Python 二十行代码 实现2048小游戏，代码如下：
from random import choice def combline(ls): ls = [i for i in ls if i > 0] for i in range(len(ls)-1): if ls[i] == ls[i+1]: ls[i], ls[i+1] = ls[i]*2, 0 break else:return ls + [0] * (4 - len(ls)) return combline(ls) left = lambda matric:[combline(matric[i]) for i in range(4)] matric=[[0 for j in range(4)] for i in range(4)] directions = {'a': left,'d': lambda matric:[list(reversed(i)) for i in left([list(reversed(i)) for i in matric])],'w': lambda matric:[[left([[matric[j][i] for j in range(4)] for i in range(4)])[j][i] for j in range(4)] for i in range(4)],'s': lambda matric:[[[list(reversed(i)) for i in left([list(reversed(i)) for i in [[matric[j][i] for j in range(4)] for i in range(4)]])][j][i] for j in range(4)] for i in range(4)]} while True: i, j = choice([(i, j) for i in range(4) for j in range(4) if matric[i][j] == 0]) matric[i][j] = 2 for i in matric:print(*i, sep='\t') while True: direction = input('w, s, a, d: ').strip() # 上 w 下 s 左 a 右 d if direction in directions: if matric != directions[direction](matric): matric = directions[direction](matric) break好了，这B装得还可以吧，下面来还原详细的版本
from random import choice # combine row __________________________________________________________________________________________________________ def combline(ls): # remove zero ls = [i for i in ls if i > 0] # left combination for i in range(len(ls)-1): if ls[i] == ls[i+1]: ls[i] *= 2 ls[i+1] = 0 break else: # without combination return ls + [0] * (4 - len(ls)) # go on combining return combline(ls) # direction ____________________________________________________________________________________________________________ # left def left(matric): return [combline(matric[i]) for i in range(4)] # right def right(matric): reverse = [list(reversed(i)) for i in matric] reverse = left(reverse) reverse_2 = [list(reversed(i)) for i in reverse] return reverse_2 # up def up(matric): transpose = [[matric[j][i] for j in range(4)] for i in range(4)] transpose = left(transpose) transpose_2 = [[transpose[j][i] for j in range(4)] for i in range(4)] return transpose_2 # down def down(matric): reverse_transpose = [list(reversed(i)) for i in [[matric[j][i] for j in range(4)] for i in range(4)]] reverse_transpose = left(reverse_transpose) transpose_reverse = [[[list(reversed(i)) for i in reverse_transpose][j][i] for j in range(4)] for i in range(4)] return transpose_reverse # show _________________________________________________________________________________________________________________ def show_matric(matric): print('+-----+-----+-----+-----+') for i in matric: for j in i: if j == 2: print('|\033[35m%5d' % j, end='\033[0m') elif j >= 1024: print('|\033[31m%5d' % j, end='\033[0m') elif 2 < j < 1024: print('|\033[33m%5d' % j, end='\033[0m') else: print('|%5d' % j, end='') print('|') print('+-----+-----+-----+-----+') # judgment _____________________________________________________________________________________________________________ def defeat(matric): if [(i, j) for i in range(4) for j in range(4) if matric[i][j] == 0] == []: if matric == left(matric) == right(matric) == up(matric) == down(matric): score = sum([sum(i) for i in matric]) show_matric(matric) print('Your score \033[36;7m', score, '\033[0m game over', sep='') exit() # play _________________________________________________________________________________________________________________ def play(matric): directions = {'a': left, 'd': right, 'w': up, 's': down} while True: zero_list = [(i, j) for i in range(4) for j in range(4) if matric[i][j] == 0] i, j = choice(zero_list) matric[i][j] = 2 defeat(matric) show_matric(matric) while True: direction = input('w, s, a, d: ').strip() if direction in directions: if matric != directions[direction](matric): matric = directions[direction](matric) break # test _________________________________________________________________________________________________________________ # matric0 = [ # [16384, 8192, 2048, 512], # [512, 1024, 128, 256], # [16, 32, 64, 32], # [4, 16, 0, 0]] matric0 = [[0 for j in range(4)] for i in range(4)] play(matric0) 以上就是Python实现无图形界面2048游戏的代码，体现出Python代码精简的风格。
关于2048，核心代码有3部分
1、一维合并，例如：【2,0,2,4】→【8,0,0,0】
# combine row __________________________________________________________________________________________________________ def combline(ls): # remove zero ls = [i for i in ls if i > 0] # left combination for i in range(len(ls)-1): if ls[i] == ls[i+1]: ls[i] *= 2 ls[i+1] = 0 break else: # without combination return ls + [0] * (4 - len(ls)) # go on combining return combline(ls)2、矩阵转置以及还原，例如：
【2, 2, 4, 8】 ――> 【2, 0, 0, 0】 ――> 【2, 2, 4, 8】
【0, 4, 0, 0】 ――> 【2, 4, 4, 8】 ――> 【0, 4, 0, 0】
【0, 4, 0, 0】 ――> 【4, 0, 0, 0】 ――> 【0, 4, 0, 0】
【0, 8, 0, 0】 ――> 【8, 0, 0, 0】 ――> 【0, 8, 0, 0】
# matric & length & print ______________________________________________________________________________________________________ matric = [ [2, 2, 4, 8], [0, 4, 0, 0], [0, 4, 0, 0], [0, 8, 0, 0]] length = len(matric) def show_matric(matric): for i in matric: print(i) print() # transpose ---------------------------------------------------------- transpose = [[matric[j][i] for j in range(length)] for i in range(length)] show_matric(transpose) # restore restore = [[transpose[j][i] for j in range(length)] for i in range(length)] show_matric(restore)3、转置 ――> 合并 ――> 还原
例如：
【2, 2, 4, 8】 ――> 【2, 0, 0, 0】 ――> 【 2, 0, 0, 0】 ――> 【 2, 2, 4, 8】
【0, 4, 0, 0】 ――> 【2, 4, 4, 8】 ――> 【 2,16, 0, 0】 ――> 【 0,16, 0, 0】
【0, 4, 0, 0】 ――> 【4, 0, 0, 0】 ――> 【 4, 0, 0, 0】 ――> 【 0, 0, 0, 0】
【0, 8, 0, 0】 ――> 【8, 0, 0, 0】 ――> 【 8, 0, 0, 0】 ――> 【 0, 0, 0, 0】
# combine row __________________________________________________________________________________________________________ def combline(ls): # remove zero ls = [i for i in ls if i > 0] # left combination for i in range(len(ls)-1): if ls[i] == ls[i+1]: ls[i] *= 2 ls[i+1] = 0 break else: # without combination return ls + [0] * (4 - len(ls)) # go on combining return combline(ls) # direction _________________________________________________________________________________________________________________ # left def left(matric): return [combline(matric[i]) for i in range(4)] # up def up(matric): transpose = [[matric[j][i] for j in range(4)] for i in range(4)] # 转置 transpose = left(transpose) # 合并 restore = [[transpose[j][i] for j in range(4)] for i in range(4)] # 还原转置 return restore代码较为精简，当中压缩代码的技术主要有【列表推导式、lambda、字典】，点击【】中链接可查看相关知识。
