Errors are caused by syntactical or logical mistakes in the code, while exceptions are caused by unexpected events or conditions that occur during program execution.<\/p>\n\n\n\n<p>Here are some common types of errors and exceptions in Python:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Syntax Errors<\/h3>\n\n\n\n<p>Syntax errors occur when the code violates Python&#8217;s syntax rules. For example, forgetting a colon after an <code>if<\/code> statement or misspelling a variable name can result in a syntax error.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code># Syntax error example\nif x == 5\n    print(\"x is 5\")\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Name Errors<\/h3>\n\n\n\n<p>Name errors occur when the code tries to use a variable or function name that has not been defined. This can occur if a variable is misspelled or if it has not been assigned a value.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code># Name error example\nprint(my_variable)\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Type Errors<\/h3>\n\n\n\n<p>Type errors occur when the code tries to perform an operation on incompatible types. For example, trying to add a string and an integer together will result in a type error.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code># Type error example\nmy_string = \"hello\"\nmy_number = 5\nprint(my_string + my_number)\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Value Errors<\/h3>\n\n\n\n<p>Value errors occur when the code tries to perform an operation on a variable with an inappropriate value. For example, trying to convert a string that cannot be converted to a number will result in a value error.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code># Value error example\nmy_string = \"hello\"\nmy_number = int(my_string)\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Index Errors<\/h3>\n\n\n\n<p>Index errors occur when the code tries to access an element of a sequence that does not exist. For example, trying to access the 10th element of a list with only 5 elements will result in an index error.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code># Index error example\nmy_list = [1, 2, 3, 4, 5]\nprint(my_list[10])\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Attribute Errors<\/h3>\n\n\n\n<p>Attribute errors occur when the code tries to access an attribute or method of an object that does not exist. For example, trying to access a non-existent method of a string object will result in an attribute error.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code># Attribute error example\nmy_string = \"hello\"\nmy_string.some_method()\n<\/code><\/pre>\n\n\n\n<p>To handle exceptions in Python, you can use the <code>try<\/code>&#8211;<code>except<\/code> statement. This allows you to catch and handle exceptions that may occur during program execution, so that your program can gracefully recover from them.<\/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>Errors and exceptions In Python, errors and exceptions are two types of issues that can occur during the execution of a program.
