我正在从一些开源网站编写这个2048程序。 然而，经过一段时间的比赛，“32”和“64”这样的数字就消失了！我似乎无法找到发生这种情况的原因，我已经将我的代码与源代码进行了比较。他们看起来一样:(
有谁知道这个问题？提前谢谢！
用于组合数字：
def combine(L):
global score
ans = [0,0,0,0]
num = []
for i in L:
if i != 0:
num.append(i)
length = len(num)
if length == 4:
if num[0] == num[1]:
ans[0] = num[0]+num[1]
score += ans[0]
if num[2] == num[3]:
ans[1] = num[2] + num[3]
score += ans[1]
else:
ans[1] = num[2]
ans[2] = num[3]
elif num[1] == num[2]:
ans[0] = ans[0]
ans[1] = num[1] + num[2]
ans[2] = num[3]
score += ans[1]
elif num[2] == num[3]:
ans[0] = num[0]
ans[1] = num[1]
ans[2] = num[2] + num[3]
score += ans[2]
else:
for i in range(length):
ans[i] = num[i]
elif length == 3:
if num[0] == num[1]:
ans[0] = num[0] + num[1]
ans[1] = num[2]
score += ans[0]
elif num[1] == num[2]:
ans[0] = num[0]
ans[1] = num[1] + num[2]
score += ans[1]
else:
for i in range(length):
ans[i] = num[i]
elif length == 2:
if num[0] == num[1]:

score += ans[0]
