Try print vsftpd.read() instead and you''ll see the content of the file. regardsSteve--Steve Holden [phone] [phone]Holden Web LLC www.holdenweb.comPyCon TX 2006 www.python.org/pycon/ "Johhny" <ex*****@hotmail.com> writes: ===SNIP=== import stringWhy''s that here?

You did nothing with what you read, just with the object itself.--Jorge Godoy <go***@ieee.org> 这篇关于阅读文件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
