Identifiers and Keywords are similar terms used in computer languages while writing code.<\/p>\n<p>So in this article, we are going to discuss two important Python programming elements, which are known as Keywords and Identifiers.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Keywords_in_Python\"><\/span>Keywords in Python<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/tutorpython.com\/tutorial\/keywords-identifiers-in-python\">Keywords in Python<\/a> are special predefined and reserved words that are used to perform a certain task.<\/p>\n<p>Every programming language has them.<\/p>\n<p>These cannot be used to declare a function, variable, or identifier.<\/p>\n<p>These are very easy to understand and we do not need to import them into our code.<\/p>\n<p>All keywords in Python are case-sensitive.<\/p>\n<p>They are written in lowercase except for the <strong>True<\/strong>, <strong>False,<\/strong> and <strong>None<\/strong> keywords.<\/p>\n<p>There are over 30 keywords in Python 3. Some of the important keywords in Python are:<\/p>\n<ul>\n<li><strong>and<\/strong> &#8211; a <a href=\"https:\/\/tutorpython.com\/tutorial\/types-of-operators-in-python\" target=\"_blank\" rel=\"noopener\">logical operator<\/a> that returns true if both the operands are true or else returns false.<\/li>\n<li><strong>break<\/strong> &#8211; used to break from a loop.<\/li>\n<li><strong>continue<\/strong> &#8211; used to continue to the next iteration of a loop.<\/li>\n<li><strong>def<\/strong> &#8211; used to <a href=\"https:\/\/tutorpython.com\/tutorial\/functions-in-python\" target=\"_blank\" rel=\"noopener\">define a function<\/a>.<\/li>\n<li><strong>elif<\/strong> &#8211; condition statement used for the <a href=\"https:\/\/tutorpython.com\/tutorial\/if-else-python\" target=\"_blank\" rel=\"noopener\">else if condition<\/a>.<\/li>\n<li><strong>else<\/strong> &#8211; conditional statement that is executed if the &#8220;if condition&#8221; is false.<\/li>\n<li><strong>except<\/strong> &#8211; Used in <a href=\"https:\/\/tutorpython.com\/tutorial\/exception-handling-in-python\" target=\"_blank\" rel=\"noopener\">exceptions<\/a>.<\/li>\n<li><strong>finally<\/strong> &#8211; used with exceptions to execute a block of code that will be executed no matter if there is an exception or not.<\/li>\n<li><strong>for<\/strong> &#8211; Used in <a href=\"https:\/\/tutorpython.com\/tutorial\/for-loops-in-python\" target=\"_blank\" rel=\"noopener\">for loop<\/a>.<\/li>\n<li><strong>global<\/strong> &#8211; Used to declare a <a href=\"https:\/\/tutorpython.com\/tutorial\/variable-scope-in-python\" target=\"_blank\" rel=\"noopener\">global variable<\/a>.<\/li>\n<li><strong>if<\/strong> &#8211; a conditional statement that executes if the condition is true.<\/li>\n<li><strong>return<\/strong> &#8211; used to exit a function and return a value.<\/li>\n<li><strong>try<\/strong> &#8211; used to make a try-except statement.<\/li>\n<li><strong>while<\/strong> &#8211; used in the while loop.<\/li>\n<\/ul>\n<p>There are several excellent <strong>Python IDEs<\/strong> available. Each of these will highlight certain terms in your code to make them stand out from other ones.<\/p>\n<p>This will enable you to recognize Python <strong>keywords<\/strong> while you&#8217;re working rapidly and avoid using them improperly.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Identifiers_in_Python\"><\/span>Identifiers in Python<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/tutorpython.com\/tutorial\/keywords-identifiers-in-python\">Python identifiers<\/a> are user-defined names given to <a href=\"https:\/\/tutorpython.com\/tutorial\/variables-in-python\" target=\"_blank\" rel=\"noopener\">variables<\/a>, <a href=\"https:\/\/tutorpython.com\/tutorial\/functions-in-python\" target=\"_blank\" rel=\"noopener\">functions<\/a>, <a href=\"https:\/\/tutorpython.com\/tutorial\/object-oriented-programming-in-python\" target=\"_blank\" rel=\"noopener\">classes<\/a>, modules, or other entities.<\/p>\n<p>Identifiers are case-sensitive in Python since it is a case-sensitive computer programming language.<\/p>\n<p><strong>Variable and identifier are sometimes mistakenly thought to be the same thing, however, they are separate.<\/strong><\/p>\n<p>Identifiers should have meaningful names to make the code more readable.<\/p>\n<p>Also, we cannot use <strong>keywords<\/strong> as variable names as they are reserved built-in names in Python.<\/p>\n<p><strong>Rules to Name Identifiers:<\/strong><\/p>\n<ol>\n<li>Identifiers are a combination of digits, letters, and underscore( _ ) that can be written in either uppercase or lowercase.<\/li>\n<li>Keywords are not allowed to be identifiers.<\/li>\n<li>Identifiers are not allowed to be starting with numbers or digits.<\/li>\n<li>Special symbols such as !, @, #, $, %, etc cannot be used.<\/li>\n<li>Identifiers are also case-sensitive and they are not allowed to have white spaces.<\/li>\n<\/ol>\n<p>If any of the above-stated rules are not followed, then the compiler will return a <strong>SyntaxError<\/strong>.<\/p>\n<p>Hope you like the tutorial on keywords and identifiers in Python.
