4.4 Symbol Tables. 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. A symbol table is a collection of key–value pairs.

Is there a program to build a symbol table?

Dictionary lookup. The most basic kind of symbol-table client builds a symbol table with successive put operations to support get requests. The program lookup.py builds a set of key-value pairs from a file of comma-separated values as specified on the command line and then writes values corresponding to the keys read from standard input.
