Question

关于line_profiler上的docs，我可以很好地分析我的代码，但是当我用python -m line_profiler script_to_profile.py.lprof查看输出时，我只看到27行代码。我希望看到大约250，因为这是我添加@profile装饰器的函数的长度。我的输出如下：

Timer unit: 1e-06 s

   192                                               files = os.listdir(datadir)
   193
   194                                               tabs = ['Contact', 'Costs_Contributions', 'Course', 'EducationalHistory', 'Events', 'FinancialAidScholarship',

   201         1            6      6.0      0.0

   203
   204                                               df = {}
   205                                               for tab in tabs:
   206         1            6      6.0      0.0          # match tab titles to files by matching first 5 non-underscore characters
   207        12          115      9.6      0.0          filename = filter(lambda x: tab.replace('_', '')[:5] in x.replace('_', '')[:5], files)[0]

它在for循环中间切断。

您可能在创建配置文件结果文件后修改了源文件，请尝试重新运行。因为打印的源代码line_profiler是从磁盘上的文件中读取的，参考：

https://github.com/rkern/line_profiler/blob/master/line_profiler.py#L190

line_profiler只显示少量行
