我如何操作一个名称与PDB命令冲突的变量?

My code is, for better or worse, rife with single letter variables (it's physics stuff, so those letters are meaningful), as well as NumPy's, which I'm often interacting with.

我的代码是，无论好坏，充斥着单个字母的变量(它是物理的东西，所以那些字母是有意义的)，以及NumPy的，我经常与之交互。

When using the Python debugger, occasionally I'll want to look at the value of, say, n. However, when I hit n<enter>, that's the PDB command for (n)ext, which has a higher priority. print n works around looking at it, but how can I set it?

当使用Python调试器时，我偶尔会想看看，比如说，n.但是，当我点击n ，那是PDB命令(n)ext，它有更高的优先级。打印n在周围看着它，但是我怎么设置它呢?

#1

Use an exclamation mark ! before a statement to have it run :

使用惊叹号!在语句之前运行:

python -m pdb test.py
> /home/user/test.py(1)<module>()
-> print('foo')
(Pdb) !n = 77
(Pdb) !n
77
(Pdb) n
foo
> /home/user/test.py(2)<module>()
-> print('bar')
(Pdb)

You can use semicolons, so just put something else in front of it:

你可以用分号，所以在它前面放点别的东西:

ipdb> print n
2
ipdb> n
> 145 <some code here>
  146
  147

ipdb> 1; n=4
1
ipdb> print n
4

That is not the direct answer to your question, but it may help you: PuDB is a console-based visual interface for PDB which separates commands from variable manipulation by design.

这并不是您问题的直接答案，但它可能会对您有所帮助:PuDB是一个基于conso的PDB可视化界面，它通过设计将命令和变量操作分离开来。

Eric IDE, Wing IDE & Spyder to mention just a few all have visual debuggers that are worth a go as they separate the display of values from the commands.

Eric IDE, Wing IDE & Spyder提到的只是少数几个都有可视调试器，当它们将值的显示从命令中分离出来时，这些调试器是值得一试的。
