模(Magnitude):复数的模可以使用abs()函数计算,返回复数到原点的距离,即sqrt{a^2 + b^2}。 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)...
1. 2. 3. 4. 代码解释: cmath模块是Python标准库中的一个模块,用于进行复数运算。我们可以使用cmath模块中的complex()函数将实部和虚部组合成一个复数。 abs()函数用于计算复数的模长。 步骤3: 输出结果 最后,我们将计算得到的模长输出给用户。 print("Magnitude of the complex number:",magnitude) 1. 代...

m # Magnitude 0.0373464440537444 You use pint to create a quantity that has both a magnitude and a unit. By calling .to(), you convert to other units. For example, the example cylinder is about 141 cubic centimeters, which translates to approximately 8.63 cubic inches and 0.0373 gallons. ...
