An AttributeError is raised when an object does not have the specified attribute or method.
The error message “AttributeError: ‘list’ object has no attribute ‘apply'” suggests that you are trying to call the ‘apply’ method on a list object, but lists do not have an ‘apply’ method.
Here is an example to illustrate the error:
# Creating a list
my_list = [1, 2, 3, 4, 5]
# Trying to call 'apply' method on the list
my_list.apply() # This will raise an AttributeError
To fix this error, you need to make sure that you are calling the correct method on the appropriate object.
