# Python Program to Print all Disarium Numbers within Given range

In the previous article, we have discussed Python Program to Get Tangent value Using math.tan()
Disarium Number:

A Disarium number is one in which the sum of each digit raised to the power of its respective position equals the original number.

like 135 , 89, etc.

Here 1^1 + 3^2 + 5^3 = 135 so it is disarium Number

Examples:

Example1:

Input:

Given lower limit range = 7
Given upper limit range = 180

Output:

The disarium numbers in the given range 7 and 180 are:
7 8 9 89 135 175

Example 2:

Input:

Given lower limit range = 1
Given upper limit range = 250

Output:

The disarium numbers in the given range 1 and 250 are:
1 2 3 4 5 6 7 8 9 89 135 175

## Program to Print all Disarium Numbers within Given range

Below are the ways to Print all Disarium Numbers within the given range.

### Method #1: Using For Loop (Static input)

Approach:

• Give the lower limit range as static input and store it in a variable.
• Give the upper limit range as static input and store it in another variable.
• Loop from lower limit range to upper limit range using For loop.
• Inside the for loop take a variable say ‘num’ and initialize its value to the iterator value.
• Make a copy of the number so you can verify the outcome later.
• Make a result variable (with a value of 0) and an iterator ( set to the size of the number)
• Create a while loop to go digit by digit through the number.
• On each iteration, multiply the result by a digit raised to the power of the iterator value.
• On each traversal, increment the iterator.
• Compare the result value to a copy of the original number.
• Print if the given number is a disarium number.
• The Exit of the program.

Below is the implementation:

# Give the lower limit range as static input and store it in a variable.
lowlim_range = 7
# Give the upper limit range as static input and store it in another variable.
upplim_range = 180
print('The disarium numbers in the given range',
lowlim_range, 'and', upplim_range, 'are:')
# Loop from lower limit range to upper limit range using For loop.
for m in range(lowlim_range, upplim_range+1):

# given number
num = m
# intialize result to zero(ans)
ans = 0

# calculating the digits
digit_s = len(str(num))
# copy the number in another variable(duplicate)
dup_numbr = num
while (dup_numbr != 0):
# getting the last digit
remaindr = dup_numbr % 10
# multiply the result by a digit raised to the power of the iterator value.
ans = ans + remaindr**digit_s
digit_s = digit_s - 1
dup_numbr = dup_numbr//10
# It is disarium number if it is equal to original number
if(num == ans):
print(num, end=' ')


Output:

The disarium numbers in the given range 7 and 180 are:
7 8 9 89 135 175

### Method #2: Using For Loop (User input)

Approach:

• Give the lower limit range as user input using the int(input()) function and store it in a variable.
• Give the upper limit range as user input using the int(input()) function and store it in another variable.
• Loop from lower limit range to upper limit range using For loop.
• Inside the for loop take a variable say ‘num’ and initialize it’s value toÂ  iterator value .
• Make a copy of the number so you can verify the outcome later.
• Make a result variable (with a value of 0) and an iterator ( set to the size of the number)
• Create a while loop to go digit by digit through the number.
• On each iteration, multiply the result by a digit raised to the power of the iterator value.
• On each traversal, increment the iterator.
• Compare the result value to a copy of the original number.
• Print if the given number is a disarium number.
• The Exit of the program.

Below is the implementation:

# Give the lower limit range as user input using the int(input()) function and store it in a variable.
lowlim_range = int(input("Enter some Random number = "))
# Give the upper limit range as user input using the int(input()) function and store it in another variable.
upplim_range = int(input("Enter some Random number = "))
print('The disarium numbers in the given range',
lowlim_range, 'and', upplim_range, 'are:')
# Loop from lower limit range to upper limit range using For loop.
for m in range(lowlim_range, upplim_range+1):

# given number
num = m
# intialize result to zero(ans)
ans = 0

# calculating the digits
digit_s = len(str(num))
# copy the number in another variable(duplicate)
dup_numbr = num
while (dup_numbr != 0):
# getting the last digit
remaindr = dup_numbr % 10
# multiply the result by a digit raised to the power of the iterator value.
ans = ans + remaindr**digit_s
digit_s = digit_s - 1
dup_numbr = dup_numbr//10
# It is disarium number if it is equal to original number
if(num == ans):
print(num, end=' ')


Output:

Enter some Random number = 1
Enter some Random number = 250
The disarium numbers in the given range 1 and 250 are:
1 2 3 4 5 6 7 8 9 89 135 175
