Pandas is mainly used for data analysis and associated manipulation of tabular data in DataFrames. WebTo initialize your NumPy array with zeros, use the function np.zeros (shape) where shape is a tuple that defines the shape of your desired array. For example, np.zeros ( (3,)) defines a one-dimensional array with three “0” elements, i.e., [0 0 0]. And np.zeros ( (2,2)) is a two-dimensional array with two rows and two columns, i.e., [ [0 0] [0 0]].
