True Divide arguments element-wise in Numpy

NumpyServer Side ProgrammingProgramming

To true divide arguments element-wise, use the numpy.true_divide() method in Python Numpy. The arr1 is considered Dividend array. The arr2 is considered Divisor array.

The out is a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

The condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized.

Steps

At first, import the required library −

import numpy as np

Create two 2D arrays −

arr1 = np.array([[14, 28, 56], [84, 56, 112]])
arr2 = np.array([[7, 14, 21], [28, 35, 56]])

Display the arrays −

print("Array 1...\n", arr1)
print("\nArray 2...\n", arr2)

Get the type of the arrays −

print("\nOur Array 1 type...\n", arr1.dtype)
print("\nOur Array 2 type...\n", arr2.dtype)

Get the dimensions of the Arrays −

print("\nOur Array 1 Dimensions...\n",arr1.ndim)
print("\nOur Array 2 Dimensions...\n",arr2.ndim)

Get the shape of the Arrays −

print("\nOur Array 1 Shape...\n",arr1.shape)
print("\nOur Array 2 Shape...\n",arr2.shape)

To true divide arguments element-wise, use the numpy.true_divide() method in Python Numpy. The arr1 is considered Dividend array. The arr2 is considered Divisor array −

print("\nResult...\n",np.true_divide(arr1, arr2))

Example

import numpy as np

# Create two 2D arrays
arr1 = np.array([[14, 28, 56], [84, 56, 112]])
arr2 = np.array([[7, 14, 21], [28, 35, 56]])

# Display the arrays
print("Array 1...\n", arr1)
print("\nArray 2...\n", arr2)

# Get the type of the arrays
print("\nOur Array 1 type...\n", arr1.dtype)
print("\nOur Array 2 type...\n", arr2.dtype)

# Get the dimensions of the Arrays
print("\nOur Array 1 Dimensions...\n",arr1.ndim)
print("\nOur Array 2 Dimensions...\n",arr2.ndim)

# Get the shape of the Arrays
print("\nOur Array 1 Shape...\n",arr1.shape)
print("\nOur Array 2 Shape...\n",arr2.shape)

# To true divide arguments element-wise, use the numpy.true_divide() method in Python Numpy
# The arr1 is considered Dividend array
# The arr2 is considered Divisor array
print("\nResult...\n",np.true_divide(arr1, arr2))

Output
