your code may be structured in a way suitable for try/except wrapping. After the try clause, we can have one or many except clauses that define
The optional else clause is executed if and when control flows off the end of the try clause.7.2 Exceptions in the else clause are not handled by the preceding except clauses. Currently, control ``flows off the end'' except in the case of an exception or the execution of a return, c...
From time to time in Python, I see the block:在Python中,我不时看到该块: try: try_this(whatever) except SomeException as exception: #Handle exception else: return something 1. 2. 3. 4. 5. 6. What is the reason for the try-except-else to exist?try-except-else存在的原因是什么?
Try, Except, else and Finally in PythonAdditionally, have an else clause, which is executed if no exceptions are raised during the file operations. In this case, you can print a message indicating that the file was opened successfully. Also have a finally clause, which is always executed ...

下面是一个更加复杂的例子(在同一个 try 语句里包含 except 和 finally 子句): >>>def divide(x, y): try: result = x / y except ZeroDivisionError: print("division by zero!") else: print("result is", result) finally: print("executing finally clause") >>> divide(2, 1) result is 2.0...

We believe this should be fixed upstream in Python itself until that we remove support fortry/except*from RestrictedPython. (It has been fixed for some Python versions.) Patches Patched in version 8.0 by removing support fortry/except*clauses ...
