Insert a python dict into an SQLite DB

由 若如初见. 提交于 2021-02-07 08:12:54
问题 I have a dictionary that I want to add all the values to an sqlite database. All the keys in the dictionary exist in the database, and all the keys are of type string. Yet, I am having trouble with getting the values into the database. The following code is ugly, insecure, and errors whenever it comes across a string with a " in it, but it sort of works. Query="INSERT INTO packages VALUES(" for tag in Tags: Query=Query + '"' + Package[tag] + '", ' Query=Query[:-2]+")" cursor.execute(Query)

Python dict.get('key') versus dict['key'] [duplicate]

由 半腔热情 提交于 2021-02-07 04:56:24
问题 This question already has answers here : Why dict.get(key) instead of dict[key]? (10 answers) Closed 4 years ago . Why does this throw a KeyError: d = dict() d['xyz'] But this does not? d = dict() d.get('xyz') I'm also curious if descriptors play a role here. 回答1: This is simply how the get() method is defined. From the Python docs: Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError. The
