Question

在做作业问题并按照他们的指示键入代码后，我不得不猜测打印功能。当我运行代码时，出现元组错误，但是我已经按照他们的意愿键入了它。我可能会错了，但我无法结束

import sqlite3

def find_details(id2find):
    db = sqlite3.connect("surfersDB.sdb")
    dbrow_factory = sqlite3.Row
    cursor = db.cursor()
    cursor.execute("select * from surfers")
    rows = cursor.fetchall()
    for row in rows:
        if row['id'] == id2find:
            s = {}
            s['id'] = int(row['id'])
            s['name'] = row['name']
            s['country'] = row['country']
            s['average'] = str(row['average'])
            s['board'] = row['board']
            s['age'] = int(row['age'])
            cursor.close()
            return(s)
        cursor.close()
        return({})
lookup_id = int(input("Enter the id of the surfer: "))
surfer = find_details(lookup_id)
if surfer:
    print("ID:         " + surfer['id'])
    print("Name:       " + surfer['name'])
    print("Country:    " + surfer['country'])
    print("Average:    " + surfer['average'])
    print("Board type: " + surfer['board'])
    print("Age:        " + surfer['age'])

如何阅读类型错误：元组索引以解决该问题？
