The main function of these keywords is to define the syntax of the programming language.<\/li>\n\n\n\n<li>All identifiers in the same scope will be distinct.<\/li>\n\n\n\n<li>Use of the combination of lowercase characters (a-z), uppercase characters (A-Z), digital(0-9), and underscore characters while naming identifiers.<\/li>\n\n\n\n<li>Identifiers in Python are case-sensitive. Eg: &#8221;myPet&#8221; and &#8221;my pet&#8221; are different.<\/li>\n\n\n\n<li>Special characters such as @,$, %,&amp;,*, and # cannot be used in identifier names.<\/li>\n\n\n\n<li> Identifiers must begin with a  non-numeric character. The underscore can be the first character of the identifier name.<\/li>\n\n\n\n<li> length of the identifier name can vary.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"example-of-a-valid-python-identifier\">Example of a Valid Python Identifier<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>my_variable = 42\nmy_function = lambda x: x * 2\nMyClass = type('MyClass', (object,), {'attribute': 'value'})\n<\/code><\/pre>\n\n\n\n<p>In this example, we have three valid identifiers:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><code>my_variable<\/code>: Identifies a variable holding the value 42.<\/li>\n\n\n\n<li><code>my_function<\/code>: Identifies a lambda function that doubles its input.<\/li>\n\n\n\n<li><code>MyClass<\/code>: Identifies a dynamically created class with an attribute named <code>'attribute'<\/code>.<\/li>\n<\/ol>\n\n\n\n<p>Remember that Python is case-sensitive, so <code>my_variable<\/code> and <code>My_Variable<\/code> would be considered as two different identifiers. Additionally, you should avoid using reserved keywords like <code>if<\/code>, <code>else<\/code>, <code>while<\/code>, etc., as identifiers, as they have specific meanings in the Python language and cannot be used as variable names.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faq-is-python-case-sensitive-when-dealing-with-identifiers\">FAQ-Is Python Case sensitive when dealing with identifiers<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1690806844882\" class=\"rank-math-list-item\">\n<h4 class=\"rank-math-question \">Q1.
