from sqlalchemy import create_engine

connection = create_engine('mysql://user:passwd@localhost:3306/db').connect()

如何动态获取表格列名称?在这种情况下 id 和 name

how i can get TABLES COLUMNS NAMES dynamically? in this case id and name

推荐答案

您可以通过调用 result.keys() 来查找列，也可以通过调用 v.keys 来访问它们() 在 for 循环中.

You can either find the columns by calling result.keys() or you can access them through calling v.keys() inside the for loop.

这是一个使用 items() 的例子:

Here's an example using items():

for v in result:
    for column, value in v.items():
        print('{0}: {1}'.format(column, value))
