instagram用户多少个帖子

Question

import requests
from bs4 import BeautifulSoup
def scrapeInstagram(soup1):
    insta_Data = []
    for meta in soup1.find_all(name='meta', attrs={"property":"og:description"}):
        insta_Data = meta['content'].split()


    followers = insta_Data[0]
    following = insta_Data[2]
    posts = insta_Data[4]
    print(f"insta User > {insta_user}, Posts > {posts}")

while True:
    insta_user = input("enter user : ")
    insta_URL = f"https://www.instagram.com/{insta_user}"
    insta_Page = requests.get(insta_URL)
    soup = BeautifulSoup(insta_Page.text, "html.parser")
    if(insta_Page.status_code == 200):
        scrapeInstagram(soup)
    else:
        print("no exist"+"  "+ insta_user)

代码显示instagram用户有多少帖子，我如何更改（insta user = input）以打开文本文件并检查每个用户他们有多少帖子 /我需要以下输出：

users.txt : 
0afd
aa
ser
test435

oafd > 12 post
aa > 5 post
ser > 1 post 
test435 > not exist
