In different branches of physics, we frequently deal with vector del operator ($\\vec{abla}$). This del operator is generally used to find curl or divergence of a vector function or gradient of a scalar function. In many important cases, we need to know the parent vector whose curl or...
Python通过重写一些内置方法,实现了运算符的重载功能。 operator模块提供以下的特殊方法,可以将类的实例使用下面的操作符来操作 运算符重载示例: class Person: def __init__(self,name,age=18): self.name = name self.age = age # #加减运算符 def __sub__(self, other): return self.age - other.age...

其他区别就是basic_string的函数更多比如substr之类的,更别说operator+=以及basic_string_view了。
