How to Delete Attributes and Objects in Python?

delattr function in Python

del operator in Python

QUIZ!

Following methods or functions can be used for deleting Python attributes and objects:

With the object's permission, the delattr() method is used to delete the named attribute from the object.
Syntax:
delattr(object, name)
There are just two parameters in this function:
<ul>
<li>
object:&nbsp; from which&nbsp; the name attribute is to be removed.
</li>
<li>
name:&nbsp; of the attribute&nbsp; which is to be removed.
</li>
</ul>
The function does not return a value; instead, it just removes the attribute if the object permits it.
Example:
<pre class="language-python"><code># Python code to illustrate delattr()

class WSC:

 stu1 = "Harshal"

 stu2 = "Zishan"

 stu3 = "Sumit"

 stu4 = "Amit"

 stu5 = "Shravan"

names = WSC()

print('Students before delattr()--')

print('First = ',names.stu1)

print('Second = ',names.stu2)

print('Third = ',names.stu3)

print('Fourth = ',names.stu4)

print('Fifth = ',names.stu5)

# implementing the method

delattr(WSC, 'stu5')

print('After deleting fifth student--')

print('First = ',names.stu1)

print('Second = ',names.stu2)

print('Third = ',names.stu3)

print('Fourth = ',names.stu4)

# this statement raises an error

print('Fifth = ',names.stu5)</code></pre>
Output:&nbsp;
<div>
<pre class="language-python"><code>Students before delattr()--
First = Harshal
Second = Zishan
Third = Sumit
Fourth = Amit
Fifth = Shravan
After deleting fifth student--
First = Harshal
Second = Zishan
Third = Sumit
Fourth = Amit</code></pre>
</div>

In Python, there is one more operator that performs the same function as the delattr() method. It's the del command.&nbsp;
Example:
<pre class="language-python"><code># Python code to illustrate del()

class WSC:

 stu1 = "Harshal"

 stu2 = "Zishan"

 stu3 = "Sumit"

 stu4 = "Amit"

 stu5 = "Shravan"

names = WSC()

print('Students before del--')

print('First = ',names.stu1)

print('Second = ',names.stu2)

print('Third = ',names.stu3)

print('Fourth = ',names.stu4)

print('Fifth = ',names.stu5)

# implementing the operator

del WSC.stu5

print('After deleting fifth student--')

print('First = ',names.stu1)

print('Second = ',names.stu2)

print('Third = ',names.stu3)

print('Fourth = ',names.stu4)

# this statement raises an error

print('Fifth = ',names.stu5)</code></pre>
Output:&nbsp;
<pre class="language-python"><code>Students before del--
First = Harshal
Second = Zishan
Third = Sumit
Fourth = Amit
Fifth = Shravan
After deleting fifth student--
First = Harshal
Second = Zishan
Third = Sumit
Fourth = Amit
The output is the same with an error: 
Traceback (most recent call last):
 File "/home/7c239eef9b897e964108c701f1f94c8a.py", line 26, in 
 print('Fifth = ',names.stu5)
AttributeError: 'WSC' object has no attribute 'stu5'</code></pre>

____ is a real-world entity that has its own identity and behavior.

Check whether the attribute exists or not

Checking whether the attribute exists or not

Runs normally, doesn’t display anything

Displays 0, which is the automatic default value

Error as one argument is required while creating the object

Error as display function requires additional argument

What will the outcome of the Python code below be?class test: def__innit__(self,a): self: a=a def display(self): print(self:a)obj=tet()obj.display()

Is the given Python code valid?&gt;&gt;&gt;class A: def__innit__(self,b): self: b=b def display(self): print(self:b)&gt;&gt;&gt;obj=A(‘Hello”)&gt;&gt;&gt;del.obj
