These items can be of any data type: integers, strings, floats, or even other lists. Lists are enclosed in square brackets <code>[]<\/code> and each item within the list is separated by a comma. Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are\u00a0Tuple,\u00a0Set, and\u00a0Dictionary, all with different qualities and usage. <strong>For instance:<\/strong><\/p>\n\n\n\n<div class=\"wp-block-kevinbatdorf-code-block-pro padding-bottom-disabled cbp-has-line-numbers\" data-code-block-pro-font-family=\"Code-Pro-Fantasque-Sans-Mono\" style=\"font-size:.875rem;font-family:Code-Pro-Fantasque-Sans-Mono,ui-monospace,SFMono-Regular,Menlo,Monaco,Consolas,monospace;--cbp-line-number-color:#f6f6f4;--cbp-line-number-width:7.703125px;line-height:1.25rem\"><span style=\"display:block;padding:16px 0 0 16px;margin-bottom:-1px;width:100%;text-align:left;background-color:#282A36\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"54\" height=\"14\" viewBox=\"0 0 54 14\"><g fill=\"none\" fill-rule=\"evenodd\" transform=\"translate(1 1)\"><circle cx=\"6\" cy=\"6\" r=\"6\" fill=\"#FF5F56\" stroke=\"#E0443E\" stroke-width=\".5\"><\/circle><circle cx=\"26\" cy=\"6\" r=\"6\" fill=\"#FFBD2E\" stroke=\"#DEA123\" stroke-width=\".5\"><\/circle><circle cx=\"46\" cy=\"6\" r=\"6\" fill=\"#27C93F\" stroke=\"#1AAB29\" stroke-width=\".5\"><\/circle><\/g><\/svg><\/span><span role=\"button\" tabindex=\"0\" data-code=\"fruits = [&quot;apple&quot;, &quot;banana&quot;, &quot;orange&quot;, &quot;grape&quot;]\" style=\"color:#f6f6f4;display:none\" aria-label=\"Copy\" class=\"code-block-pro-copy-button\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" style=\"width:24px;height:24px\" fill=\"none\" viewBox=\"0 0 24 24\" stroke=\"currentColor\" stroke-width=\"2\"><path class=\"with-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M4.5 12.75l6 6 9-13.5\"><\/path><path class=\"without-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M16.5 8.25V6a2.25 2.25 0 00-2.25-2.25H6A2.25 2.25 0 003.75 6v8.25A2.25 2.25 0 006 16.5h2.25m8.25-8.25H18a2.25 2.25 0 012.25 2.25V18A2.25 2.25 0 0118 20.25h-7.5A2.25 2.25 0 018.25 18v-1.5m8.25-8.25h-6a2.25 2.25 0 00-2.25 2.25v6\"><\/path><\/svg><\/span><pre class=\"shiki dracula-soft\" style=\"background-color: #282A36\" tabindex=\"0\"><code><span class=\"line\"><span style=\"color: #F6F6F4\">fruits <\/span><span style=\"color: #F286C4\">=<\/span><span style=\"color: #F6F6F4\"> [<\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #E7EE98\">apple<\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #F6F6F4\">, <\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #E7EE98\">banana<\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #F6F6F4\">, <\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #E7EE98\">orange<\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #F6F6F4\">, <\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #E7EE98\">grape<\/span><span style=\"color: #DEE492\">&quot;<\/span><span style=\"color: #F6F6F4\">]<\/span><\/span><\/code><\/pre><span style=\"display:flex;align-items:flex-end;padding:10px;width:100%;justify-content:flex-end;background-color:#282A36;color:#ebebe6;font-size:12px;line-height:1;position:relative\">Python<\/span><\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><span class=\"ez-toc-section\" id=\"Types_of_Lists\"><\/span>Types of Lists<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/sahaldecode.com\/python-access-list-items\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/sahaldecode.com\/python-access-list-items\/\" rel=\"noreferrer noopener nofollow\">Access List Items<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/sahaldecode.com\/python-change-list-items\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/sahaldecode.com\/python-change-list-items\/\" rel=\"noreferrer noopener nofollow\">Change List Items<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/sahaldecode.com\/python-add-list-items\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/sahaldecode.com\/python-add-list-items\/\" rel=\"noreferrer noopener nofollow\">Add List Items<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/sahaldecode.com\/python-remove-list-items\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/sahaldecode.com\/python-remove-list-items\/\" rel=\"noreferrer noopener nofollow\">Remove List Items<\/a><\/li>\n\n\n\n<li>Loop Lists<\/li>\n\n\n\n<li>List Comprehension<\/li>\n\n\n\n<li>Sort Lists<\/li>\n\n\n\n<li>Copy Lists<\/li>\n\n\n\n<li>Join Lists<\/li>\n\n\n\n<li>List Methods<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Using_Python_Lists\"><\/span><strong>Using Python Lists<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Python lists offer a plethora of built-in functions that simplify data manipulation.
