假设您已安装MySQL(使用HomeBrew的macOS使用说明here),您需要:
pip3 install ipython-sql
pip3 install mysqlclient
现在您应该能够运行这些单元并获得打印精美的HTML输出:
# %%
%load_ext sql
# %%
%sql mysql+mysqldb://<user>:<password>@localhost/<dataBase>
# %%
%%sql
SELECT *
FROM <table>;

import os
import pymysql
import pandas as pd
host = os.getenv('MYSQL_HOST')
port = os.getenv('MYSQL_PORT')
user = os.getenv('MYSQL_USER')
password = os.getenv('MYSQL_PASSWORD')
database = os.getenv('MYSQL_DATABASE')
conn = pymysql.connect(
host=host,
port=int(3306),
user="root",
passwd=password,
db="[YOUR_DB_NAME]",
charset='utf8mb4')
df = pd.read_sql_query("SELECT * FROM YOUR_TABLE",
conn)
df.tail(10)

是的,可以。您可以使用MySQL Connector库。只需使用pip安装它,然后就可以使用它与数据库进行交互。请参见下面的示例代码:
import mysql.connector
db = mysql.connector.connect(
host="localhost",
user="mamp",
passwd=""
)
print(db)
