An exception is a signal that an error or exceptional condition has occurred that needs to be handled.<\/p>\n\n\n\n<p>When an exception occurs, Python stops executing the current function and looks for a suitable exception handler to handle the exception. If no suitable exception handler is found, the program terminates and displays an error message.<\/p>\n\n\n\n<p>Here&#8217;s an example of how to use a <code>try<\/code>&#8211;<code>except<\/code> block to catch and handle an exception:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>try:\n    x = 10 \/ 0\nexcept ZeroDivisionError:\n    print(\"Division by zero!\")\n<\/code><\/pre>\n\n\n\n<p>In the above example, the <code>try<\/code> block contains the code that may raise an exception, which is dividing the number 10 by zero. The <code>except<\/code> block specifies the type of exception to catch, which in this case is <code>ZeroDivisionError<\/code>. If an exception of this type is raised, the <code>except<\/code> block will execute, which in this case prints a message to the console.<\/p>\n\n\n\n<p>You can also catch multiple exceptions with a single <code>except<\/code> block:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>try:\n    # some code that may raise an exception\nexcept (ExceptionType1, ExceptionType2) as e:\n    # handle the exception\n<\/code><\/pre>\n\n\n\n<p>In the above example, the <code>except<\/code> block catches two types of exceptions, <code>ExceptionType1<\/code> and <code>ExceptionType2<\/code>, and assigns the exception to the variable <code>e<\/code>.<\/p>\n\n\n\n<p>You can also use the <code>finally<\/code> block to specify code that should be executed whether or not an exception is raised:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>try:\n    # some code that may raise an exception\nexcept:\n    # handle the exception\nfinally:\n    # code to execute whether or not an exception is raised\n<\/code><\/pre>\n\n\n\n<p>In the above example, the <code>finally<\/code> block specifies code that will always be executed, whether or not an exception is raised.<\/p>\n\n\n\n<p>You can raise your own exceptions using the <code>raise<\/code> statement:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>if x &lt; 0:\n    raise ValueError(\"x cannot be negative\")\n<\/code><\/pre>\n\n\n\n<p>In the above example, the <code>raise<\/code> statement is used to raise a <code>ValueError<\/code> exception if <code>x<\/code> is less than zero, along with a message that explains the reason for the exception.<\/p>\n\n\n\n<p>Overall, exceptions in Python provide a powerful mechanism for handling errors and exceptional conditions in your code.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Apply for Python Certification!<\/strong><\/h3>\n\n\n\n<p><a href=\"https:\/\/www.vskills.in\/certification\/certified-python-developer\">https:\/\/www.vskills.in\/certification\/certified-python-developer<\/a><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><a href=\"https:\/\/www.vskills.in\/certification\/tutorial\/python-developer\/\" target=\"_blank\" rel=\"noreferrer noopener\">Back to Tutorials<\/a><\/strong><\/h4>\n","protected":false},"excerpt":{"rendered":"<p>Exceptions in python In Python, exceptions are a way to handle errors that occur during the execution of a program.
