# Take 3-digit number
num = int(input("Enter a 3-digit number: "))
# Extract digits
digit1 = num // 100
digit2 = (num // 10) % 10
digit3 = num % 10
# Check if all distinct
if digit1 != digit2 and digit2 != digit3 and digit1 != digit3:
print("All digits are distinct")
else:
print("Digits are not all distinct")Output
Enter a 3-digit number: 123 All digits are distinct Enter a 3-digit number: 122 Digits are not all distinct
Extract digits and compare them.
Key Concepts:
- Extract hundreds, tens, and units digits
- Compare all pairs: digit1 != digit2, digit2 != digit3, digit1 != digit3
- All must be different for distinct digits
