从Python

Question

在shell脚本中，我能够导出变量。我如何在Python中做同样的事情

Shell代码：

PYTHON_PATH=`which python`    
PYTHON_PATH=`dirname $PYTHON_PATH`    
PATH=/bin:/usr/bin    
export PATH=~/.local/bin:$PATH:$PYTHON_PATH

Python代码:(版本 - 2.7）

PYTHON_PATH = subprocess.check_output("which python", shell=True)    
PYTHON_PATH = os.path.dirname(PYTHON_PATH)    
PATH = os.path.expanduser('~') + "/.local/bin:" + PATH + ":" + PYTHON_PATH    
subprocess.call('export PATH="{}"'.format(PATH), shell=True)

这是在python中导出PATH变量的正确方法。

这是否回答了您的问题（来源：this question/answer）？

import subprocess
import os

PYTHON_PATH = subprocess.check_output("which python", shell=True)    
PYTHON_PATH = os.path.dirname(PYTHON_PATH)    

os.environ["PATH"] += os.pathsep + PYTHON_PATH.decode()
