本文介绍如何使用Python创建一个简单的命令行脚本，该脚本可以接收命令行参数并将其打印出来。通过示例代码展示如何读取第一个命令行参数并输出。

You'll now be able to create a Python script in the current folder.

Create a Python script that takes in a command line argument and prints it.
- Use output redirection or a command line editor to create a Python script called script.py in the home folder.
- Add code to the file that will read the first command line argument passed in and print it out

       /home/dq$ echo -e 'import sys\nif __name__=="__main__":\n    print(sys.argv[1])'
     

       >script.py                                                                      
     

       bash: script.py: Is a directory
