都在try cache后面使用

1. 普通方法

        import sys, os, traceback, base64
        errorMeg = ''
        for file, lineno, function, text in traceback.extract_tb(sys.exc_info()[2]):
            errorMeg += '%s\n%s, in %s\n%s:                %s!' % (str(e), file, function, lineno, text)
        print "*" * 150
        print errorMeg 

2.系统方法

    print "#"*50
    import sys
    kkk = 15
    f_back = sys._getframe()
    for i in range(kkk):
        f_back = getattr(f_back, "f_back",'end')
        if f_back=='end' or f_back is None:
            break
        #函数名,行数,文件名
        myfo = sys._getframe(i)
        print myfo.f_code.co_name, myfo.f_lineno,myfo.f_code.co_filename
