I'm supposed to get a grid for the columns to be aligned:

   A B C D
10 . . . . 
 9 . . . .

and not like

   A B C D
10 . . . .
9 . . . .
A B C D E F G H I J K L M N O P Q R S
19 . . . . . . . . . . . . . . . . . . .
18 . . . . . . . . . . . . . . . . . . .
17 . . . . . . . . . . . . . . . . . . .
16 . . . . . . . . . . . . . . . . . . .
15 . . . . . . . . . . . . . . . . . . .
14 . . . . . . . . . . . . . . . . . . .
13 . . . . . . . . . . . . . . . . . . .
12 . . . . . . . . . . . . . . . . . . .
11 . . . . . . . . . . . . . . . . . . .
10 . . . . . . . . . . . . . . . . . . .
 9 . . . . . . . . . . . . . . . . . . .

 2 . . . . . . . . . . . . . . . . . . .
 1 . . . . . . . . . . . . . . . . . . .

however from my code the following output is given

CodePudding user response:

You can format your number to have a fixed width and pad it with spaces from right or left:

for i in reversed(range(20)):
    print(str(i).rjust(2))
...
12
11
10
 9
 8
 7
...

UPD: the whole code I'd rewrite:

from string import ascii_uppercase as letters

class Board():
    colour_name = {'E': '.', 'B': '@', 'W': 'O'}

    def __init__(self, size=9):
        self.size = size
        assert (self.size > 1 and self.size < 27), "Illegal board size: must be between 2 and 26."  # raising the assertation error if not within the ranges

    def __str__(self):
        column_names = letters[:self.size]
        row_numbers = reversed(range(1, self.size   1))
        empty_row = ' '.join([self.colour_name.get('E')] * self.size)

        print('   '   ' '.join(column_names))
        for i in row_numbers:
            print(str(i).rjust(2), empty_row)
        return str(Board)

    def get_size(self):
        return self.size

b = Board(19)
print(b)

CodePudding user response:

You can use either ljust or rjust to pad string with spaces (or other characters).

cols = list('ABCDEFGHIJKLMNOPQRS')
rows = list(range(90, 110))
firstColWidth = len(str(max(rows)))

# Header
print(' ' * firstColWidth, *cols)

# Table 
for row in rows:
    print(str(row).rjust(firstColWidth), *['.'] * len(cols))

Output:
