Python列表只包含我创建的变量(Python List ONLY the variables I have created)

Python列表只包含我创建的变量(Python List ONLY the variables I have created)

我运行了我的Python脚本，根据%whos IPython命令创建了22变量。

我希望能够在Python（而不是IPython）脚本中列出我的变量。

到目前为止，我尝试了dir() ， vars().keys() ， locals().keys()和globals().keys() ：

In [2]: len( [v for v in dir() if not v.startswith('_')] ) Out[2]: 1015 In [3]: len( [v for v in vars().keys() if not v.startswith('_')] ) Out[3]: 1015 In [4]: len( [v for v in locals().keys() if not v.startswith('_')] ) Out[4]: 1015 In [5]: len( [v for v in globals().keys() if not v.startswith('_')] ) Out[5]: 1015

我只想要我创建的MY变量，我该怎么做？

I have run my Python script that created 22 variables according to %whos IPython command.

I want to be able to list MY variables from within a Python (not IPython) script.

So far, I tried dir(), vars().keys(), locals().keys() and globals().keys() :

In [2]: len( [v for v in dir() if not v.startswith('_')] ) Out[2]: 1015 In [3]: len( [v for v in vars().keys() if not v.startswith('_')] ) Out[3]: 1015 In [4]: len( [v for v in locals().keys() if not v.startswith('_')] ) Out[4]: 1015 In [5]: len( [v for v in globals().keys() if not v.startswith('_')] ) Out[5]: 1015

I ONLY want MY variables that I created, how can I do that ?

最满意答案

在声明之前，您可以跟踪原始的：

orig_keys = set(globals().keys()) a = 10 b = 100 c = 1000 my_keys = set(globals().keys()) - orig_keys print(my_keys)

结果是：

{'orig_keys', 'a', 'c', 'b'}

You can keep track of the original ones before declaring:

orig_keys = set(globals().keys()) a = 10 b = 100 c = 1000 my_keys = set(globals().keys()) - orig_keys print(my_keys)

Results in:

{'orig_keys', 'a', 'c', 'b'}
