如何抓取pdf的几页？

Question

My code is like this:

df = tabula.read_pdf('test.pdf', pages = ['all'])[0]

df.head()

df.to_excel('test.xlsx')`

When I run it, I have just the first page in my Excel...

Answer 1

You read the whole pdf with all pages but you fetch the erst element.

df = tabula.read_pdf('test.pdf', pages = ['all'])[0]
                                                 ^^^

I think you have to remove that and concat it to get all pages to excel. Something like that:

dfs = tabula.read_pdf(self.file, pages='all')
df = pd.concat(dfs)
df.to_excel("filename.xlsx")
