To get the dimensions of the Masked Array, use the ma.MaskedArray.ndim attribute in Python Numpy. 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 ...

To return a copy of an array with only the first character of each element capitalized, use the numpy.char.capitalize() method in Python Numpy. The arr is the input array of strings to capitalize. The function returns the output array of str or unicode, depending on input types.The numpy.char module provides ... Read More

To return element-wise string multiple concatenation, use the numpy.char.multiply() method in Python Numpy. The function multiply() returns the output array of string_ or unicode_, depending on input types.The numpy.char module provides a set of vectorized string operations for arrays of type numpy.str_ or numpy.bytes_.StepsAt first, import the required library −import ... Read More

To return element-wise string concatenation for two arrays of string, use the numpy.char.add() method in Python Numpy.The numpy.char module provides a set of vectorized string operations for arrays of type numpy.str_ or numpy.bytes_.The function add() returns the output array of string_ or unicode_, depending on input types of the same ...

To unpack elements of a uint8 array into a binary-valued output array, use the numpy.unpackbits() method in Python Numpy. The result is binary-valued (0 or 1). The axis is the dimension over which bit-unpacking is done. The axis is set using the "axis" parameter. To set the number of elements ... Read More

To unpack elements of a uint8 array into a binary-valued output array, use the numpy.unpackbits() method in Python Numpy. The result is binary-valued (0 or 1). The axis is the dimension over which bit-unpacking is done. The axis is set using the "axis" parameter. To set the number of elements ... Read More

To expand the shape of an array, use the numpy.expand_dims() method. Insert a new axis that will appear at the axis position in the expanded array shape. We will set axis 0 here. The function returns the View of the input array with the number of dimensions increased.NumPy offers comprehensive ... Read More

To shift the bits of integer array elements to the right, use the numpy.right_shift() method in Python Numpy. Bits are shifted to the right x2. Because the internal representation of numbers is in binary format, this operation is equivalent to dividing x1 by 2**x2.The x1 is the Input values. The ... Read More

To shift the bits of array elements of a 2D array to the left, use the numpy.left_shift() method in Python Numpy. Bits are shifted to the left by appending x2 0s at the right of x1. Since the internal representation of numbers is in binary format, this operation is equivalent ... Read More

To create a record array from a (flat) list of array, use the numpy.core.records.fromarrays() method in Python Numpy. The names is set using the "names" parameter. The field names, either specified as a comma-separated string in the form 'col1, col2, col3', or as a list or tuple of strings in ... Read More
