Python报错：SyntaxError: unexpected EOF while parsing

报错
for receiver in receivers:
File "", line 1
for receiver in receivers:
^
SyntaxError: unexpected EOF while parsing

用readlines()读取出来的数据是一个列表，不需要用括号再括起来，用with open打开文件，不需要再用close()关闭。将recievers=...那行改写成：
with open(...) as f:
recievers=f.readlines()

你没有截全代码，看样子是for receiver in receivers:下面的print语句没有缩进
