python判断word文档是否超过2页，超过2页的进行双面打印。

A：可以使用Python的第三方库`python-docx`来实现。代码如下：

import docx

# 打开Word文档
doc = docx.Document("example.docx")

# 获取文档页数
num_pages = len(doc.sections)

# 判断是否超过2页
if num_pages > 2:
    # 设置双面打印
    for section in doc.sections:
        section.start_type = docx.enum.section.WD_SECTION_START.NEW_PAGE
        section.orientation = docx.enum.section.WD_ORIENT.LANDSCAPE
        section.page_width = docx.shared.Inches(11)
        section.page_height = docx.shared.Inches(8.5)
        section.left_margin = docx.shared.Inches(1)
        section.right_margin = docx.shared.Inches(1)
        section.top_margin = docx.shared.Inches(1)
        section.bottom_margin = docx.shared.Inches(1)
        section.different_first_page_header_footer = False
        section.header_distance = docx.shared.Inches(0.5)
        section.footer_distance = docx.shared.Inches(0.5)
        section.different_odd_and_even_pages_header_footer = True

# 保存文档
doc.save("example.docx")

首先使用`docx`库打开Word文档，计算文档的页数`num_pages`。如果大于2页，则遍历每个节(section)，设置双面打印的参数，并将`different_odd_and_even_pages_header_footer`设置为True，实现奇偶页不同的页眉和页脚。最后保存文档。
