To read a file into a string, we need to make use of the io/ioutil package that Go's standard library provides us with.Inside the io/ioutil package, there's a function called ReadFile() which is used to open a file and then convert its contents into a slice of bytes, and if for some reason, it isn't able to do so, then it will return an error too.Here is the syntax of the ReadLine() function.func ReadFile(filename string) ([]byte, error)It should be noted that if the above function has made a successful call, then it will return err == nil, not err == ...

Suppose we want to read a JSON file in Go. By reading, we mean that we want to convert the file data into a struct in Go.Consider the JSON file shown below that we will use to read and then convert the data into the structure.{ "users": [ { "name": "Mukul Latiyan", "social": { "facebook": "https://facebook.com/immukul", "twitter": "https://twitter.com/immukul", "linkedin": "https://linkedin.com/immukul" } }, ...

To compute the bit-wise AND of a 1D and a 0D array element-wise, use the numpy.bitwise_and() method in Python Numpy. Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape. The where parameter is the condition 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 ... Read More
To return the data of a masked array as an ndarray, use the ma.getdata() method in Python Numpy. Returns the data of a (if any) as an ndarray if a is a MaskedArray, else return a as a ndarray or subclass if not.The subok parameter suggest whether to force the output to be a pure ndarray (False) or to return a subclass of ndarray if appropriate (True, default).A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans ... Read More
To return the mask of a masked array, use the ma.getmaskarray() method in Python Numpy. Returns the mask of arr as an ndarray if arr is a MaskedArray and the mask is not nomask, else return a full boolean array of False of the same shape as arr.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.StepsAt first, import the required ...

To compute the bit-wise AND of a 1D and a 2D array element-wise, use the numpy.bitwise_and() method in Python Numpy.Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape.The where parameter is the condition 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 ... Read More
To compute the bit-wise AND of two 1D arrays element-wise, use the numpy.bitwise_and() method in Python Numpy.

This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape.The where parameter is the condition 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 ... Read More

To determine whether input is an instance of masked array, use the ma.isMaskedArray() method in Python Numpy. This function returns True if x is an instance of MaskedArray and returns False otherwise. Any object is accepted as input.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.StepsAt first, import the required library −import numpy as np import numpy.ma as maCreating a ...

To determine whether input has masked values, use the ma.is_masked() method in Python Numpy. Accepts any object as input, but always returns False unless the input is a MaskedArray containing masked values. Returns True if the array is a MaskedArray with masked values, False otherwise.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.StepsAt first, import the required library −import numpy ...
