关于python编程中路径错误导致文档无法写入的解决方案
在编写python程序时，有时会遇到因路径错误而无法将文档写入指定路径的问题。今天，我们将讨论如何解决这种问题，特别是在将多张图片自动排版并写入word文档的过程中。
首先，展示一下实现这一功能的代码：
import os
from pil import image
from docx import document
from docx.shared import inches
from docx.enum.text import wd_paragraph_alignment
from docx.oxml import oxmlelement
def create_word_document(image_folder, output_path):
# 获取图片文件列表
image_files = [f for f in os.listdir(image_folder) if f.lower().endswith(('.png', '.jpg', '.jpeg', '.gif', '.bmp'))]
if not image_files:
print("未找到任何图片文件。")
return
# 创建word文档
doc = document()
doc.add_heading('照片', level=1).alignment = wd_paragraph_alignment.center
# 每页排版两张照片
photos_per_page = 2
for i, image_file in enumerate(image_files, start=1):
if i % photos_per_page == 1:
# 添加新的一页
section = doc.sections[-1]
footer = section.footer
footer.paragraphs[0].clear() # 清除页脚原有内容
footer.paragraphs[0].add_run(f"第 {i // photos_per_page + 1} 页").alignment = wd_paragraph_alignment.center
doc.add_page_break()
# 添加图片和备注
img_path = os.path.join(image_folder, image_file)
img = image.open(img_path)
doc.add_picture(img_path, width=inches(3.0))
doc.add_paragraph(f"序号：{i}")
doc.add_paragraph("备注：")
# 保存word文档
doc.save(output_path)
print(f"word文档已保存至: {output_path}")
if __name__ == "__main__":
# 指定图片文件夹和输出word文档路径
image_folder_path = "d:anzhuang/python/ima"
output_word_path = "d:anzhuang/python/output/"
create_word_document(image_folder_path, output_word_path)运行上述代码时，如果遇到类似下面的错误：
d:\anzhuang\python\python.exe c:/users/admin/pycharmprojects/pythonproject/lianxi3.py traceback (most recent call last): file "c:\users\admin\pycharmprojects\pythonproject\lianxi3.py", line 51, increate_word_document(image_folder_path, output_word_path) file "c:\users\admin\pycharmprojects\pythonproject\lianxi3.py", line 40, in create_word_document doc.save(output_path) file "d:\anzhuang\python\lib\site-packages\docx\document.py", line 151, in save self._part.save(path_or_stream) file "d:\anzhuang\python\lib\site-packages\docx\parts\document.py", line 106, in save self.package.save(path_or_stream) file "d:\anzhuang\python\lib\site-packages\docx\opc\package.py", line 151, in save packagewriter.write(pkg_file, self.rels, self.parts) file "d:\anzhuang\python\lib\site-packages\docx\opc\pkgwriter.py", line 27, in write phys_writer = physpkgwriter(pkg_file) file "d:\anzhuang\python\lib\site-packages\docx\opc\phys_pkg.py", line 109, in __init__ self._zipf = zipfile(pkg_file, "w", compression=zip_deflated) file "d:\anzhuang\python\lib\zipfile.py", line 1239, in __init__ self.fp = io.open(file, filemode) permissionerror: [errno 13] permission denied: 'd:anzhuang/python/output/'
我们尝试通过提升管理员权限来解决无法写入给定路径的问题，但仍然未能解决。这里我们来看看问题出在哪里。
经过仔细检查，发现问题在于输出路径的写法。原代码中的路径是：

output_word_path = "d:anzhuang/python/output/"
正确的方式应该是：
output_word_path = "d:/anzhuang/python/output/"
在windows系统中，当路径是相对盘符（例如，d:）时，必须在盘符后紧跟一个/，否则系统会将路径解释为当前工作目录下的相对路径，而不是绝对路径。
因此，修改路径后，代码应如下所示：
if __name__ == "__main__":
# 指定图片文件夹和输出Word文档路径
image_folder_path = "d:/ANZHUANG/PYTHON/IMA"
output_word_path = "d:/ANZHUANG/PYTHON/output/"
create_word_document(image_folder_path, output_word_path)通过这个简单的修改，应该能够解决路径错误导致的文档无法写入问题，并成功实现将多张图片拖入固定文件夹后自动用word进行排版的功能。
