The keys are unique identifiers for the values, and the values can be any type of data. Dictionaries are often used to store data in a way that is easy to access and search.<\/p>\n<p>Here is an example of a dictionary:<\/p>\n<p><code>{<br \/>\n  \"name\": \"John Doe\",<br \/>\n  \"age\": 30,<br \/>\n  \"address\": \"123 Main Street, Anytown, CA 91234\"<br \/>\n}<\/code><\/p>\n<p>In this example, the keys are &#8220;name&#8221;, &#8220;age&#8221;, and &#8220;address&#8221;. The values are &#8220;John Doe&#8221;, 30, and &#8220;123 Main Street, Anytown, CA 91234&#8221;.<\/p>\n<p>Dictionaries can be created using the <code>{}<\/code> syntax. For example, the <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> following code creates <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> a dictionary with two keys and two values:<\/p>\n<p><code>my_dictionary = {\"name\": \"John Doe\", \"age\": 30}<\/code><\/p>\n<p>Dictionaries can be accessed using the <code>[]<\/code> syntax.
