# Take number
num = abs(int(input("Enter a number: ")))
# Check digit count
if num < 10:
print("Single-digit")
elif num < 100:
print("Double-digit")
else:
print("Multi-digit")Output
Enter a number: 5 Single-digit Enter a number: 45 Double-digit Enter a number: 123 Multi-digit
Use range checks to determine digit count.
Key Concepts:
- Single-digit: 0-9 (< 10)
- Double-digit: 10-99 (< 100)
- Multi-digit: 100+ (>= 100)
- Use abs() to handle negative numbers
