Returning A Value from Python to PowerShell

Due to the use of dynamic the type must be cast to the expected type so you need to specify the -ReturnType parameter to do so.

Use-Python {

Invoke-Python "'Hello'" -ReturnType ([String])

}

Imports the numpy Python module and does some math

Access methods of modules directly!

Use-Python {

$np = Import-PythonModule "numpy"

[float]$np.cos($np.pi * 2)

[float]$np.sin(5)

[float]($np.cos(5) + $np.sin(5))

} -Version v3.7

Output

Using Scopes

You can use Python scopes to string together multiple Invoke-Python calls or to pass in variables from PowerShell.

Use-Python {

Use-PythonScope {

Invoke-Python -Code "import sys"

Invoke-Python -Code "sys.version" -ReturnType ([string])

}

}

Passing a .NET Object to Python

class Person {

[string]$FirstName

[string]$LastName

}

Use-Python {

Use-PythonScope {

$Person = [Person]::new()

$Person.FirstName = "Adam"

$Person.LastName = "Driscoll"

Set-PythonVariable -Name "person" -Value $Person

Invoke-Python -Code "person.FirstName + ' ' + person.LastName" -ReturnType ([string])

}

}
