如何：通过Powershell将参数传递给Python脚本

我试图通过Powershell将2个参数传递给python脚本。如何：通过Powershell将参数传递给Python脚本

CODE：

$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>

错误：

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

从错误消息来看，问题似乎与您的Python代码，而不是您的PowerShell代码。 –

为什么在参数（'python $ Python_SetAttrib + $ args1 + $ args2'）之间使用'+'运算符？你想连接参数（如果是这样，你需要用parens包围它们，'（$ Python_SetAttrib + $ args1 + $ args2）'）？如果不是，我不知道你的意思。如果你的意思是让它们成为python脚本的独立参数，那么你完全不需要'+'。 – mojo

当我通过（）传递参数时，它给了我：“表达式或语句中的意外标记'args1'。” – user2542412

明白了！单引号.....

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