Python's Add and Pop Methods in Lists, Dictionaries, and Sets

                                         

                                Python's Add and Pop Methods in Lists, Dictionaries, and Sets

• In Python, lists, dictionaries, and sets are versatile data structures that offer different methods for manipulation.
  
  
• Among these methods, add and pop stand out as fundamental operations for adding elements to and removing elements from these data structures.
  
  

1.Lists:

• lists are "mutable" - they can be changed. Using the standard indexing scheme.
  
  

        Add Method (append):

• The append() method adds an element to the end of the list.

        
       Pop Method (pop):

• The pop() method removes and returns the last element from the list. You can also specify an index to remove and return a specific element.

2.Dictionaries:

• Adding a key-value pair directly assigns a value to a key in the dictionary.

        Add Method (append):

    

  Pop Method (pop):

3.Set:

• A Set in Python programming is an unordered collection data type that is iterable, mutable and has no duplicate elements.

        Add Method (append):

        

        Pop Method (pop):

4.Tuple:

• In Python, tuples are immutable data structures, meaning once they are created, their contents cannot be changed.
  
  
• Therefore, tuples do not have methods like add or pop to modify their elements directly. However, you can achieve similar functionality through tuple concatenation and slicing.
