In regular Python, you can use the append()<\/code> method to add an item to the end of a list. You cannot use this method in NumPy. If you try to use the Python append()<\/code> method to add an item to the end of a NumPy array, you will see the AttributeError: \u2018numpy.ndarray\u2019 object has no attribute \u2018append\u2019<\/code> error.
<\/p>\n\n\n\n

This guide discusses in detail the cause of and the solution to this NumPy error. We will refer to an example to illustrate how to fix this error. Let\u2019s get started.<\/p>\n\n\n\n

AttributeError: \u2018numpy.ndarray\u2019 object has no attribute \u2018append\u2019<\/h2>\n\n\n\n

The AttributeError: \u2018numpy.ndarray\u2019 object has no attribute \u2018append\u2019<\/code> error is caused by using the append()<\/code> method to add an item to a NumPy array. You should instead use the numpy.append()<\/code> method if you want to add an item to a list.
<\/p>\n\n\n\n

The numpy.append()<\/code> method was specifically written for the NumPy library. NumPy arrays are different to regular Python arrays so it is reasonable that NumPy has its own method to add an item to an array.
<\/p>\n\n\n\n

The NumPy append()<\/code> method uses this syntax:
<\/p>\n\n\n\n

numpy.append(list_to_add_item, item_to_add)<\/pre><\/div>\n\n\n\n
The two parameters we will focus on are:
