将目录作为命令行参数传递给python脚本 [英] Passing directory to python script as command line argument

问题描述

我试图传递一个特定的目录到一个python脚本，以后在脚本中使用该目录。目录可以位于任何地方。
例如，脚本应该在命令行上运行

I am trying to pass a particular directory to a python script and later use that directory in the script . the Directory can be located anywhere. for example, the script should run on the command line as

script.py directory_name

到目前为止，我看起来没什么。

So far I looked but nothing as such.

推荐答案

您可以这样做：

directory_name=sys.argv[n]

，如果用户未提供目录名称。

It is always good to catch the error, if directory name is not provided by the user.

import sys

...
...

try:
    directory_name=sys.argv[1]
    print(directory_name)
except:
    print('Please pass directory_name')
