numpy.zeros_like¶ numpy.zeros_like(a, dtype=None, order='K', subok=True)¶ Return an array of zeros with the same shape and type as a given array. Also, these codes won’t run on online-ID. The numpy.zeros_like() method consists of four parameters, which are as follows: arrray : This parameter represents an array_like input subok :It true is invoked then it represents newly created array will be sub-class of array else it represents a base-class array order :The order parameter can be either C_contiguous or F_contiguous. If True, then the newly created array will use the sub-class type of ‘a’, otherwise it will be a base-class array. Pylint gives a false-positive error while using numpy.zeros_like ().
