Python Try Except :

The try block lets you test a block of code for errors. The except block lets you handle the error. The finally block lets you execute code, regardless of the result of the try- and except blocks.

Exception Handling :

When an error occurs, or exception as we call it, Python will normally stop and generate an error message. These exceptions can be handled using the try statement:

Example :

#The try block will generate an exception, because x is not defined try: print(x) except: print("An exception occurred") input()

Output :

Many Exceptions :

You can define as many exception blocks as you want, e.g. if you want to execute a special block of code for a special kind of error. So, print one message if the try block raises a NameError and another for other errors :

try: print(x) except NameError: print("Variable x is not defined") except: print("Something else went wrong") input()

Output :

Finally :

The finally block, if specified, will be executed regardless if the try block raises an error or not.

Example :

try: print(x) except: print("Something went wrong") finally: print("The 'try except' is finished") input()

Output :
