如果我通过调用运算符 ($val = & python myscript.py) 从 Powershell 运行 Python 脚本 如何将数组从 Python 传递到 $val

以下是一个示例脚本:

import os
import sys
import pathlib
import json
from contextlib import redirect_stderr
from fontTools import ttLib
from fontmeta import FontMeta

# Check for commandline argument
if len(sys.argv) == 1:
    print('No argument was supplied.')
    exit(0)

fontfile = sys.argv[1]


def font_name(font_path, name_idx):
    font = ttLib.TTFont(font_path, ignoreDecompileErrors=True)
    with redirect_stderr(None):
        names = font['name'].names

    details = {}
    for x in names:
        if x.langID == 0 or x.langID == 1033:
            try:
                details[x.nameID] = x.toUnicode()
            except UnicodeDecodeError:
                details[x.nameID] = x.string.decode(errors='ignore')
    # details[4] = Full Name
    # details[1] = Family Name
    # details[2] = Style Name
    return details[name_idx]


meta_instance = FontMeta(fontfile)

metadata = meta_instance.get_full_data()

fontFullName           = font_name(fontfile,4)
fontFamily             = font_name(fontfile,1)
fontStyle              = font_name(fontfile,2)
fontVers               = metadata[5]['value'];
fontVers               = fontVers.replace('Version ',"v")
fontLang               = metadata[1]['language']['value'];
fontUniqueID           = metadata[3]['value']
fontPostscriptName     = metadata[6]['value']
fontPostscriptEncoding = metadata[6]['encoding']['value']
fontDesigner           = metadata[9]['value']
fontLicenseURL         = metadata[14]['value']

print('Full Name:     ' + fontFullName)
print('Family:        ' + fontFamily)
print('Style:         ' + fontStyle)
print('Version:       ' + fontVers)
print('Language:      ' + fontLang)
print('UniqueID:      ' + fontUniqueID)
print('License URL:   ' + fontLicenseURL)
print('Font Designer: ' + fontDesigner)

Output:个

Full Name:     Sharp Sans Bold
Family:        Sharp Sans
Style:         Bold
Version:       v1.001
Language:      English/United States
UniqueID:      1.001;2016;SHRP;SharpSans-Bold
License URL:   http://www.sharptype.co
Font Designer: Lucas Sharp

PS1:

& "D:\Dev\Python\00 VENV\FontTools\Scripts\Activate.ps1"

$val = python "D:\Dev\Python\Font Scripts\GetFontInfo.py" "D:\Fonts\00 Test\SharpSans-Bold.otf"

Write-Host "`$val:" $val -ForegroundColor Green

现在，Python代码只是打印值.我的ps脚本将打印的值作为字符串 echo .除了打印之外，还有什么方法可以将这些值传递给PowerShell--即以数组形式？

或者，我应该返回JSON并在PowerShell中解析它吗？

如果有任何帮助，我很感激.
