mysql-python: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist

Question

I installed mysql using homebrew.

I'm now trying to install mysql-python and I keep getting the error below when I run mysql.

I'm new to programming and don't know enough to identify the problem.

Any help will be appreciated. Thanks.

I figured it out. I forgot to follow the instructions at the top of the homebrew install notes in terminal.

Hope saves time for others who make the same mistake.

Set up databases to run AS YOUR USER ACCOUNT with:
    unset TMPDIR
    mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

To set up base tables in another folder, or use a different user to run
mysqld, view the help for mysqld_install_db:
    mysql_install_db --help

and view the MySQL documentation:
  * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
  * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html

To run as, for instance, user "mysql", you may need to `sudo`:
    sudo mysql_install_db ...options...

Start mysqld manually with:
    mysql.server start

    Note: if this fails, you probably forgot to run the first two steps up above
