Python 中的标准数据类型有六种,分别是 number, string, list, tuple, set, dictionary,前文已经阐述过它们的对象类型都是继承了PyBaseObject_Type类型的PyType_Type类型的实例对象,本文则主要探究 Python 中 int 类型的实现。 不同于 C 和 C++ 中的int类型,Python 中的int类型最大的特点是它一般是不会溢出...
How come type affinity of malformed string that should be a integer, is actually a TEXT AND is accepted by SQLite? Why doesn't it throw error if it's clear that the string is not a number of any type? python:3.11.7,sqlalchemy:2.0.30,sqlite:3.45.1 ...
