写道：

我很想做一些明显的事情琐碎如：

我有一个叫做tsys2list的交流程序当它被运行时，它要求用户给出tcal的值。这是一个变量。我想打电话给*" tsys2list"在pyrthon脚本中，我们称之为gamma.py。 &GT;&GT;&GT;但&LT;&LT;&LT;我想传递tcal的值。自动编程，而不是通过与键盘的交互。


我该怎么做？


谢谢我提前！

有很多方法可以做到这一点。我建议在子进程模块中检查

，看看它是否符合你的要求。或者你

可以学习一点Tkinter或wxPython并使用它来获得

用户的变量。或者您甚至可以通过命令行使用

raw_input进行操作。命令。

这只有在程序可以完全由

命令行参数控制时才有效。如果需要互动，OP可能会考虑使用pexpect

。

我没有看到*收集*输入（无论方法如何）如何解决

*传递*输入到子进程的问题。

为什么这么说？您可以使用子进程模块通过

stdin / stdout与程序进行交互。

如果需要交互，OP可能会考虑使用

pexpect。

Pexpect是一个不错的选择，但它只是在子流程提供的相同设施之上的一个自动化层。

Hi,

I am tryiong to do something obviously trivial such as:
I have a c program called "tsys2list" that when it is ran it asks the user to give the value of "tcal" which is a variable. I want to call the "tsys2list" from within a pyrthon script lets call it "gamma.py" >>>but<<< I want to pass the value of "tcal" to th eprogram automatically and not by interacting with the keyboard.

How do I do that?

thanks i advance!

There are probably many ways to do this. I would recommend checking
out the subprocess module and see if it does what you want. Or you
could learn a little Tkinter or wxPython and use that to get the
user''s variable. Or you could even do it via the command line using
the "raw_input" command.

This will only work if the program can be fully controlled by
commandline arguments. If interaction is required, the OP might consider
using pexpect.

I fail to see how *gathering* input (regardless of the method) solves
the problem of *passing* input to a subprocess.

Why do you say that? You can interact with programs via
stdin/stdout using the subprocess module.

If interaction is required, the OP might consider using
pexpect.

Pexpect is a good option, but it''s just an automation layer on
top of the same facilities that subprocess provides.
