Python Program to Check a number is Narcissistic Number or Not

Guys who are serious about learning the concepts of the java programming language should practice this list of programs in java and get a good grip on it for better results in exams or interviews.

Given a number, the task is to check whether the given number is a Narcissistic Number or Not in Python.

Narcissistic Number:

Narcissistic numbers are a type of number that can be generated by adding the sum of its own digits raised to the power of the number of digits.

Example:

370

Number of digits=3

3*(Number of digits)+7*(Number of digits)+0*(Number of digits)

3^(3)+7^(3)+0^3=370

So it is a Narcissistic Number.

Examples:

Example1:

Input:

Given Number =370

Output:

The given Number { 370 } is a Narcissistic Number

Example2:

Input:

Given Number =371

Output:

The given Number { 371 } is a Narcissistic Number

Program to Check a number is Narcissistic Number or Not in Python

Below are the ways to check whether the given number is a Narcissistic Number or Not in Python.

Using For loop(Static Input)
Using For loop(User Input)

Method #1: Using For Loop (Static Input)

Approach:

Give the number as static input and store it in a variable.
Convert this number into list of digits using list(),map(),int(),str() functions.
Store it in a variable.
Calculate the length of the list using the len() function and store it in a variable say listleng.
Take a variable tempo and initialize its value to 0.
Loop in this digits list using For loop.
Calculate the iterator value^listleng where ^ represents the power operator and store it in a variable.
Increment the tempo by the above variable.
After the end of For loop check if the tempo value is equal to the given number using the If conditional Statement.
If it is true then print the given number as a Narcissistic Number.
Else it is not a Narcissistic Number.
The Exit of the Program.

Below is the implementation:

# Give the number as static input and store it in a variable.
givennmb = 370
# Convert this number into list of digits using list(),map(),int(),str() functions.
# Store it in a variable.
numbedigis = list(map(int, str(givennmb)))
# Calculate the length of the list using the len() function
# and store it in a variable say listleng.
listleng = len(numbedigis)
# Take a variable tempo and initialize its value to 0.
tempo = 0
# Loop in this digits list using For loop.
for numbrdigit in numbedigis:
        # Calculate the iterator value^listleng where ^ represents
    # the power operator and store it in a variable.
    powevalu = numbrdigit**listleng
    # Increment the tempo by the above variable.
    tempo = tempo+powevalu
# After the end of For loop check if the tempo value is equal
# to the given number using the If conditional Statement.
if(tempo == givennmb):
        # If it is true then print the given number as a Narcissistic Number.
    print('The given Number {', givennmb, '} is a Narcissistic Number')
else:
        # Else it is not a Narcissistic Number.
    print('The given Number {', givennmb, '} is not a Narcissistic Number')

Output:

The given Number { 370 } is a Narcissistic Number

Method #2: Using For Loop (User Input)

Approach:

Give the number as user input using the int(input()) function and store it in a variable.
Convert this number into list of digits using list(),map(),int(),str() functions.
Store it in a variable.
Calculate the length of the list using the len() function and store it in a variable say listleng.
Take a variable tempo and initialize its value to 0.
Loop in this digits list using For loop.
Calculate the iterator value^listleng where ^ represents the power operator and store it in a variable.
Increment the tempo by the above variable.
After the end of For loop check if the tempo value is equal to the given number using the If conditional Statement.
If it is true then print the given number as a Narcissistic Number.
Else it is not a Narcissistic Number.
The Exit of the Program.

Below is the implementation:

# Give the number as user input using the int(input()) function and store it in a variable.
givennmb = int(input('Enter some random number = '))
# Convert this number into list of digits using list(),map(),int(),str() functions.
# Store it in a variable.
numbedigis = list(map(int, str(givennmb)))
# Calculate the length of the list using the len() function
# and store it in a variable say listleng.
listleng = len(numbedigis)
# Take a variable tempo and initialize its value to 0.
tempo = 0
# Loop in this digits list using For loop.
for numbrdigit in numbedigis:
        # Calculate the iterator value^listleng where ^ represents
    # the power operator and store it in a variable.
    powevalu = numbrdigit**listleng
    # Increment the tempo by the above variable.
    tempo = tempo+powevalu
# After the end of For loop check if the tempo value is equal
# to the given number using the If conditional Statement.
if(tempo == givennmb):
        # If it is true then print the given number as a Narcissistic Number.
    print('The given Number {', givennmb, '} is a Narcissistic Number')
else:
        # Else it is not a Narcissistic Number.
    print('The given Number {', givennmb, '} is not a Narcissistic Number')

Output:

Enter some random number = 371
The given Number { 371 } is a Narcissistic Number
