Python string 模块，splitfields() 实例源码
我们从Python开源项目中，提取了以下11个代码示例，用于说明如何使用string.splitfields()。
def sendportcmd(s, f, port):
hostname = gethostname()
hostaddr = gethostbyname(hostname)
hbytes = string.splitfields(hostaddr, '.')
pbytes = [repr(port//256), repr(port%256)]
bytes = hbytes + pbytes
cmd = 'PORT ' + string.joinfields(bytes, ',')
s.send(cmd + '\r\n')
code = getreply(f)
# Process an ftp reply and return the 3-digit reply code (as a string).
# The reply should be a line of text starting with a 3-digit number.
# If the 4th char is '-',it is a multi-line reply and is
# terminate by a line starting with the same 3-digit number.
# Any text while receiving the reply is echoed to the file.
