Python如何获取当前所在目录

本文给大家讲解的是使用python获取当前所在目录的方法以及相关示例，非常的清晰简单，有需要的小伙伴可以参考下

#!/usr/bin/env python
import os
import sys

if __name__ == '__main__':
  print "sys.path[0] =", sys.path[0]
  print "sys.argv[0] =", sys.argv[0]
  print "__file__ =", __file__
  print "os.path.abspath(__file__) =", os.path.abspath(__file__)
  print "os.path.realpath(__file__) = ", os.path.realpath(__file__)
  print "os.path.dirname(os.path.realpath(__file__)) =", os.path.dirname(os.path.realpath(__file__))
  print "os.path.split(os.path.realpath(__file__)) =", os.path.split(os.path.realpath(__file__))
  print "os.getcwd() =", os.getcwd() 

$ python /e/pyws/path_demo.py
sys.path[0] = E:\pyws
sys.argv[0] = E:/pyws/path_demo.py
__file__ = E:/pyws/path_demo.py
os.path.abspath(__file__) = E:\pyws\path_demo.py
os.path.realpath(__file__) = E:\pyws\path_demo.py
os.path.dirname(os.path.realpath(__file__)) = E:\pyws
os.path.split(os.path.realpath(__file__)) = ('E:\\pyws', 'path_demo.py')
os.getcwd() = D:\ 

$ ./pyws/path_demo.py
sys.path[0] = E:\pyws
sys.argv[0] = ./pyws/path_demo.py
__file__ = ./pyws/path_demo.py
os.path.abspath(__file__) = E:\pyws\path_demo.py
os.path.realpath(__file__) = E:\pyws\path_demo.py
os.path.dirname(os.path.realpath(__file__)) = E:\pyws
os.path.split(os.path.realpath(__file__)) = ('E:\\pyws', 'path_demo.py')
os.getcwd() = E:\
