从 .pdf 中提取粗体和带下划线的文本

Question

I need to extract text from pdf. But the pdf has some bold and underlined texts. I tried MyPDF2 but getting error while trying to read those pdfs containing formatted texts.

    import PyPDF2
    pdf_file = open('Downloads/th.pdf','rb')
    read_pdf = PyPDF2.PdfFileReader(pdf_file)
    number_of_pages = read_pdf.getNumPages()
    page = read_pdf.getPage(0)
    page_content = page.extractText()
    print (page_content)

Output

Answer 1

I was using Python 3.6 and the PyPDF2 moduele:

1. Get and install Python 3
2. Install PyPDF2 module using PIP. Run in terminal (or CMD/PowerShell in windows): pip install PyPDF2

3. Run this code in the python console as in the tutorial , for reading the PDF file and extracting the text:

    import PyPDF2 pdfFileObj = open('meetingminutes.pdf', 'rb') pdfReader = PyPDF2.PdfFileReader(pdfFileObj) pageObj = pdfReader.getPage(0) pageObj.extractText()
