The previous value number generated by the generator serves as the seed value. When there is no previous value, it uses the current system time for the first time.<\/p>\n<p><strong>Syntax:<\/strong><\/p>\n<pre>random.seed(x, version)<\/pre>\n<p><strong>Parameters<\/strong><\/p>\n<p><strong>x:<\/strong> This is Optional. A seed value is required to generate a random number.<br \/>\nIf it is an integer, it is used directly; otherwise, it must be converted to an integer.<br \/>\nThe default value is None, and if None is specified, the generator will use the current system time.<\/p>\n<p><strong>version:<\/strong> An integer that specifies how to convert a parameter to an integer.<br \/>\nThe default value is 2.<\/p>\n<p><strong>Examples:<\/strong><\/p>\n<p><strong>Example1:<\/strong><\/p>\n<p><strong>Input:<\/strong><\/p>\n<pre>Given seed value = 12<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<pre
