Piece of my code:

@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegisterForm(request.form)
    if request.method=='POST' and form.validate():
        name =  form.name.data
        email = form.email.data
        username = form.username.data
        password = sha256_crypt.encrypt(str(form.password.data))

        c.execute("INSERT INTO users(name,email,username,password)
        VALUES(?,?,?,?)", (name, email, username, password))

        conn.commit

        conn.close()

The error:
 File "C:Usersapp.py", line 59, in register c.execute("INSERT INTO users(name,email,username,password) VALUES(?,?,?,?)", (name, email, username, password))
