问题：查找Python解释器的完整路径？

如何从当前执行的Python脚本中找到当前运行的Python解释器的完整路径？

How do I find the full path of the currently running Python interpreter from within the currently executing Python script?

sys.executable 包含当前运行的Python解释器的完整路径。

import sys

print(sys.executable)

现在记录在这里

sys.executable contains full path of the currently running Python interpreter.

import sys

print(sys.executable)

which is now documented here

只是使用os.environ以下方法来指出有用性的另一种方式：

import os
python_executable_path = os.environ['_']

例如

$ python -c "import os; print(os.environ['_'])"
/usr/bin/python

Just noting a different way of questionable usefulness, using os.environ:

import os
python_executable_path = os.environ['_']

e.g.

$ python -c "import os; print(os.environ['_'])"
/usr/bin/python

有几种其他方法可以找出Linux中当前使用的python：1）which python命令。2）command -v python命令3）type python命令

同样，在Windows上使用Cygwin也会得到相同的结果。

kuvivek@HOSTNAME ~
$ which python
/usr/bin/python

kuvivek@HOSTNAME ~
$ whereis python
python: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4        /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gz

kuvivek@HOSTNAME ~
$ which python3
/usr/bin/python3

kuvivek@HOSTNAME ~
$ command -v python
/usr/bin/python

kuvivek@HOSTNAME ~
$ type python
python is hashed (/usr/bin/python)

如果您已经在python shell中。尝试任何这些。注意：这是另一种方法。不是最好的pythonic方法。

>>>
>>> import os
>>> os.popen('which python').read()
'/usr/bin/python\n'
>>>
>>> os.popen('type python').read()
'python is /usr/bin/python\n'
>>>
>>> os.popen('command -v python').read()
'/usr/bin/python\n'

There are a few alternate ways to figure out the currently used python in Linux is: 1) which python command. 2) command -v python command 3) type python command

Similarly On Windows with Cygwin will also result the same.

kuvivek@HOSTNAME ~
$ which python
/usr/bin/python

kuvivek@HOSTNAME ~
$ whereis python
python: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4        /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gz

kuvivek@HOSTNAME ~
$ which python3
/usr/bin/python3

kuvivek@HOSTNAME ~
$ command -v python
/usr/bin/python

kuvivek@HOSTNAME ~
$ type python
python is hashed (/usr/bin/python)

If you are already in the python shell. Try anyone of these. Note: This is an alternate way. Not the best pythonic way.
