What is AttributeError in Python ? Complete Overview

What is AttributeError in Python

AttributeError in python is caused by the scenario where we want to access any attribute from any python class which is no more a member ( method or variable ). Hey! now you will think I am not using OOPs on python and still, I am getting the same error. Let me tell you if you are not using a user-defined class in your code, it does not mean you are not using the python OOPs property. All the datatype str, int, etc. are nothing but classes in Python. Functions like len() etc their member function. Suppose we call any or invoke any function which is not a member of that class, The interpreter will throw the AttributeError in Python. Now let’s understand the scenarios and where AttributeError is too common.

AttributeError in python ( When does it occur ) ?

The attributeerror occurs mainly when because of two reasons.

Case 1: If the member attribute is out of scope in the latest release :

Suppose you wrote code where you used any python module. Now accidentally or knowingly you update the underline package. This time the same code which was running as expected earlier is throwing AttributeError. It is because in the current version ( latest version ) , any of the elements is out of scope. Now you have to downgrade the package to the previous version.

Apart from it, Sometimes we take the reference of any code piece from developer communities. Unfortunately, if the solution which we took as a reference is pointing to any old version and now in our environment, we are using the latest version. Here also we will the AttributeError.

For example – Attributeerror: dict object has no attribute has_key occurs in Python 3. x because it is deprecated syntax in Python 3. x. This has_key() is still supported in python 2. x.

8.Attributeerror: module time has no attribute clock ( Solved )

9.Attributeerror: module ‘pandas’ has no attribute ‘read_csv’ ( Solved )

10.AttributeError: ‘int’ object has no attribute ‘append’ ( Solved )

Case 2: If accessing attribute is referring wrong class –

Suppose you have created a dataframe and then run df.sort(), It will trough the error Attributeerror: dataframe’ object has no attribute ‘sort’  because dataframe object does not have sort() declared. Probably you can convert one particular column of  dataframe to a list and then call this sort() function.  Because this sort() function is defined in list type class/ object.
