如何從python代碼設置PATH？

我試圖從python腳本設置ORACLE_HOME路徑如下，但它沒有工作，任何想法如何設置它？如何從python代碼設置PATH？

>>> subprocess.call(["export", "ORACLE_HOME="+ORACLE_HOME], env= os.environ) 
Traceback (most recent call last): 
    File "<stdin>", line 1, in ? 
    File "/usr/lib64/python2.4/subprocess.py", line 419, in call 
    return Popen(*args, **kwargs).wait() 
    File "/usr/lib64/python2.4/subprocess.py", line 550, in __init__ 
    errread, errwrite) 
    File "/usr/lib64/python2.4/subprocess.py", line 996, in _execute_child 
    raise child_exception 
OSError: [Errno 2] No such file or directory

使用os.environ：

os.environ['ORACLE_HOME'] = 'whatever'

偉大的..謝謝了很多。任何想法如何附加到現有的PATH？ – Shashi

@Shashi：'os.environ ['PATH'] + ='：whatever'' – cdarke
