Python try except finally invalid 语法错误

Question

所以我试图在 python 中使用这个异常处理。我为此使用 python2.7 和烧瓶。另外，我对 python 和 flask 都不熟悉，所以我一定是在这里做错了什么。

if test:
    cursor = conn.cursor()
    try:
        print cursor.execute("INSERT INTO Users (email, password, firstname, lastname, home, gender, dob, bio, profile_Image) VALUES ('{0}', '{1}', '{2}', '{3}', '{4}', '{5}', '{6}', '{7}', '{8}')".format(email, password, firstname, lastname, home, gender, dob, bio, photo_data))
        conn.commit()
        #log user in
        user = User()
        user.id = email
        flask_login.login_user(user)
        uid = getUserIdFromEmail(flask_login.current_user.id)
        today = str(date.today())
        print today
    except Exception as e:
        print e
        print "Something Went wrong"
        return flask.redirect(flask.url_for('register'))
    print cursor.execute("INSERT INTO Album (uid, aname, adate, cover) VALUES ('{0}', 'default', '{1}', '{2}')".format(uid, today, photo_data))
    aid = getAIDfromAname('default', uid)
    cursor.execute("INSERT INTO Photo (uid, aid, data, caption) VALUES ('{0}', '{1}', '{2}', 'profile')".format(uid,aid,photo_data))
    cursor.execute("INSERT INTO Scoreboard (uid) VALUES ('{0}')".format(uid))
    conn.commit()
    finally:
        cursor.close()
    return render_template('profile.html', firstname=firstname, message='Account Created!')

else:
    print "couldn't find all tokens"
    return render_template('register.html', message='Email Already Exists')

然后如果我运行应用程序

它会给我这个错误

  File "app.py", line 540
finally:
      ^SyntaxError: invalid syntax

我想知道为什么它会给我错误：/

if test:
    cursor = conn.cursor()
    try:
        print cursor.execute("INSERT INTO Users (email, password, firstname, 
lastname, home, gender, dob, bio, profile_Image) VALUES ('{0}', '{1}', '{2}', 
'{3}', '{4}', '{5}', '{6}', '{7}', '{8}')".format(email, password, firstname, 
lastname, home, gender, dob, bio, photo_data))
        conn.commit()
        #log user in
        user = User()
        user.id = email
        flask_login.login_user(user)
        uid = getUserIdFromEmail(flask_login.current_user.id)
        today = str(date.today())
        print today
    except Exception as e:
        print e
        print "Something Went wrong"
        print cursor.execute("INSERT INTO Album (uid, aname, adate, cover) VALUES ('{0}', 'default', '{1}', '{2}')".format(uid, today, photo_data))
        aid = getAIDfromAname('default', uid)
        cursor.execute("INSERT INTO Photo (uid, aid, data, caption) VALUES ('{0}', '{1}', '{2}', 'profile')".format(uid,aid,photo_data))
        cursor.execute("INSERT INTO Scoreboard (uid) VALUES ('{0}')".format(uid))
        conn.commit()
        return flask.redirect(flask.url_for('register'))
    finally:
        cursor.close()
    return render_template('profile.html', firstname=firstname, message='Account 
Created!'))

else:
    print "couldn't find all tokens"
    return render_template('register.html', message='Email Already Exists'

这行得通。 except 块内第 "print cursor.execute" 行的缩进不正确。
