**4. Write a small program that uses the AST module to open the lexer/parser example, and dumps the resulting AST. See if there are any arguments to the parse method which make the output easier to read.** **4.

Maybe we can first write a simple lexer sample, and then import `astor` module to output the AST in a more human-readable format. Maybe we can first write a simple lexer sample, and then import `astor` module to output the AST in a more human-readable format.
