import os,sys

if __name__=="__main__":
    print "__file__=%s" % __file__

    print "os.path.realpath(__file__)=%s" % os.path.realpath(__file__)

    print "os.path.dirname(os.path.realpath(__file__))=%s" % os.path.dirname(os.path.realpath(__file__))
　　
    print "os.path.split(os.path.realpath(__file__))=%s" % os.path.split(os.path.realpath(__file__))[0]　　

    print "os.path.abspath(__file__)=%s" % os.path.abspath(__file__)

    print "os.getcwd()=%s" % os.getcwd()

    print "sys.path[0]=%s" % sys.path[0]

    print "sys.argv[0]=%s" % sys.argv[0]

输出结果:
$ python ./python_test/test_path.py
__file__=./python_test/test_path.py
os.path.realpath(__file__)=./python_test\test_path.py
os.path.dirname(os.path.realpath(__file__))=./python_test
os.path.split(os.path.realpath(__file__))=./python_test
os.path.abspath(__file__)=./python_test\test_path.py
os.getcwd()=./
sys.path[0]=./python_test
sys.argv[0]=./python_test/test_path.py
