Exercise 3.10: Silencing Errors

Exercise 3.10: Silencing Errors

Modify the parse_csv() function so that parsing error messages can be silenced if explicitly desired by the user. For example:

>>> portfolio = parse_csv('Data/missing.csv', types=[str,int,float], silence_errors=True)
>>> portfolio
[{'price': 32.2, 'name': 'AA', 'shares': 100}, {'price': 91.1, 'name': 'IBM', 'shares': 50}, {'price': 83.44, 'name': 'CAT', 'shares': 150}, {'price': 40.37, 'name': 'GE', 'shares': 95}, {'price': 65.1, 'name': 'MSFT', 'shares': 50}]
>>>

Error handling is one of the most difficult things to get right in most programs. As a general rule, you shouldn’t silently ignore errors. Instead, it’s better to report problems and to give the user an option to the silence the error message if they choose to do so.
