Python Coding Challange - Question With Answer(01180225)

 

Step-by-step Execution:

1. Define a Set:

   
   set1 = {10, 20, 30}

   • set1 is a set containing {10, 20, 30}.

2. Remove an Element:

   set2 = set1.remove(20)

   • The .remove(20) method removes the element 20 from set1.
   • However, remove() does not return anything; it modifies set1 in place.
   • This means set2 gets assigned the return value of set1.remove(20), which is None.

3. Print the Result:

   
   print(set2)

   • Since set2 = None, the output will be:

     
     None

---

Final Output:

None

Key Learning:

• .remove() modifies the original set but returns None.
• If you assign set2 = set1.remove(x), set2 will always be None.
