使用with语句时,是否需要调用imap4类的closelogout方法?

docs不要提供太多上下文。

Changed in version 3.5: Support for the with statement was added.

在另一个,非with example , 他们调用这两种方法。

这样做吗?

with imaplib.IMAP4_SSL(IMAP) as imap:
# Do some stuff
...
imap.close()
imap.logout()

还是只是这个?

with imaplib.IMAP4_SSL(IMAP) as imap:
# Do some stuff
...

最佳答案

IMAP4.__exit__ 调用logout:

def __exit__(self, *args):  # from imaplib.py
try:
self.logout()
except OSError:
pass

所以你只需要调用 close(在 with block 之外):

with imaplib.IMAP4_SSL(IMAP) as imap:
# Do some stuff
imap.close()
