The cmath.phase() method returns the phase of a complex number.A complx number can be expressed in terms of its magnitude and angle. This angle is between vector (representing complex number) and positive x-axis
相位(Phase):可以使用cmath.phase()函数计算复数的相位,即复数向量和正实轴之间的角度。需要先import cmath模块。 import cmath a = 1 + 1j b = complex(3, 4) # 打印实部和虚部 print("实部:", b.real) print("虚部:", b.imag) # 复数运算 print("相加:", a + b) # 复数的模 print("a的...
The angle is commonly referred to as the phase or argument of a complex number. It’s useful to express the angle in radians rather than degrees when working with trigonometric functions.Here’s a depiction of a complex number in both coordinate systems:...

不可变数据(3 个):Number(数字)、String(字符串)、Tuple(元组); 可变数据(3 个):List(列表)、Dictionary(字典)、Set(集合) 1.4 Python 数字 数字数据类型用于存储数值。 他们是不可改变的数据类型,这意味着改变数字数据类型会分配一个新的对象。

In this tutorial, you learned about the versatility of Scikit-Learn, which simplifies the implementation of various machine learning algorithms. We have delved into examples of Regression, Classification, and Clustering. Despite being in the development phase and maintained by volunteers, Scikit-Learn ...
``` z1 = complex(2, 3) z2 = complex(4, 5) z3 = z1 * z2 print(z3) ``` 输出结果为:(-7+22j) 同样,我们可以使用“/”运算符计算两个复数的商。 除了基本的复数运算,Python 还支持复数的其他运算,例如求模、 求幅角和共轭。我们可以使用 abs() 函数求复数的模,使用 cmath.phase()函数...
, which offers interactive coding tutorials, says you can learn Python in as little as two months. But that assumes you can sit in front of a computer every day and practice from 8 a.m. to 5 p.m. If you have a day job, six months may be a more realistic timeline. That would re...
