Read this article to learn more about Python  Identity Operator.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-python-identity-operator\">What is Python Identity Operator<\/h2>\n\n\n\n<p><a href=\"https:\/\/www.skillvertex.com\/blog\/python-literals\/\" data-type=\"post\" data-id=\"6953\">Python <\/a>operator consists of two <a href=\"https:\/\/www.skillvertex.com\/blog\/python-operators\/\" data-type=\"post\" data-id=\"6937\">operators <\/a>such as &#8216;<strong>is<\/strong>&#8216;and &#8216;<strong>is not<\/strong>&#8216;. Both the values will be returned with the<a href=\"https:\/\/www.skillvertex.com\/blog\/python-booleans\/\" data-type=\"post\" data-id=\"7030\"> Boolean values<\/a>. The in-operators will check if the value comes true only if the operand object shares the same memory location.<\/p>\n\n\n\n<p>Furthermore, the memory location of the object will be achieved with the help of the &#8221;<strong>id()<\/strong>&#8221; function. Whereas, if both the<a href=\"https:\/\/www.skillvertex.com\/blog\/python-variables\/\" data-type=\"post\" data-id=\"6932\"> variables<\/a> id() are the same, then the in operator will return with the True.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># Identity Operator - 'is'\nx = &#91;1, 2, 3]\ny = &#91;1, 2, 3]\nz = x\n\n# 'is' operator checks if both variables refer to the same object in memory\nprint(x is y)  # False, because x and y refer to different objects\nprint(x is z)  # True, because x and z refer to the same object\n\n# Identity Operator - 'is not'\nprint(x is not y)  # True, because x and y do not refer to the same object\nprint(x is not z)  # False, because x and z refer to the same object<\/code><\/pre>\n\n\n\n<p>Output<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>False\nTrue\nTrue\nFalse<\/code><\/pre>\n\n\n\n<p>However, list and tuple will do<a href=\"https:\/\/www.skillvertex.com\/blog\/python-operators\/\" data-type=\"post\" data-id=\"6937\"> operations<\/a> very differently. The example given below contains two lists such as  &#8221;a&#8221; and &#8221;b&#8221;  with the same items and the id() varies.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>a=&#91;1,2,3]\nb=&#91;1,2,3]\nprint (\"id(a), id(b):\", id(a), id(b))\nprint (\"a is b:\", a is b)\nprint (\"b is not a:\", b is not a)<\/code><\/pre>\n\n\n\n<p> Output<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>id(a), id(b): 1552612704640 1552567805568\na is b: False\nb is not a: True<\/code><\/pre>\n\n\n\n<p>The list or tuple has memory locations of individual items only and not the items themselves. Thus,  &#8221;a &#8221; consists of an address of  10,20, or 30 integer objects that are located in a particular location and will be different from the of  &#8221;b&#8221;.<\/p>\n\n\n\n<p> Output<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>140734682034984 140734682035016 140734682035048\n140734682034984 140734682035016 140734682035048<\/code><\/pre>\n\n\n\n<p>Here, the &#8216;is&#8217; operator will return with a false value even if it contains the same numbers. This happens due to the two different locations of a  and b.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">Conclusion<\/h2>\n\n\n\n<p>To conclude, this article will improve our knowledge of the Python Identity Operator.
