Python获取脚本路径（三种方式）

|---bin
|---test01.py
|---src
|---aaa.py
|---testcase
|---group01
|---pathtest.py

pathtest.py:

import os
import sys
import inspect

inspect.getfile(inspect.currentframe())和inspect.stack()[0][1]得到的是定义该函数的脚本文件的路径，包含脚本名称

inspect.stack()[1][1]得到的是调用该脚本的脚本文件的路径，包含脚本名称

#return the script path where the function is defined
def test():
this_file=inspect.getfile(inspect.currentframe())
path=os.path.abspath(os.path.dirname(this_file))
return path

#return the script path where the function is called
def script_path():
caller_file=inspect.stack()[1][1]
return os.path.abspath(os.path.dirname(caller_file))

#return the script path where the Python interpreter is started
def test02():
path=os.path.realpath(sys.argv[0])
if os.path.isfile(path):
path=os.path.dirname(path)
return os.path.abspath(path)

def current_path():
path=os.path.realpath(sys.path[0])
if os.path.isfile(path):
path=os.path.dirname(path)
return os.path.abspath(path)
else:
caller_file=inspect.stack()[1][1]
return os.path.abspath(os.path.dirname(caller_file))

aaa.py:

import sys
import os
import inspect
sys.path.append("..\\testcase\\group01")
import pathtest

#path="aaa"
#print pathtest.test()

def caller_func():
caller_path=pathtest.script_path()
return caller_path

def def_func():
def_path=pathtest.test()
return def_path

def real_func():
real_func=pathtest.test02()
return real_func

def curr_func():
cur_func=pathtest.current_path()
return cur_func

print caller_func()
print def_func()
print real_func()
print "+++++++++++++++++++++++++++++++++++++++++++++++++++++++++"

test01.py:

import sys
import os
import inspect
sys.path.append("..\\src")
import aaa

def func_a():
return aaa.caller_func()

def func_b():
return aaa.def_func()

def func_c():
return aaa.real_func()

def func_d():
return aaa.curr_func()

print func_a()
print func_b()
print func_c()
print func_d()

Python获取路径的三种情况：获取函数定义所在脚本路径，获取调用函数脚本所在路径，获取启动Python解释器脚本所在路径
最常用的方式就是pathtest.py中current_path中获取路径的方式。
