我编写了一个python脚本来备份我的文件，比如Dropbox。
但是有一些错误。我有一个名为SyncServer的课程，分别有两个名为__init__和TF1的函数。 TF1代表“线程函数1”。
当我写第一个参数thread.start_new_thread(TF1, (conn, 0))时，我发送了一个套接字对象。不幸的是，python的IDLE回复了一个错误：NameError: global name 'TF1' is not defined

答案 0 :(得分：4)
thread.start_new_thread(TF1, (conn, 0))
假设TF1是全球性的。
"NameError: global name 'TF1' is not defined"
说明TF1 不是全球性的。
一定是假设是错误的。
TF1是类中的方法函数。因此，它需要通过类名或对象实例进行限定。通常，self.TF1是合适的。
