Using the World-X database found here: dev.mysql.com/doc/index-other.html
Write a Python script to increase the population of each city in the world_x database by 10% (rounded).
First, add a new column to the world_x city table using the following MySQL command:
- ALTER TABLE `world_x`.`city` ADD COLUMN `Population` DOUBLE NULL DEFAULT NULL AFTER `Info`;
The existing population data are stored as JSON datatype in the city table in a field named Info. You learned about JSON data types in Module 2. To obtain the population data from the Info column in the city table, run the following MySQL command:
- select info->$.Population from city
Your Python script should do the following:
- Copy the population data from the Info column into the Population column,
- Increase the population by 10% in the Population column, and
- List the population before the increase and the population after it was increased.
