To return the real part of the complex argument, use the numpy.real() method. The method returns the real component of the complex argument. If val is real, the type of val is used for the output. If val has complex elements, the returned type is float. The 1st parameter, val is the input array. We will also change the real part of the complex argument using the array.real.
Steps
At first, import the required libraries-
import numpy as np
Create an array using the array() method −
arr = np.array([36.+1.j , 27.+2.j , 68.+3.j , 23.+2.j])
Display the array −
print("Our Array...\n",arr)
Check the Dimensions −
print("\nDimensions of our Array...\n",arr.ndim)
Get the Datatype −
print("\nDatatype of our Array object...\n",arr.dtype)
Get the Shape −
print("\nShape of our Array...\n",arr.shape)
To return the real part of the complex argument, use the numpy.real() method in Python. The method returns the real component of the complex argument. If val is real, the type of val is used for the output. If val has complex elements, the returned type is float.
The 1st parameter, val is the input array −
print("\nReal part...\n",np.real(arr))
Change the real part −
arr.real = 5 print("\nUpdated result...\n",arr)
Example
import numpy as np # Create an array using the array() method arr = np.array([36.+1.j , 27.+2.j , 68.+3.j , 23.+2.j]) # Display the array print("Our Array...\n",arr) # Check the Dimensions print("\nDimensions of our Array...\n",arr.ndim) # Get the Datatype print("\nDatatype of our Array object...\n",arr.dtype) # Get the Shape print("\nShape of our Array...\n",arr.shape) # To return the real part of the complex argument, use the numpy.real() method in Python print("\nReal part...\n",np.real(arr)) # Change the real part arr.real = 5 print("\nUpdated result...\n",arr)
Output
Our Array... [36.+1.j 27.+2.j 68.+3.j 23.+2.j] Dimensions of our Array... 1 Datatype of our Array object... complex128 Shape of our Array... (4,) Real part... [36. 27. 68. 23.] Updated result... [5.+1.j 5.+2.j 5.+3.j 5.+2.j]
