First, we will convert both lists to set to perform set difference operation. Then we will subtract the first set and second set and convert the returned set to a list again with the list() method. This list is assigned to the first list. Parallelly, we will subtract the second set ...
Say that you want to make sure that when you add or subtract two instances of this class, both operands have the same unit: Python storage.py class Storage(float): def __new__(cls, value, unit): instance = super().__new__(cls, value) instance.unit = unit return instance def _...
-= Subtracts the right operand from the left operand and stores the result in the left operand x -= y x = x - y *= Multiplies the right operand with the left operand and stores the result in the left operand x *= y x = x * y /= Divides the left operand by the right operand...
在英语口语中,我们通常会说 “Subtract 2 from 3”(从3中减去2)。 2.1.3 乘法运算符(*) 在Python3中,乘法运算符(*)用于返回两个数字的乘积,或者返回一个被重复的字符串。这是Python3和C/C++的一个主要区别,因为在C/C++中,乘法运算符只能用于数字。 例如: # 数字相乘 print(3 * 2) # 输出:6 # 字...

现在我们正在为add、subtract、multiply和divide做我们自己的数学函数。需要注意的重要一点是我们说的最后一行return a + b(在add中)。这样做的效果如下: 我们的函数被调用时带有两个参数:a和b。 我们打印出我们的函数正在做的事情,在这种情况下是“ADDING”。
