Attributeerror str object has no attribute

The Python "AttributeError: 'str' object has no attribute" occurs when we try to access an attribute that doesn't exist on string objects. To solve the error, make sure the value is of the expected type before accessing the attribute. If you print the value you are accessing the attribute on, it will be a string. To solve the error, track down where exactly you are setting the value to a string in your code and correct the assignment. A common cause of the error is trying to call the decode method on a string already decoded object. To solve the error, remove the call to the decode method because if you have a string, it is already decoded. We accessed the list element at index 2 , which is a string and called the append method on the string which caused the error. If you are writing to or reading from a file, make sure you aren't calling the write or read methods on the filename. The issue in the code sample is that we are calling the write method on a string the filename whereas we should be calling it on the file object. The in operator returns True if the substring is contained in the string and False otherwise. If you need to check if a string contains a substring in a case-insensitive manner, convert both strings to lowercase. If you need to check whether an object contains an attribute, use the hasattr function. The hasattr function takes the following 2 parameters:. The hasattr function returns True if the string is the name of one of the object's attributes, otherwise False is returned.
