  This program checks whether a number is a Special Number or not. A number is said to be a special number when the sum of the factorial of its digits is equal to the number itself. Example - 145 is a Special Number as 1!+4!+5!=145. Program- /*import java.util.*; public class SpecialNumberCheck {      public static void main(String args[])      {           Scanner ob=new Scanner(System.in);           System.out.println("Enter the number to be checked.");           int a=ob.nextInt();           int sum=0,b=a;           while(a!=0)//or a>0           {                int rem=a%10; int fact=1;                for(int i=1;i<=rem;i++)      ...

  Updating Dictionary You can update a dictionary by adding a new entry or a key-value pair, modifying an existing entry, or deleting an existing entry as shown below in the simple example − When the above code is executed, it produces the following result − dict['Age'] : 8 dict['School'] : DPS School Delete Dictionary Elements You can either remove individual dictionary elements or clear the entire contents of a dictionary. You can also delete the entire dictionary in a single operation.  To explicitly remove an entire dictionary, just use the del statement. Following is a  simple example − Accessing Values in Tuples To access values in a tuple, use the square brackets for slicing along with the index or indices to obtain the value available at that index. For example − When the above code is executed, it produces the following result − tup1[0] : physics tup2[1:5] : [2, 3, 4, 5] Updating Tuples Tuples are immutable which means you cannot update or change the values of ...

Python includes following list methods  1) list.append(obj) = Appends object obj to list  2) list.count(obj) = Returns count of how many times obj occurs in list  3) list.extend(seq) = Appends the contents of seq to list 4) list.index(obj) = Returns the lowest index in list that obj appears 5) list.insert(index, obj) = Inserts object obj into list at offset index 6) list.pop(obj=list[-1]) = Removes and returns last object or obj from list 7) list.remove(obj) = Removes object obj from list 8) list.reverse() = Reverses objects of list in place 9) list.sort([func]) = Sorts objects of list, use compare func if given Function with Description 1) cmp(tuple1, tuple2) = Compares elements of both tuples. 2) len(tuple) = Gives the total length of the tuple. 3) max(tuple) = Returns item from the tuple with max value. 4) min(tuple) = Returns item from the tuple with min value. 5) tuple(seq) = Converts a list into tuple. Built-in Dictionary Functions & Methods Python includes ...
