Python：哪些軟件包包含安裝元數據？

Question

例如，我怎樣才能知道可執行文件已經安裝在「/ usr/bin/python」以及「/usr/lib/python2.6」中的庫文件中？

Answer 1

distutils.sysconfig是，「提供訪問Python的低級別的配置信息」模塊。特別是，get_python_lib函數根據其參數給出「用於常規或平臺相關庫安裝的目錄」。

但是，sys.executable未被所述sysconfig模塊公開 - 它僅在sys模塊中。

Answer 2

你想要sys模塊：

>>> print sys.executable 
/usr/bin/python 
>>> print sys.path
