cProfile命令行如何减少输出 [英] cProfile command line how to reduce output

问题描述

我正在尝试在python脚本上运行cProfile，我关心的只是运行所花费的总时间。有没有办法修改

I'm trying to run cProfile on my python script and all I care about is the total time it took to run. Is there a way to modify

python -m cProfile myscript.py

所以输出只是总时间？

推荐答案

该答案假设您正在使用Unix终端。
我能想到的最快的方法是使用>运算符将结果重定向到文件中，然后用head读取文件，例如：

This answers supposes that you are using a Unix terminal. The fastest thing I can think of would be to redirect the results into a file with the ">" operator and then read the file with head, something like:

python -m cProfile your_python_file.py > temp_file && head -n 3 temp_file 

基本上，为了进一步解释我自己，您正在写所有剖析到temp_file（如果该文件不存在并且其名称并不重要，则将创建该文件）。然后，使用 head -n 3 显示该文件的前3行。当然，如果不需要，您将必须手动删除temp_file！希望这会有所帮助！

So basically, to explain my self further, you are writing all the results of the profiling into temp_file (this file will get created if it doesn't exist and its name does not really matter ). And after this you display the first 3 lines of this file with head -n 3 . Of course you will have to manually delete temp_file if you do not need it! Hope this helps!
