Answer from pho on Stack OverflowIf a valid align value is specified, it can be preceded by a fill character that can be any character and defaults to a space if omitted. It is not possible to use a literal curly brace (“
{” or “}”) as the fill character in a formatted string literal or when using thestr.format()method. However, it is possible to insert a curly brace with a nested replacement field. This limitation doesn’t affect theformat()function

According to the Format Specification Mini-Language you have to specify it before the "align":
contents = [('Introduction', 1), ('Python Basics', 5),
('Creating Your First Program', 12),
('Operators and Variables', 29)]
row_length = 35
for chapt, page in contents:
dots = str(row_length - len(str(page)))
print(f"{chapt:.<{dots}}{page}")
*This is now independent of the page number's length. A little bit more flexible.

Maybe your computer is broken. >>> print(f"{'today':25}" + "xx") today xx >>> print(f"{'tomorrow':25}" + "xx") tomorrow xx >>> print(f"{'the day after tomorrow':25}" + "xx") the day after tomorrow xx Actually, looking at it a bit it's pretty clear that your browser is not using a monospace font.

In this statement print(f"|{students[i+j]:^{CELL_WIDTH}}", end='') the data type of variable CELL_WIDTH is float which is supposed to be int ..
Change the statement CELL_WIDTH = (LINE_WIDTH - STUDENTS_PER_ROW - 1) / STUDENTS_PER_ROW with CELL_WIDTH = (LINE_WIDTH - STUDENTS_PER_ROW - 1) // STUDENTS_PER_ROW which will make CELL_WIDTH datatype as int..

I think you'd need to add int() to your statement because CELL_WIDTH is a float value.
So:
CELL_WIDTH=int(LINE_WIDTH - STUDENTS_PER_ROW-1)/STUDENTS_PER_ROW
Hope that helps!
