Python delattr() built-in function
From the Python 3 documentation
This is a relative of `setattr()`. The arguments are an object and a string. The string must be the name of one of the object’s attributes. The function deletes the named attribute, provided the object allows it. For example, `delattr(x, 'foobar')` is equivalent to `del x.foobar`.
Introduction
The delattr() function in Python is used to delete an attribute from an object. It’s the counterpart to setattr() and getattr().
Syntax
delattr(object, name)
- object: The object from which the attribute should be deleted.
- name: The name of the attribute to delete, given as a string.
Examples
Deleting an attribute from an object
class Person:
name = "John"
age = 30
person = Person()
print(person.__dict__) # Output: {'name': 'John', 'age': 30}
delattr(person, "age")
print(person.__dict__) # Output: {'name': 'John'}
Deleting a non-existent attribute
class Person:
name = "John"
person = Person()
try:
delattr(person, "age")
except AttributeError as e:
print(f"Error: {e}")
