To compute the square root of input, use the scimath.sqrt() method in Python Numpy. The method returns the square root of x. If x was a scalar, so is out, otherwise an array is returned. The parameter x is the input value. For negative input elements, a complex value is returned
Steps
At first, import the required libraries −
import numpy as np
Creating a numpy array using the array() method −
arr = np.array([1, -4, -9, 16, -25, 36])
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 object...\n",arr.shape)
To compute the square root of input, use the scimath.sqrt() method in Python Numpy. The method returns the square root of x. If x was a scalar, so is out, otherwise an array is returned −
print("\nResult...\n",np.emath.sqrt(arr))
Example
import numpy as np # Creating a numpy array using the array() method arr = np.array([1, -4, -9, 16, -25, 36]) # 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 object...\n",arr.shape) # To compute the square root of input, use the scimath.sqrt() method in Python Numpy print("\nResult...\n",np.emath.sqrt(arr))
Output
Our Array... [ 1 -4 -9 16 -25 36] Dimensions of our Array... 1 Datatype of our Array object... int64 Shape of our Array object... (6,) Result... [1.+0.j 0.+2.j 0.+3.j 4.+0.j 0.+5.j 6.+0.j]
