How to get all columns' names for all the tables in MySQL?

Question

Is there a fast way of getting all column names from all tables in MySQL, without having to list all the tables?

Answer 1

I wrote this silly thing a long time ago and still actually use it now and then:

Basically, it does a "SHOW TABLES", then a "DESCRIBE " on each table, then spits it out as markdown.

Just edit below the "if name" and go. You'll need to have pymysql installed.
