Question

我正在尝试将值插入到创建的表中但是当我这样做时，它给我一个错误，说明未定义的变量但我已在主函数中声明了它，并且值已分配给那些变量

这是我的代码。＃！的/ usr / bin中/ python3

import requests
import sqlite3
def get_info(url):
    response = requests.get(url)
    page = response.json()
    name = page['name']
    category = page['category']
    link = page['link']
    location = page['location']['city']
    likes = page['likes']
    checkins = page['checkins']
    return name,category,link,location,likes,checkins

def main():
    link = 'https://graph.facebook.com/Indiatoday'
    p_name,p_cat,p_link,p_loc,p_likes,p_check = get_info(link)
    print ('the page details are '+p_name,p_cat,p_link,p_loc,p_likes,p_check)

db = sqlite3.connect('page.db')
db.execute('''CREATE TABLE IF NOT EXISTS page_info (
           id INTEGER PRIMARY KEY,
           name TEXT,
           category TEXT,
           link TEXT,
           location TEXT,
           likes INTEGER,
           checking INTEGER)''')
print ('table created successfully')
db.execute('''INSERT INTO page_info (name, category, link, location, likes,Checking) VALUES(?,?,?,?,?,?)''',(p_name,p_cat,p_link,p_loc,p_likes,p_check))
db.commit()

if __name__ == "__main__": main()

收到错误消息“NameError：name'p_name'未定义” 如果有人能让我知道我在这里做错了会很有帮助。我知道它是一个简单的变量定义，但我找不到它

该行

db.execute('''INSERT INTO page_info (name, category, link, location, likes,Checking) VALUES(?,?,?,?,?,?)''',(p_name,p_cat,p_link,p_loc,p_likes,p_check))

在声明任何变量之前执行（因为它没有缩进，因此不属于main()）。我认为你需要缩进整个块：

def main():
    link = 'https://graph.facebook.com/Indiatoday'
    p_name,p_cat,p_link,p_loc,p_likes,p_check = get_info(link)
    print ('the page details are '+p_name,p_cat,p_link,p_loc,p_likes,p_check)

    db = sqlite3.connect('page.db')
    db.execute('''CREATE TABLE IF NOT EXISTS page_info (
               id INTEGER PRIMARY KEY,
               name TEXT,
               category TEXT,
               link TEXT,
               location TEXT,
               likes INTEGER,
               checking INTEGER)''')
    print ('table created successfully')
    db.execute('''INSERT INTO page_info (name, category, link, location, likes,Checking) VALUES(?,?,?,?,?,?)''',(p_name,p_cat,p_link,p_loc,p_likes,p_check))
    db.commit()

将值分配到表中时未定义的变量
