正则表达式之疑惑求解

for page in range(1,21):
request_pares(page)运行时出现如下错误：
File "C:\Users\Administrator\Desktop\正则表达式练习之爬取网站多页信息.py", line 27, in <module>
withopen('./data/职位信息.csv','w',encoding='utf-8',newline='') as f:
FileNotFoundError: No such file or directory: './data/职位信息.csv'
有路过的大神帮忙分析一下吗？
和正则表达式无关，FileNotFoundError是在调用文件时path不存在文件导致的，设立路径时请确认path除了最后一个名字以外其他文件夹都存在，比如这个path='./data/职位信息.csv'，要确定文件夹data确实存在才行
