Python记录详细调用堆栈日志的方法

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()
