Exception Handling in Python

Posted by codingtag on September 10th, 2019

It becomes very essential to handle such exceptions in Python so that the flow of code execution is not hindered. Upon negligence of such exceptions, all the code which follows the erroneous code will also be stopped, resulting in complete failure of execution.

If you are preparing for Python and want to learn which types of questions related to exceptions are asked while interview, you can see Python Interview Questions.  So, what are the ways in which exceptions are handled while working with Python? Let us find out.

Handling Exceptions in Python

In Python, exceptions are handled with the use of a try block. The code which is auspicious is placed in the try block.

· Try-Except

The try block is then followed by the except block which contains the code to handle the exception if found in the try block.

The basic syntax for try block is:

try:  

#block of code   

except Exception1:  

#block of code  

· Try-Else

We can also include the Else block in the above code which will specify the code to run if there is no exception found:

try:  

#block of code   

except Exception1:  

#block of code  

Else:

#block of code

· Try-Finally

We can also add the Finally block in Python exception handling which includes the compulsory code which must be executed every time the code runs and before the try block will throw the exception:

try:  

#block of code   

except Exception1:  

#block of code  

Else:

#block of code

Finally:

#block of code(always runs)

Summary

So, that was an overview of how exceptions are handled using try-except in Python. You can also see MySQL Interview Questions to gain more insight into Python concepts. Some points which we covered in this blog are:

• Exceptions are erroneous code which abrupt the code execution.
• Exceptions must be handled to prevent the following codes to be hindered.
• Try block is used to handle exceptions in Python.
• The Except block is used to include the code which will be executed when an exception is found in the try block code.
• The Else block includes the code which will be executed if there is no exception thrown by try block code.
• The Finally block includes the important code which gets executed every time the code runs and before the try block throws an exception.
