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 . . . . . . . . . . . . . . . . . . .
8 . . . . . . . . . . . . . . . . . . .
7 . . . . . . . . . . . . . . . . . . .
6 . . . . . . . . . . . . . . . . . . .
5 . . . . . . . . . . . . . . . . . . .
4 . . . . . . . . . . . . . . . . . . .
3 . . . . . . . . . . . . . . . . . . .
2 . . . . . . . . . . . . . . . . . . .
1 . . . . . . . . . . . . . . . . . . .
however from my code the following output is given
A B C D E F G H I J K L M N O P Q R S
19 . . . . . . . . . . . . . . . . . . .
18 . . . . . . . . . . . . . . . . . . .

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
# self.board=["empty"*self.size for x in range(size)]
def __str__(self):
from string import ascii_uppercase as letters # importing the alphabetical letters as uppercase
a_letters = list(letters[:self.size]) # getting the alphabetical letters based on the number of columns
num = iter(range(1, (self.size + 1))) # getting the numerical characters based on the number of rows
arr = [[self.colour_name.get('E') for i in range(self.size)] for i in range(self.size)] # creating an array of the empty spots
# arr = [['.' for i in range(self.size)] for i in range(self.size)] # creating an array of the empyty spots
print(' ' + ' '.join(a_letters)) # to adjust the space with the alphabetical letters with the rest of the grid
for i in arr: # using the loop to create the grid with the numerical characters
print(-(next(num) - (self.size + 1)), end=' ') # to make the numbers descend
print(' '.join(i))
return str(Board)
def get_size(self):#returns the size of the board
return self.size
#arr[int(move)[1])-1][a_letters.index(move[0])]=colour_name.get('E')
b = Board(19)
print(b)
print(b.get_size())
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)
