[Python]记录详细调用堆栈的日志

参考http://www.cnblogs.com/tuzkee/p/3243110.html

import sys
import os

def detailtrace(info):
    retStr = ""
    curindex=0
    f = sys._getframe()
    f = f.f_back        # first frame is detailtrace, ignore it
    while hasattr(f, "f_code"):
        co = f.f_code
        retStr = "%s(%s:%s)->"%(os.path.basename(co.co_filename),
                  co.co_name,
                  f.f_lineno) + retStr
        f = f.f_back
    print retStr+info

def foo():
    detailtrace("hello world")

def bar():
    foo()

def main():
    bar()

if __name__ == "__main__":
    main()

 输出：

aaa1.py(<module>:27)->aaa1.py(main:24)->aaa1.py(bar:21)->aaa1.py(foo:18)->hello world
