TypeError:translate（）缺少1个必需的位置参数：“text”

Question

几天前我刚刚开始使用python，不幸的是，我不知道这段代码有什么问题。 我正在使用googletrans API将法语翻译成德语。 我的代码非常简单，我看不出有什么问题。我的整个安慰说：

Traceback (most recent call last):
 File "C:\Users\leand\AppData\Local\Temp\atom_script_tempfiles\88ae3f70-767a-11ea-a67f-aff8eb543f99", line 7, in <module>
    t = translator.translate(text,dest ="de", src = "fr")
TypeError: translate() missing 1 required positional argument: 'text'
[Finished in 0.437s]

from googletrans import Translator 
translator = Translator      
text = "je suis"

t = translator.translate(text,dest ="de", src = "fr")

dest是翻译器的目标语言，它是translate函数所需要的。在这种情况下，德语 scr是源语言，在本例中为法语。 文本是要翻译的文本

有人建议在Translator（）之后的开头添加括号，但这只是将我的控制台更改为：

谢谢你阅读我的问题

创建“translator”对象时缺少括号

应该是：

translator = Translator()

这就把“自我”的论点注入了。这就是为什么会出现缺少参数的错误。 https://www.geeksforgeeks.org/self-in-python-class/

如果随后出现JSON解码错误，则很可能是在“Translator”的某个位置输入了错误的参数类型。确保您已经阅读了用法，并且在需要的地方提供了JSON对象作为参数
