我希望pdfplumber从用户给出的随机pdf中提取文本。问题是pdfplumber还会从每个页面中提取标题文本或标题。如何编写pdfplumber程序,使其不读取页眉(标题)和页码(或页脚,如果可能)?
下面是代码:
import pdfplumber
all_text = ""
pdf = pdfplumber.open(file)
for pdf_page in pdf.pages:
one = pdf_page.extract_text()
all_text = all_text + '\n' + str(one)
print(all_text)其中file是PDF文档...

我觉得你做不到。
但是,您可以使用crop方法裁剪文档。这样,您可以只提取页面裁剪部分的文本,而不提取页眉和页脚。当然,这种方法要求您提前知道页眉和页脚的高度。
下面是对余弦的解释:
x0 = % Distance of left side of character from left side of page.
top = % Distance of top of character from top of page.
x1 = % Distance of right side of character from left side of page.
bottom = % Distance of bottom of the character from top of page.代码如下:
# Get text of whole document as string
crop_coords = [x0, top, x1, bottom]
text = ''
pages = []
with pdfplumber.open(filename) as pdf:
for i, page in enumerate(pdf.pages):
my_width = page.width
my_height = page.height
# Crop pages
my_bbox = (crop_coords[0]*float(my_width), crop_coords[1]*float(my_height), crop_coords[2]*float(my_width), crop_coords[3]*float(my_height))
page_crop = page.crop(bbox=my_bbox)
text = text+str(page_crop.extract_text()).lower()
pages.append(page_crop)https://stackoverflow.com/questions/66900539
