Python Exercises: Sum of the digits in each number in a list is equal

Python Basic - 1: Exercise-147 with Solution

A Python list contains three positive integers. Write a Python program to check whether the sum of the digits in each number is equal or not. Return true otherwise false.

Sample Data:

([13, 4, 22]) -> True
([-13, 4, 22]) -> False
([45, 63, 90]) -> True

Sample Solution-1:

Python Code:

def test(nums):
    return nums[0] % 9 == nums[1] % 9 == nums[2] % 9 

nums = [13, 4, 22]
print("Original list of numbers:", nums)
print("Check sum of the digits in each number of the said list is equal or not!")
print(test(nums))
nums = [-13, 4, 22]
print("Original list of numbers:", nums)
print("Check sum of the digits in each number of the said list is equal or not!")
print(test(nums))
nums = [45, 63, 90]
print("Original list of numbers:", nums)
print("Check sum of the digits in each number of the said list is equal or not!")
print(test(nums))

Sample Output:

Original list of numbers: [13, 4, 22]
Check sum of the digits in each number of the said list is equal or not!
True
Original list of numbers: [-13, 4, 22]
Check sum of the digits in each number of the said list is equal or not!
False
Original list of numbers: [45, 63, 90]
Check sum of the digits in each number of the said list is equal or not!
True

Sample Solution-2:

Python Code:

def test(nums):
    if nums[0] < 0 or nums[1] < 0 or nums[2] <0:
        return  False
    r = lambda x: sum(i for i in nums)
    x, y, z = nums
    return r(x) == r(y) == r(z)

nums = [13, 4, 22]
print("Original list of numbers:", nums)
print("Check sum of the digits in each number of the said list is equal or not!")
print(test(nums))
nums = [-13, 4, 22]
print("Original list of numbers:", nums)
print("Check sum of the digits in each number of the said list is equal or not!")
print(test(nums))
nums = [45, 63, 90]
print("Original list of numbers:", nums)
print("Check sum of the digits in each number of the said list is equal or not!")
print(test(nums))

Sample Output:

Original list of numbers: [13, 4, 22]
Check sum of the digits in each number of the said list is equal or not!
True
Original list of numbers: [-13, 4, 22]
Check sum of the digits in each number of the said list is equal or not!
False
Original list of numbers: [45, 63, 90]
Check sum of the digits in each number of the said list is equal or not!
True
