怎么使用Python导出PDF指定页数

我本来想使用WPS的，但是发现要会员，不如直接写一个。
不过过程中还是遇到了一些麻烦的，需要配置Scoop,poppler。

import os
from pdf2image import convert_from_path

def export_pdf_pages_to_png(pdf_path, start_page, end_page, output_folder):
    images = convert_from_path(pdf_path, first_page=start_page, last_page=end_page)

    if not os.path.exists(output_folder):
        os.makedirs(output_folder)

    for i, image in enumerate(images):
        image_path = os.path.join(output_folder, f"page_{start_page + i}.png")
        image.save(image_path, "PNG")
        print(f"Page {start_page + i} saved as {image_path}")

pdf_file = "计网第五版习题答案.pdf"
start_page = 155
end_page = 192
output_folder = "output"

export_pdf_pages_to_png(pdf_file, start_page, end_page, output_folder)

可修改内容,相对路径：

pdf_file = 

start_page

end_page

output_folder =
