separate real and imaginary part of a complex number in python

问题

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.

I have this:

Y = (-5.79829066331+4.55640490659j)

I need:

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:

A = -5.79829066331
B = 4.55640490659

Thanks!

回答1:

Y = (-5.79829066331+4.55640490659j)

Z = (Y.real, Y.imag)

A = Y.real
B = Y.imag

回答2:

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)
