Catching Specific Exceptions in Python For eachtryblock, there can be zero or moreexceptblocks. Multipleexceptblocks allow us to handle each exception differently. The argument type of eachexceptblock indicates the type of exception that can be handled by it. For example, ...
Perhaps you could try handling this exception as well. Up to this point, you’ve learned several ways of dealing with multiple possible exceptions. However, you’ve only ever caught one out of the bunch. In the final section, you’ll learn how to catch each member in a group of ...
The division by zero is caught by the inner 'except', while the outer 'except' catches an index error, showing how to manage multiple potential exceptions in different parts of the code.Code:try: # Outer try block try: # Attempt to divide by zero result = 10 / 0 except ...
