查询没有通过mysq运行

Question

虽然存储在变量中的数据没有将值传递给select查询，但我无法从select查询中检索数据

from flaskext.mysql import MySQL

@app.route("/loginscr/",methods =['POST'])
def loginscr():

    username = request.form['username']
    password = request.form['password']

    print(request.form.to_dict())
    cursor = connection.cursor()
    cursor.execute('Select * from basics where username = %s AND password = %s',(username,password))
    account = cursor.fetchone()
    if account is not None:
        print("Successfull")
    else:
        print("UnSuccessfull")
    return "true"

Answer 1

fetchone()不返回int.Replace

if(account == 1):

与

if account is not None:

或者，更像Python

if account:
