# Python3.6+, install the googletrans using:
# pip install googletrans
# import Translator to detect language and translate...
from googletrans import Translator

# Customize service URL
translator = Translator(service_urls=['translate.google.cn'])

		:param text: origin text -> str or list
		:param src: origin language -> str
		:param dest: translation language -> str
		:return: translated text -> str or list

		languages: {‘zh-cn’: ‘chinese (simplified)’, ‘zh-tw’: ‘chinese (traditional)’, ‘en’: ‘english’,
					‘fr’: ‘french’, ‘it’: ‘italian’, ‘ja’: ‘japanese’, ...}
					you can use following statement to supported languages:
						import googletrans
						print(googletrans.LANGUAGES)
	"""

	elif isinstance(text, list):
