Suppose I have a dictionary of the form:
the_board = {(1,1) : ' ', (1,2) : ' ', (1,3) : ' ',
(2,1) : ' ', (2,2) : ' ', (2,3) : ' ',
(3,1) : ' ', (3,2) : ' ', (3,3) : ' ',}
I want to print each row line by line. Currently I do something like this:
def display(board):
var = list(board.values()) # Iterator to print out the table
i = 0
j = 0
maxi = len(var)
while i < maxi:
while j < (i + 3):
print(var[j], end="")
if j < i+2:
print('|', end='')
j += 1
print()
if i < (maxi-1):
print("-+-+-")
i += 3
I am aware that this is most likely not the most "pythonic way" to achieve what I want. How would I do so in a more pythonic manner? (I am aware that I can use the keys to achieve this since I gave them coordinate keys, but I may need to print a tabular dictionary without ordered/subscripted keys, so I would appreciate a more general solution).
Found out about Python's range function, so now my code looks like this:
def display(board):
var = list(board.values()) # Iterator to print out the table
maxi = len(var)
for i in range(0, maxi, 3):
for j in range(i, (i+3)):
print(var[j], end="")
if j < i+2:
print('|', end='')
print()
if i < (maxi-1):
print("-+-+-")
Still not sure it's the best way to write it.
def chunks(l,n):
""" Split list into chunks of size n """
for i in range(0, len(l), n):
yield l[i:i+n]
def display(board):
for values in chunks(list(the_board.values()), 3):
print('|'.join(values)) # use str.join to concat strings with separators
print('-+-+-')
Hi If I understood you correctly this should be solution
board = {(1,1) : ' a ', (1,2) : ' b ', (1,3) : ' c ',
(2,1) : 'd ', (2,2) : 'e ', (2,3) : ' f ',
(3,1) : 'g ', (3,2) : ' h', (3,3) : ' i',}
print ( "Cordiantes --- Values")
for key , value in board.items():
print(key , " " , value)
Output Will Be
You can set the number of columns:
the_board = {
(1, 1): ' ', (1, 2): ' ', (1, 3): ' ',
(2, 1): ' ', (2, 2): ' ', (2, 3): ' ',
(3, 1): ' ', (3, 2): ' ', (3, 3): ' '
}
def display(board, ncols):
items = list(board.values())
separate_line = '\n' + '+'.join('-' * ncols) + '\n'
item_lines = []
i = 0
while i + ncols <= len(items):
item_line = '|'.join(items[i:i + ncols])
item_lines.append(item_line)
i += ncols
output = separate_line.join(item_lines)
print(output)
display(the_board, ncols=3)
