Extracting the real and imaginary parts of an NumPy array of complex numbers
Numpy library gives us functions such as real()
and imag()
to find real and imaginary parts of a complex number.
real() :
To find real part of the complex numberimag() :
To find imaginary part of the complex number
Example 1 :
# importing the module import numpy as np # creating a NumPy array complex_num = np.array([ - 1 + 9j , 2 - 77j , 31 - 25j , 40 - 311j , 72 + 11j ]) # traversing the list for i in range ( len (complex_num)): print ( "{}. complex number is {}" . format (i + 1 , complex_num[i])) print ( "The real part is: {}" . format (complex_num[i].real)) print ( "The imaginary part is: {}\n" . format (complex_num[i].imag)) |

Output :
1. complex number is (-1+9j) The real part is: -1.0 The imaginary part is: 9.0 2. complex number is (2-77j) The real part is: 2.0 The imaginary part is: -77.0 3. complex number is (31-25j) The real part is: 31.0 The imaginary part is: -25.0 4. complex number is (40-311j) The real part is: 40.0 The imaginary part is: -311.0 5. complex number is (72+11j) The real part is: 72.0 The imaginary part is: 11.0
Example 2 : The imaginary value of real number will be 0.
# importing the module import numpy as np # creating a NumPy array complex_num = np.array([ - 1 , 31 , 0.5 ]) # traversing the list for i in range ( len (complex_num)): print ( "{}. Number is {}" . format (i + 1 , complex_num[i])) print ( "The real part is: {}" . format (complex_num[i].real)) print ( "The imaginary part is: {}\n" . format (complex_num[i].imag)) |

Output :
1. Number is -1.0 The real part is: -1.0 The imaginary part is: 0.0 2. Number is 31.0 The real part is: 31.0 The imaginary part is: 0.0 3. Number is 0.5 The real part is: 0.5 The imaginary part is: 0.0
