# 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.

# By default, ast.dump() prints the AST in a compact format. 
# However, there are two optional arguments that can enhance the readability:
# indent: Specifies the number of spaces to use for indentation. Setting it to a positive integer (e.g., 4) indents each level of the AST by that amount.
# annotate_fields: When set to True, adds field names as comments to the output, making it easier to identify each part of the AST.
