Python Exercises: Absolute difference between two consecutive digits

Python Math: Exercise-92 with Solution

Write a Python program that checks whether the absolute difference between two consecutive digits is two or not. Return true otherwise false.

Sample Data:
(666) -> False
(3579) -> True
(2468) -> True
(20420) -> False

Sample Solution-1:

Python Code:

def test(n):
    return all(abs(int(x) - int(y)) == 2 for x, y in zip(str(n), str(n)[1:]))
     
n = 666
print("Original number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))
n = 3579
print("\nOriginal number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))
n = 2468
print("\nOriginal number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))
n = 20420
print("\nOriginal number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))

Sample Output:

Original number: 666
Is absolute difference between two consecutive digits of the said number is 2 or not?
False

Original number: 3579
Is absolute difference between two consecutive digits of the said number is 2 or not?
True

Original number: 2468
Is absolute difference between two consecutive digits of the said number is 2 or not?
True

Original number: 20420
Is absolute difference between two consecutive digits of the said number is 2 or not?
False

Sample Solution-2:

Python Code:

def test(n):
    text = str(n)
    r = [int(x) for x in text]
    return all(abs(r[i]-r[i+1])==2 for i in range(len(r)-2))
     
n = 666
print("Original number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))
n = 3579
print("\nOriginal number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))
n = 2468
print("\nOriginal number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))
n = 20420
print("\nOriginal number:", n)
print("Is absolute difference between two consecutive digits of the said number is 2 or not?")
print(test(n))

Sample Output:

Original number: 666
Is absolute difference between two consecutive digits of the said number is 2 or not?
False

Original number: 3579
Is absolute difference between two consecutive digits of the said number is 2 or not?
True

Original number: 2468
Is absolute difference between two consecutive digits of the said number is 2 or not?
True

Original number: 20420
Is absolute difference between two consecutive digits of the said number is 2 or not?
False
