python小白关于把pdf转化为excel的提问

[xsnhnewyoung]

import pdfplumber
from openpyxl import Workbook
wb = Workbook()
ws = wb.active
path="c:\Users\NING MEI\Desktop\filename.pdf"
pdf = pdfplumber.open(path)
print('\n')
print('开始读取数据')
print('\n')
print(pdf.pages[1].extract_tables()[0][0])
ws.append(pdf.pages[1].extract_tables()[0][0])
for page in pdf.pages:
# print(page.extract_text())
for table in page.extract_tables():
# print(table)
for row in table:
if "序号" not in row:
# print(type(row))
rowlist=str(row).replace("[","",).replace("]","").replace("'","").replace("\\n","").split(",")
print(rowlist)
ws.append(rowlist)
print('---------- 分割线 ----------')
pdf.close()
# 保存Excel表
wb.save('filename.xlsx')
print('\n')
print('写入excel成功')
print('保存位置：')
print('filename.xlsx')
print('\n')

报错
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

请问大神们这是什么原因？

在那一行出错？ pdf = pdfplumber.open(path) 如果是这行。 把 path="c:\Users\NING MEI\Desktop\filename.pdf" 改成 path="c:/Users/NING MEI/Desktop/filename.pdf" 试试
