# Python Exercises: Absolute difference between two consecutive digits

## Python Math: Exercise-92 with Solution

Write a Python program to check 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

**Getting sorted iterable (can sort by "compare" function):**

>>> a = [1, 2, -3] >>> sorted(a) [-3, 1, 2] >>> sorted(a,key=abs) [1, 2, -3]
