Write a programExercise 4/4Intermediate30 XP

A number with spaces

Task

The program reads a non-negative whole number (without leading zeros) and prints it with the digits split from the end into groups of three by spaces: 1234567 → 1 234 567.

Solve it by working with the string (slices, a loop) - do not use the :, format or the format function.

Examples

  • Input

    1234567

    Expected output

    1 234 567

Rules

  • Build the groups with slices - without the :, format or format.

After you submit, 6 hidden tests will also check your solution: zero, exactly three digits, four digits, six digits, eleven digits, 1234.

Python starts the first time you run code.
