Question

display LHS and RHS of a grammar separately

Answer 1

def display_grammar(grammar):
    print("LHS\t→ RHS")
    print("-----------------")
    for lhs, productions in grammar.items():
        for rhs in productions:
            print(f"{lhs}\t→ {rhs}")

# Example Grammar
# S → aA | bB
# A → a | ε
# B → b
grammar = {
    "S": ["aA", "bB"],
    "A": ["a", "ε"],
    "B": ["b"]
}
