def question01(text): Implement this function that takes a string and checks that the three sets of braces "()<>{}" are all matched properly. # Any characters other than the 6 characters for braces should raise an Exception exception. # Any mismatched braces should raise an Exception exception. # If the string is fine, nothing need be done. # You must use rply's LexerGenerator and ParserGenerator to solve this problem.

Example test cases:

def test_test01(): arg1 = "" try: result = sol.question01(arg1) assert True except Exception: assert False arg1 = "." exc = False try: result = sol.question01(arg1) assert False except Exception: exc = True assert exc arg1 = "!" exc = False try: result = sol.question01(arg1) assert False except Exception: exc = True assert exc def test_test02(): arg1 = "()" try: result = sol.question01(arg1) assert True except Exception: assert False arg1 = "(())" try: result = sol.question01(arg1) assert True except Exception: assert False arg1 = "(" exc = False try: result = sol.question01(arg1) assert False except Exception: exc = True assert exc arg1 = "())" exc = False try: result = sol.question01(arg1) assert False except Exception: exc = True assert exc arg1 = "(()" exc = False try: result = sol.question01(arg1) assert False except Exception: exc = True assert exc
