你可以使用 wrap 将字符串拆分为子字符串列表和 join 要合并创建的列表:

from textwrap import wrap

                                       # |                           |
def print_bitboard(board):             # v split for spaces          v split for newlines
    print('\n'.join([' '.join(wrap(line, 1)) for line in wrap(board, 8)]))

bitboard1 = '0000000000000000000000000000000000000000000000001111111100000000'
print_bitboard(bitboard1)

# 0 0 0 0 0 0 0 0

# 0 0 0 0 0 0 0 0

bitboard2 = '1000000010000000100000001000000010000000100000001000000010000000'
print_bitboard(bitboard2)
