从bash调用Python脚本与参数 [英] Call Python script from bash with argument

问题描述

我知道我可以使用以下命令从我的bash脚本运行一个python脚本：

  python python_script.py 
  

但是，如果我想从我的bash脚本传递一个变量/参数到我的python脚本呢？我该怎么做？

基本上bash会生成一个文件名，然后python会上传它，但是当我打电话给我时，我需要将文件名从bash发送到python

解决方案

要在bash脚本中执行python脚本，您需要调用与终端中相同的命令。例如

 > python python_script.py var1 var2 
  

要访问python中的这些变量，您需要

  import sys 
打印sys.argv [0]＃打印python_script.py 
打印sys.argv [1]＃prints var1 
 print sys.argv [2]＃prints var2 
  

I know that I can run a python script from my bash script using the following:

python python_script.py

But what about if I wanted to pass a variable / argument to my python script from my bash script. How can I do that?

Basically bash will work out a filename and then python will upload it, but I need to send the filename from bash to python when I call it.

解决方案

To execute a python script in a bash script you need to call the same command that you would within a terminal. For instance

> python python_script.py var1 var2

To access these variables within python you will need

import sys
print sys.argv[0] # prints python_script.py
print sys.argv[1] # prints var1
print sys.argv[2] # prints var2
