python django连接不上数据库，谁能帮我看看，是什么问题？

Question

电脑环境：window7 ,python版本3.4.2， django2.0.13 ,pycharm版本2020.1。
在本地搭建的mysql数据库：MySQL Server 5.1。

setting.py文件中的数据库配置如下：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'blog',
        'USER': 'root',
        'PASSWORD': 'huguozhi',
        'HOST': 'localhost',
        'PORT': "3306",
    }
}

项目下的__init__.py如下，并且已经下载好了pymysql库（版本1.0.0）：

import pymysql
pymysql.install_as_MySQLdb()

启动项目 错误代码如下：

进程已结束，退出代码 1

谁能帮我看看是什么问题啊？

Answer 1

python版本升级到3.6以上, 或者把pymysql退到合适的版本.

Answer 2

看错误提示

File "D:\Program Files\JetBrains\huguozhi\venv\lib\site-packages\pymysql\connections.py", line 206

):
^

SyntaxError: invalid syntax

应该是这个文件206行有问题，应该是这个pymysql用了python3.4以上的语法导致的

建议安装新的python，3.4有点老了
