Question

我正在尝试使用其python API运行OCRmypdf。如果不声明语言，则可以运行它。但是，当我尝试声明一种语言时，它将引发错误。 api.py文件使用键入来声明language: List[str] = None，因此我从键入中导入了List并试图声明一个lang变量，这引发了错误。

我的代码：

source = 'fr'; target = 'en'; tess_lang = 'fr'
x: List[str] = ['eng', 'fr']
for dirpath, dirs, files in os.walk('.'):
    print(files)
    for pdf in [file for file in files if '.pdf' in file.lower()]:
        ocrmypdf.ocr(language = x, input_file = pdf, output_file = pdf.rsplit('.', 1)[0]+'_new.pdf', rotate_pages=True, deskew=True, force_ocr = True)

错误：

      5     print(files)
      6     for pdf in [file for file in files if '.pdf' in file.lower()]:

TypeError: language: ['eng', 'fr'] (<class 'list'>)

Answer 1

这似乎是其类型注释中的错误，可能应该是language: Optional[str] = None

要传递多种语言，看来您可以使用language='eng+fr'

“ api”的工作方式是将所有这些参数组合在一起，然后feed them through their commandline parser －仅支持标量值（无List等）

如何使用python的输入模块？
