Windows가 셸에서 실행되는 Python 프로그램에 명령 줄 인수를 전달하지 않습니다.

Windows가 셸에서 실행되는 Python 프로그램에 명령 줄 인수를 전달하지 않습니다.

---

Windows 명령 셸에서 실행 가능한 명령으로 직접 실행하려고하면 명령 줄 인수를 Python 프로그램에 전달하는 데 문제가 있습니다. 예를 들어이 프로그램 (test.py)이있는 경우 :

import sys
print "Args: %r" % sys.argv[1:]

그리고 실행 :

>test foo
Args: []

비교하자면:

>python test.py foo
Args: ['foo']

내 구성은 다음과 같습니다.

PATH=...;C:\python25;...
PATHEXT=...;.PY;....

>assoc .py
.py=Python.File

>ftype | grep Python
Python.CompiledFile="C:\Python25\python.exe" "%1" %*
Python.File="C:\Python25\python.exe" "%1" %*
Python.NoConFile="C:\Python25\pythonw.exe" "%1" %*

---

나는 이것을 해결했다고 생각한다. 어떤 이유로 레지스트리에 SECOND 위치가 있습니다 (HKEY_CLASSES_ROOT \ Python.File \ shell \ open \ command에 저장된 파일 연결에 의해 표시되는 위치 외에) :

[HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command]
@="\"C:\\Python25\\python.exe\" \"%1\" %*"

이것은 내 시스템의 제어 설정 인 것 같습니다. 위의 레지스트리 설정은 "% *"를 추가하여 모든 인수를 python.exe에 전달합니다 (어떤 이유로 내 레지스트리에 누락되었습니다).

---

내 설정은 또 다른 레지스트리 키인 HKEY_CLASSES_ROOT\py_auto_file. 언급 된 다른 키도 존재했지만 Windows는 어떤 이유로이 키를 사용했습니다.

---

Windows 7의 Python 3.3의 경우 내 설정은 다른 레지스트리 키에있었습니다. 인수를 전달하기 위해 변경 한 핵심은

HKEY_USERS\S-1-5-21-3922133726-554333396-2662258059-1000_Classes\py_auto_file\shell\open\command

이었다 "C:\Python\Python33\python.exe" "%1". 나는 %*그것에 덧붙였다 . 이제 키 값은 "C:\Python\Python33\python.exe" "%1" %*입니다.

값 "C:\Python\Python33\python.exe" "%1"이 있는 다른 키가 여러 개 (적어도 5 개 이상) 있었지만이 키를 변경하여 작동했습니다.

---

나를 위해 작동하게하려면 레지스트리 경로를 사용해야했습니다.

HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

그리고 추가 %*

흥미 롭군. Python 2.6 및 Windows XP (5.1.2600)를 사용하여 여기에서 작동합니다.

C:\Documents and Settings\hbrown>python test.py foo
['test.py', 'foo']

C:\Documents and Settings\hbrown>test.py foo
['C:\\Documents and Settings\\hbrown\\test.py', 'foo']

C:\Documents and Settings\hbrown>test foo
['C:\\Documents and Settings\\hbrown\\test.py', 'foo']

C:\Documents and Settings\hbrown>type test.py
import sys
print sys.argv 

C:\Documents and Settings\hbrown>echo %PATHEXT%
.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PY 

C:\Documents and Settings\hbrown>assoc .py
.py=Python.File

Your program associations for .py files might be messed up. Just re-associate .py files with your python executable.

Right click a .py file > Open with > Choose default program ... > [find C:\PythonXY\python.exe]

I checked all registry keys with python.exe and py_auto_file and made them point to my current python installation including th %* at the end that passes arguments. They were quite a few:

• HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command:

  • org: "C:\miniconda3\python.exe" "%1" "%*"
  • changed: "C:\Python35\python.exe" "%1" "%*"

• HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

  • org: "C:\Program Files\Sublime Text 3\sublime_text.exe" "%1"
  • changed: "C:\Python35\python.exe" "%1" "%*"

• HKEY_CURRENT_USER\Software\Classes\py_auto_file\shell\open\command

  • org: "C:\Python35\python.exe" "%1" "%*"

• HKEY_USERS\S-1-5-21-2621213409-1291422344-4183577876-2165\Software\Classes\py_auto_file\shell\open\command

  • org: "C:\Python35\python.exe" "%1" "%*"

• HKEY_USERS\S-1-5-21-2621213409-1291422344-4183577876-2165_Classes\py_auto_file\shell\open\command

  • org: "C:\Python35\python.exe" "%1" "%*"

• HKEY_CLASSES_ROOT\Applications\pythonw.exe\shell\open\command

  • org: "C:\Python34\pythonw.exe" "%1"
  • changed: "C:\Python35\pythonw.exe" "%1" "%*"

• HKEY_CURRENT_USER\Software\Classes\Applications\python.exe\shell\open\command

  • org: "C:\Python35\python.exe" "%1" "%*"

But that didn't do the job for me. I had to change my default python application as well.

As one can see I have 3 Python versions installed. It is impossible to see which is which here so I tried all three of them as my default python application. Eventually I was able to get my script arguments with one of these three.

---

By looking through the Windows registry, I found all the places where anything like Python36\pythonw.exe "%1" %* appears.

When I type python app.py args at the command prompt, everything works properly.

When I use just the app name (app.py args) Windows opens app.py in Python, but the app fails when it tries to access argv[1], because len(argv) is 1.

Apparently Windows knows enough to pass a py file to Python, but I can't figure out from looking at registry entries how it constructs the command. It appears to be using "%1" rather than "%1" %*.

---

If fixed this on my Windows 10 system by editing the following registry keys:

Computer\HKEY_CLASSES_ROOT\py_auto_file\shell\open\command
Computer\HKEY_CLASSES_ROOT\Python.File\Shell\Open\Command
Computer\HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command

to this value:

"C:\Python27\python.exe" "%1" %*
