel that exceptions can conveniently emulate all reasonable uses of the 'go' or 'goto' constructs of C, Fortran, and other languages. For example:

class label: pass  # declare a label

     if (condition): raise label()  # goto label
except label:  # where to goto

This doesn’t allow you to jump into the middle of a loop, but that’s usually considered an abuse of goto anyway. Use sparingly.
