• Symbol Class
• Symbols Class
• Operator Class

Symbol

class Symbol(symbol, name, *, param_count=0, after_loop=False, action=None)

Metadata wrapper for parser symbols.

Methods:

• as_operator()

• compare(other)

Symbols

class Symbols(symbols)

Collection wrapper around multiple Symbol objects.

Methods:

• at(index)

• contains_any(values)

• get(key, default=None)

• index(value, start=0, stop=None)

• items()

• iter(param_count=None, after_loop=True, during_loop=True)

• keys()

• values()

Operator

class Operator(operator)

Behavior-bearing symbol wrapper used during evaluation.

Methods:

• calculate(num1, num2)

• compare(num1, num2)

• union(*args)
