Python 文件目录语法不正确与编码不一致

问题1

import requests

def iqiyi_spider(url,begin_page,end_page):
    for page in range(begin_page,end_page+1):
        url=url+str(page)+"--iqiyi--.html"
        file_name="第"+str(page)+"页"
        response=requests.get(url)
        write_page(response,file_name)
        
def write_page(response,file_name):
    response.encoding="utf-8"
    print("正在保存....")
    with open("E:\python programs"+file_name,"w") as f:
              f.write(response.text)
if __name__=="__main__":
    url="https://list.iqiyi.com/www/1/1--------------"
    begin_page=int(input("输入爬取的开始页数："))
    end_page=int(input("输入爬取的结束页数："))
    iqiyi_spider(url,begin_page,end_page)

必须要将文件写的编码与写入内容的编码一致，要加上encoding=“utf-8”
【解决】

    with open("E:\python programs./"+file_name,"w",encoding="utf-8") as f:
              f.write(response.text)

问题2

运行成功后发现目标目标没有生成相应文件
【原因】：目录格式不正确

with open("E:\python programs"+file_name,"w") as f:

【解决】：加上 ./

    with open("E:\python programs./"+file_name,"w",encoding="utf-8") as f:
