如何：通過 Powershell 將參數傳遞給 Python 腳本

Question

我試圖通過 Powershell 將 2 個參數傳遞給 python 腳本。

代碼：

$env:PATHEXT += ";.py"

[Environment]::SetEnvironmentVariable("Path", "$env:Path;c:\Program Files\lcpython15\", "User") 

$args1 = "Test1"
$args2 = "Test2"
$Python_SetAttrib = "c:\ProgramData\set_cust_attr.py "

python $Python_SetAttrib $args1 $args2

USAGE FROM CMD.exe: 
c:\ProgramData\set_cust_attr.py <custom attribute name> <custom attribute value>

錯誤：

PS C:\ProgramData> python $Python_SetAttrib + $args1 +  $args2
usage: c:\ProgramData\set_cust_attr.sh <custom attribute name> <custom attribute value>
OR
usage: c:\ProgramData\Opsware\set_cust_attr.sh --valuefile <path to file with value     in     it> <custom attribute name>

python.exe : Got more than one custom attribute name.
At line:1 char:7
+ python <<<<  $Python_SetAttrib + $args1 +  $args2
    + CategoryInfo          : NotSpecified: (Got more than one custom attribute     name.:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

知道了！ 該死的單引號.....

$env:Path += ";c:\Program Files\lcpython15";
$env:PATHEXT += ";.py"; 
$arg1 = "Test3" 
$arg2 = "Testing" 
$arg3 = 'c:\ProgramData\set_cust_attr.py' 
python $arg3 $arg1 $arg2
