zuizhong=[]
with open('score.txt','r') as f:
forlineinf.readlines():

line,line=line,line
zuizhong.append(line)
zuizhong.sort(reverse=True, key=lambda x: sum(]))

f.write(i+'\n' for i in zuizhong)
怎么运行不起{:10_254:} 第一个文件打开后关闭了吗 第二个文件以可读打开的你怎么写入文件呢 最后一行的写法也不对啊，i进行迭代了怎么写入到文件中呢 zuizhong=[]
with open('score.txt','r') as f:
forlineinf.readlines():
line=line.strip('\n')
line=line.split(',')
line,line=line,line
zuizhong.append(line)
zuizhong.sort(reverse=True, key=lambda x: sum(]))
with open('sorted.txt','w') as f:
for l in zuizhong:
for p in range(len(l)):
if p!=4:
f.write(l+',')
else:
f.write(l)
f.write('\n')
终于写好垃圾代码了
喏，代码给你，最佳给我{:5_108:}
