Text Formatting Text Formatting
Elementary+
English RU

You are given a long line (a monospace font), and you have to break the line in order to respect a given width. Then you have to format the text according to the given style: 'l' means you have to align the text to the left, 'c' for center, 'r' for right, and 'j' means you have to justify the text. Finally, the lines of the output shouldn’t end with a whitespace.

If you have to put 2 * n + 1 spaces around a line in order to center it, then put n spaces before, not n + 1.

The justification rules:

  • Since we can't always put the same number of spaces between words in a line, put big blocks of spaces first. For example: X---X---X--X--X--X when you have to put 12 spaces in 5 gaps: 3-3-2-2-2.
  • Don't justify the last line of a text.

You won't have to consider splitting a word into two parts because the given widths are big enough.

Input: A text (string), width (integer) and style (string).

Output: The formatted text (string).

Examples:

text = "Hi, my name is Alex and I am 18 years old."

text_formatting(text, 20, 'l') == \
"""Hi, my name is Alex
and I am 18 years
old."""

text_formatting(text, 20, 'c') == \
"""Hi, my name is Alex
 and I am 18 years
        old."""

text_formatting(text, 20, 'r') == \
""" Hi, my name is Alex
   and I am 18 years
                old."""

text_formatting(text, 20, 'j') == \
"""Hi,  my name is Alex
and  I  am  18 years
old."""

Preconditions:

  • all(len(word) <= width for word in text.split())
  • '\n' not in text
  • style in ('l', 'c', 'r', 'j')
  • 0 < len(text) <= 1000
