当我们需要 chmod +x file.py
我编写了一个 py 脚本来从网络获取页面，它只是足够的读写权限，所以我的问题是我们什么时候需要执行权限？
i wrote a py script to fetch page from web,it just read write permission enough,so my question is when we need execute permission?

如果您想通过输入 python file.py 来运行它，读/写就足够了。如果您想像编译程序一样直接运行它，例如
./file.py，那么您需要执行权限（以及顶部相应的 hash-bang 行）。Read/write is enough if you want to run it by typing
python file.py. If you want to run it directly as if it were a compiled program, e.g../file.py, then you need execute permission (and the appropriate hash-bang line at the top).如果您需要以这种方式运行脚本，则需要这样做：
./file.py。但请记住，您需要将 python 的路径放在脚本的最顶部：#!/usr/bin/python。但是等等，您需要确保拥有正确的路径，才能执行：
which python。It's required to do so if you need to run the script in this way:
./file.py. Keep in mind though, you need to put the path of python at the very top of the script:#!/usr/bin/python.But wait, you need to make sure you have the proper path, to do that execute:
which python.如果您希望能够直接使用
$ file.py运行它，那么您需要设置执行位。否则，您可以使用$ python file.py运行它。If you want to be able to run it directly with
$ file.pythen you'll need the execute bit set. Otherwise you can run it with$ python file.py.
