Reshaping and Stacking NumPy ArraysReshaping and Stacking NumPy Arrays

Reshaping and stacking numPy arrays refers to changing the shape or size of an array or combining multiple arrays into a single array. NumPy provides several functions for reshaping and stacking arrays, such as:

  • reshape(): Reshapes an array to a new shape;
  • resize(): Resizes an array to a new shape, potentially adding or removing elements;
  • vstack(): Stacks arrays vertically (row-wise) to create a single array;
  • hstack(): Stacks arrays horizontally (column-wise) to create a single array;
  • concatenate(): Concatenates arrays along a given axis;
  • stack(): Stacks arrays along a new axis.

Task

  1. Create 3 numPy arrays;
  2. Reshape the array to a new shape;
  3. Resize the array to a new shape, potentially adding or removing elements;
  4. Stack the arrays vertically (row-wise) to create a single array;
  5. Stack the arrays horizontally (column-wise) to create a single array.
