Let's see how to do that using reshape (),. Read: **Python** NumPy zeros + Examples **Python** NumPy **2d** **array** initialize. Here we can see how to initialize a numpy 2-dimensional **array** by using **Python**. By using the np.empty() method we can easily create a numpy **array** without declaring the entries of a given shape and datatype. In **Python**, this method doesn't set the numpy **array** values to zeros. Step 1 We access the **2D array's** total element count—the Length property on a **2D** returns this value. Step 2 We copy the **2D array** elements into a 1D **array** . We loop over each dimension. Step 3 Here we return the 1D **array** . To access elements with 2 indexes, we will need to multiply the first index. Index multiplication. First, import the numpy module, import numpy as np. Now to change the shape of the numpy **array**, we will use the reshape () function of the numpy module, #Program:Reshape 1D **array**.
