separate real and imaginary part of a complex number in python
提问by litepresence
I have need to extract the real and imaginary elements of a complex number in python. I know how to make a list into a complex number... but not the other way around.
我需要在python中提取复数的实部和虚部。我知道如何将列表变成一个复数……但反过来不行。
I have this:
我有这个：
Y = (-5.79829066331+4.55640490659j)
I need:
我需要：
Z = (-5.79829066331, 4.55640490659)
and I will also need each part if there is a way to go directly without going by way of Z:
如果有一种方法可以直接去而不通过Z，我也需要每个部分：
A = -5.79829066331
B = 4.55640490659

Z = (Y.real, Y.imag)
A = Y.real
B = Y.imag

import numpy as np #Can be done easily using Numpy Lib
array=np.array([3,4.5,3 + 5j,0]) #Initialize complex array
real=np.isreal(array) #Boolean condition for real part
real_array=array[real] #Storing it in variable using boolean indexing
imag=np.iscomplex(array) #Boolean condition for real part
imag_array=array[imag] #Storing it in variable using boolean indexing
print(real)
print(imag)
print(real_array)
print(imag_array)
