PythonServer Side ProgrammingProgramming

When it is required to find all numbers in a range where there are perfect square, and sum of digits in the number is less than 10, list comprehension is used.

Below is the demonstration of the same −

## Example

Live Demo

lower_limit = int(input(“Enter the lower range: “))
upper_limit = int(input(“Enter the upper range: “))
my_list = []
my_list = [x for x in range(lower_limit,upper_limit+1) if (int(x**0.5))**2==x and
sum(list(map(int,str(x))))<10]
print(“The result is : “)
print(my_list)

## Output

Enter the lower range: 5
Enter the upper range: 12
The result is :
[9]

## Explanation

• The lower range and upper range are taken by the user.

• An empty list is defined.

• The list comprehension is used, to iterate over the lower and upper limits.

• The square root of the elements are found.

• The elements are summed up.

• It is converted to a list.

• This is assigned to a variable.

• The output is displayed on the console.
