Data structure of symbol table

What is the data type of symbol table?
A symbol table is a data type that we use to associate values with keys.
Clients can store (put) an entry into the symbol table by specifying a key-value pair and then can retrieve (get) the value corresponding to a particular key from the symbol table..
Which data structure is used to symbol table?
There are three data structures used to implement symbol table: 1.
Linear list 2.
Binary tree 3.
Hash table 1..
A symbol table is a data structure maintained and constructed by the Python compiler that contains all of the essential information about each identifier found in the source code of the program.
This data pertains to an identifier's type, value, scope level, and its position (also called symbol).

In computer science, a symbol table is a data structure used by a language translator such as a compiler or interpreter, where each identifier (or symbol), constant, procedure and function in a program's source code is associated with information relating to its declaration or appearance in the source.

Symbol Table is an important data structure created and maintained by the compiler in order to keep track of semantics of variables i.e. it stores information about the scope and binding information about names, information about instances of various entities such as variable and function names, classes, objects, etc.
