How to use the np.remainder() function for 2D array in Python
Maria ElijahOverview
The Python library NumPy has a method called remainder(). It is used to get the remainder of dividing two input arrays.
The numpy.remainder()method
The numpy.remainder() method returns the remainder by dividing two input arrays. This is done element-wise (element by element).
Note: A two-dimensional (2D) array can be created using a list of lists in Python.
Syntax
numpy.remainder(x1, x2, dtype=None, out=None)
Parameters
x1: Anarray_likethat represents a dividend array.x2: Anarray_likethat represents a divisor array.dtype: This is an optional parameter. It represents the return type of the array.out: This is an optional parameter. It represents the alternative output array in which the result is to be placed.
Note: If
x1andx2have distinct shapes, they must be broadcastable to a common shape for output representation.
Return value
The numpy.remainder() method returns the remainder of dividing two input arrays x1/x2.
Note: In Python, the
remainder()function is equivalent to the modulus operatorx1 % x2.
Code example
The following code shows how to use the numpy.remainder() method for two-dimensional (2D) arrays:
# import numpy import numpy as np # create a two 2D arrays x1 = np.array([[2,6,5],[3,4,8]]) x2 = np.array([[1,7,2],[10,9,4]]) # divide the 2D arrays # and store the remainder in result result = np.remainder(x1, x2) print(result)
Code explanation
- Line 2: We import the
numpylibrary. - Lines 4 and 5: We create two 2D arrays called
x1, andx2. - Line 9: We use the
np.remainder()method, which returns an array containing the remainder of dividing arrayx1by arrayx2. The result is stored in a new variable calledresult. - Line 11: We display the result.
