Python docx报错：'Document' object is not subscriptable 问题求助

我正在学习Python，用python-docx库生成求职信时碰到问题——第一部分代码正常运行，但添加筛选零售及营销职位的逻辑后，出现了Document对象相关错误。检查过文件路径和循环逻辑，也试过把if改成elif，都没解决。附上代码和完整报错信息，求解答。

import docx
for jobs in job_details:
    finance_cl_template = docx.Document('D:\\Desktop\\cl automator\\finance cl template.docx')
    if "(Banking & Financial Services)" in jobs['category']:
        finance_cl_template.paragraphs[2].text = finance_cl_template.paragraphs[2].text.replace('OFD', jobs['title'])
        finance_cl_template.paragraphs[3].text = finance_cl_template.paragraphs[3].text.replace('PGA', jobs['title']).replace('ACC', jobs['recruiter'])
        finance_cl_template.paragraphs[12].text = finance_cl_template.paragraphs[12].text.replace('ACC', jobs['recruiter'])
        finance_cl_template.save(f'D:\\Desktop\\cl automator\\{jobs["title"]} Cover Letter.docx')
    if "(Retail & Consumer Products)" in jobs['category'] or "(Marketing & Communications)" in jobs['category']:
        retail_and_marketing_cl_template = docx.Document('D:\\Desktop\\cl automator\\retail and marketing cl template.docx')
        retail_and_marketing_cl_template[2].text = retail_and_marketing_cl_template.paragraphs[2].text.replace('ZFG', jobs['title'])
        retail_and_marketing_cl_template[5].text = retail_and_marketing_cl_template.paragraphs[5].text.replace('XYZ', jobs['title'])
        retail_and_marketing_cl_template[12].text = retail_and_marketing_cl_template.paragraphs[12].text.replace('ABC', jobs['recruiter'])
        retail_and_marketing_cl_template.save(f'D:\\Desktop\\cl automator\\{jobs["title"]} Cover Letter.docx')

完整报错信息：

Traceback (most recent call last):
  File "D:/Desktop/Python/AI seek cover letter scraper word part3.py", line 130, in <module>
    retail_and_marketing_cl_template[2].text = retail_and_marketing_cl_template.paragraphs[2].text.replace('Spark Pukekohe', jobs['title'])
TypeError: 'Document' object is not subscriptable

问题原因及修复方案 #

报错的核心原因是：Document对象本身不支持下标访问，你在操作零售营销模板时，错误地直接用retail_and_marketing_cl_template[2]来获取段落，正确的方式是通过.paragraphs属性获取段落列表后，再用下标访问具体段落。

修复后的代码如下：

import docx
for jobs in job_details:
    finance_cl_template = docx.Document('D:\\Desktop\\cl automator\\finance cl template.docx')
    if "(Banking & Financial Services)" in jobs['category']:
        finance_cl_template.paragraphs[2].text = finance_cl_template.paragraphs[2].text.replace('OFD', jobs['title'])
        finance_cl_template.paragraphs[3].text = finance_cl_template.paragraphs[3].text.replace('PGA', jobs['title']).replace('ACC', jobs['recruiter'])
        finance_cl_template.paragraphs[12].text = finance_cl_template.paragraphs[12].text.replace('ACC', jobs['recruiter'])
        finance_cl_template.save(f'D:\\Desktop\\cl automator\\{jobs["title"]} Cover Letter.docx')
    if "(Retail & Consumer Products)" in jobs['category'] or "(Marketing & Communications)" in jobs['category']:
        retail_and_marketing_cl_template = docx.Document('D:\\Desktop\\cl automator\\retail and marketing cl template.docx')
        # 修正：添加.paragraphs属性
        retail_and_marketing_cl_template.paragraphs[2].text = retail_and_marketing_cl_template.paragraphs[2].text.replace('ZFG', jobs['title'])
        retail_and_marketing_cl_template.paragraphs[5].text = retail_and_marketing_cl_template.paragraphs[5].text.replace('XYZ', jobs['title'])
        retail_and_marketing_cl_template.paragraphs[12].text = retail_and_marketing_cl_template.paragraphs[12].text.replace('ABC', jobs['recruiter'])
        retail_and_marketing_cl_template.save(f'D:\\Desktop\\cl automator\\{jobs["title"]} Cover Letter.docx')

另外补充一个小优化：可以把模板文件路径定义成变量，避免重复写长路径，提升代码可读性。
