如何在Python中使用参数运行应用程序？ [英] How to run application with parameters in Python?

问题描述

我需要运行一个应用程序（二进制文件）并使用Python代码传递参数。一些参数表示在Python文件处理期间获得的字符串。

I need to run an application (binary file) and pass arguments using a Python code. Some arguments represent strings got during Python file processing.

for i in range ( len ( files ) ) :
    subprocess.call(["test.exe", files[i]]) //How to pass the argument files[i]

谢谢...

更新后的问题：

也许我不理解在Python 3中传递参数。没有参数的代码可以运行

Maybe I do not understand passing arguments in Python 3. A code without parameters runs OK

args = ['test. exe']
subprocess.call(args)

但是带有参数的代码会导致错误：

However the code with parameter causes an error:

args = ['test. exe']
subprocess.call(args, '-f')  //Error

错误：

Error File "C:\Python32\lib\subprocess.py", line 467, in call
return Popen(*popenargs, **kwargs).wait()
File "C:\Python32\lib\subprocess.py", line 652, in __init__
raise TypeError("bufsize must be an integer")
TypeError: bufsize must be an integer

推荐答案

args = ['test. exe']
subprocess.call(args, '-f')  //Error

应该是：

args = ['test.exe', '-f']
subprocess.call(args) 

命令行参数应该都在subprocess.call第一个参数的单个列表内。调用的第二个参数是bufsize，它应该是整数（因此，为什么会出现错误）

The command line argument should all be inside a single list for the first parameter of subprocess.call. The second argument to call is bufsize, which is supposed to be an integer (hence why you get the error you do)
