# 使用real方法提取实部real_part=comp.real 1. 2. 在上面的代码中,我们调用了real方法,并将结果赋值给变量real_part。 完整代码示例 下面是完整的代码示例,演示了如何实现Python采用real方法提取实部: # 创建一个复数comp=complex(3,4)# 使用real方法提取实部real_part=comp.real# 打印实部print("实部:",real...
复数类型是 Python 的内置类型,直接书写即可。 复数由实部(real part)和虚部(imaginary part)构成,分别以一个浮点数表示。 在Python 中,复数的虚部以小写字母j或者大写字母J作为后缀(虚数单位),具体格式如下所示: a + bj 或 a + bJ 说明: a 表示实部; b 表示虚部。 实例如下所示: complex1 =22+12jprint...
In the second part of the tutorial, you saw more advanced decorators and learned how to: Decorate classes Nest decorators Add arguments to decorators Keep state within decorators Use classes as decorators You saw that, to define a decorator, you typically define a function returning a wrapper fun...

Since we are talking operators, there's also @ operator for matrix multiplication (don't worry, this time it's for real). >>> import numpy as np >>> np.array([2, 2, 2]) @ np.array([7, 8, 8]) 46 💡 Explanation: The @ operator was added in Python 3.5 keeping the scientif...
