sys.stdin.readlines()挂起Python脚本 [英] sys.stdin.readlines() hangs Python script

问题描述

每次执行Python脚本时，它似乎都挂在这行上:

Everytime I'm executing my Python script, it appears to hang on this line:

lines = sys.stdin.readlines()

我应该怎么做才能解决/避免这个问题?

What should I do to fix/avoid this?

编辑

这就是我在使用lines所做的事情:

Here's what I'm doing with lines:

lines = sys.stdin.readlines()
updates = [line.split() for line in lines]

我正在从git钩子运行此脚本，所以EOF周围仍然存在吗?

I'm running this script from a git hook so is there anyway around the EOF?

推荐答案

这在很大程度上取决于您要完成的工作.您也许可以:

This depends a lot on what you are trying to accomplish. You might be able do:

for line in sys.stdin:
    #do something with line

当然，对于这个惯用语以及您正在使用的readlines()方法，您都需要以某种方式将EOF字符发送到脚本中，以便它知道可以读取文件了. (在Unix上，Ctrl-D通常可以解决问题).

Of course, with this idiom as well as the readlines() method you are using, you need to somehow send the EOF character to your script so that it knows that the file is ready to read. (On unix Ctrl-D usually does the trick).
