the below methods to create a dynamic variable name:<\/p>\n<ul>\n<li>Using globals() function<\/li>\n<li>Using locals() function<\/li>\n<li>Using exec() function<\/li>\n<li>Using vars() function<\/li>\n<\/ul>\n<p><strong>globals() function in python:<\/strong><\/p>\n<p>The globals() function in Python returns a dictionary that contains the current global symbol table.<\/p>\n<p>The globals() method retrieves the current global symbol table&#8217;s dictionary.<\/p>\n<p>A symbol table is a data structure maintained by a compiler that contains all relevant program information.<\/p>\n<p>Variable names, methods, classes, and so forth are examples of this.<\/p>\n<p>There are two types of symbol tables:<\/p>\n<ul>\n<li>Local symbol table<\/li>\n<li>Global symbol table<\/li>\n<\/ul>\n<p><strong>locals() function in python:<\/strong><\/p>\n<p>The local symbol table maintains all information relating to the program&#8217;s local scope and is accessed in Python
