Python是否有高级分析模块?

题
我想介绍我的Python代码。我很了解 cProfile
, ,我使用它,但是它太低了。 (例如,甚至没有一种直接的方法可以从要分析的函数中捕获返回值。)
我想做的一件事:我想在程序中扮演一个功能并将其设置为介绍 即时 运行程序时。
例如,假设我有一个功能 heavy_func
在我的程序中。我想启动该程序并拥有 heavy_func
功能本身不是概况。但是在我计划的运行时间里的某个时候,我想更改 heavy_func
在运行时概括自己。 (如果您想知道该程序运行时如何操纵内容:我可以从调试探测器或集成到GUI应用程序中的外壳中进行操作。)
是否已经编写了这样的模块?我可以自己写它,但我只是想问之前,所以我不会重新发明轮子。

我为此写了自己的模块。我叫它 cute_profile
. 这是代码. 这是测试.
这是 Garlicsim, ,因此,如果您想使用它,可以 安装 garlicsim
并做 from garlicsim.general_misc import cute_profile
.
如果要在Python 3代码上使用它,只需安装 Python 3叉 garlicsim
.
这是一个 过时 从代码中摘录:
import functools
from garlicsim.general_misc import decorator_tools
from . import base_profile
def profile_ready(condition=None, off_after=True, sort=2):
'''
Decorator for setting a function to be ready for profiling.
For example:
@profile_ready()
def f(x, y):
do_something_long_and_complicated()
The advantages of this over regular `cProfile` are:
1. It doesn't interfere with the function's return value.
2. You can set the function to be profiled *when* you want, on the fly.
How can you set the function to be profiled? There are a few ways:
You can set `f.profiling_on=True` for the function to be profiled on the
next call. It will only be profiled once, unless you set
`f.off_after=False`, and then it will be profiled every time until you set
`f.profiling_on=False`.
You can also set `f.condition`. You set it to a condition function taking
as arguments the decorated function and any arguments (positional and
keyword) that were given to the decorated function. If the condition
function returns `True`, profiling will be on for this function call,
`f.condition` will be reset to `None` afterwards, and profiling will be
turned off afterwards as well. (Unless, again, `f.off_after` is set to
`False`.)
`sort` is an `int` specifying which column the results will be sorted by.

)
return locals()['result']
