【问题描述】:
代码是
from PyPDF2 import PdfFileReader
with open('HTTP_Book.pdf','rb') as file:
pdf=PdfFileReader(file)
pagedd=pdf.getPage(0)
print(pagedd.extractText())
此代码引发如下所示的错误:
TypeError: ord() expected string of length 1, but int found
我在互联网上搜索并找到了这个Troubleshooting "TypeError: ord() expected string of length 1, but int found" 但这并没有多大帮助。我知道这个错误的背景是什么,但不确定它与这里有什么关系?
尝试更改 pdf 文件,它工作正常。那么出了什么问题:pdf文件或PyPDF2无法处理?根据文档,我知道这种方法不太可靠:
这对某些 PDF 文件效果很好,但对其他文件效果不佳,具体取决于所使用的生成器
应该如何处理?

我已将您的问题编辑为独立存在。 SO 是一个问答网站,而不是论坛,所以参考其他问题是可以的,但依靠它们来保持连续性是不行的。我建议的唯一进一步更改是添加指向您的 pdf 文件的链接。
