我开始学习 python,但遇到了 SyntaxError。当我构建过滤器以获取日志文件中的最新记录时。像这样的日志文件
Sat Jun 2 03:32:13 2012 [pid 12461] CONNECT: Client "66.249.68.236"

import time
lines=[]
f= open("/opt/CLiMB/Storage1/log/vsftp.log")
line = f.readline()
lines=[line for line in f]
def OnlyRecent(line):
return time.strptime(line.split("[")[0].strip(),"%a %b %d %H:%M:%S %Y" <(time.time()-(60*60*24*5)))
print ("\n".join(filter(OnlyRecent,lines)))
f.close()
运行时出错

如何解决它。谢谢!
