Python 谷歌翻译API 无js代码

Google-Translation-API

谷歌翻译API

在网上发现该 API 后通过, 将其中的 JS 转为了 Python

一些示例

print(cn_to_en("中文"))

[[['Chinese', '中文', None, None,
2], [None, None, None, 'Zhōngwén']], [['名词', ['Chinese'], [['Chinese', ['中文', '汉语', '华人', '华
语', '汉'], None, 0.56094915]], '
中文', 1]], 'zh-CN', None, None, [['中文', None, [['Chinese', 1000,
True, False]], [[0, 2]], '中文', 0, 0]], 0.58841187, [], [['zh-CN',
'ja'], None, [0.58841187, 0.41158813], ['zh-CN', 'ja']]]

下面两端代码顺序放在一起即可

Github 可以来个 star 吗?😚
