In Python, lists are written with square brackets. Some important points about Python Lists: The list can be homogeneous or heterogeneous.

    • Is NumPy a good library?

      NumPy supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, and sparse array libraries. The core of NumPy is well-optimized C code. Enjoy the flexibility of Python with the speed of compiled code.

    • How to remove specific elements in a NumPy array?

      Delete specific elements in 2D Numpy Array by its index position. When we don’t mention axis value, the default value is none which means the array gets flattened. After that, we use np.delete() to delete elements from rows and columns. The function will return a flattened array without the deleted rows and column elements.

      NumPy’s array class is called ndarray. It is also known by the alias array. Note that numpy.arrayis not the same as the Standard Python Library class array.array, which only handles one-dimensional arrays and offers less functionality. The more important attributes of an ndarrayobject are: ndarray.ndim the number of axes (dimensions) of the ...
