However one must know the differences between these ways because they can create complications in code that can be very difficult to trace out. Therefore I cannot use np.pad.For example, I want to pad a with zeros such that its shape matches b.The reason why I want to do this is so I can do: two_D_array = [] #Declaring an empty 1D list. Par exemple a[0, 1] donne ici 2. a.shape: renvoie les dimensions de l'array, d'abord le nombre de lignes, puis le nombre de colonnes, ici (2, 3).
