Given some URL:

url = 'http://test.com/dir1/dir2/dir3/page.html';

Get the contents of the first folder:

'dir1'

Display the following pyramid on the screen:

xxxxx
xxxx
xxx
xx
x

Given a list of events for specific dates, stored in the following structure:

events = [
	{
		'date':  '2019-12-29'
		'event': 'name1'
	},
	{
		'date':  '2019-12-31'
		'event': 'name2'
	},
	{
		'date':  '2019-12-29'
		'event': 'name3'
	},
	{
		'date':  '2019-12-30'
		'event': 'name4'
	},
	{
		'date':  '2019-12-29'
		'event': 'name5'
	},
	{
		'date':  '2019-12-31'
		'event': 'name6'
	},
	{
		'date':  '2019-12-29'
		'event': 'name7'
	},
	{
		'date':  '2019-12-30'
		'event': 'name8'
	},
	{
		'date':  '2019-12-30'
		'event': 'name9'
	},
]

Write code that will remake the data structure into this:

{
	'2019-12-29': ['name1', 'name3', 'name5', 'name7'],
	'2019-12-30': ['name4', 'name8', 'name9'],
	'2019-12-31': ['name2', 'name6'],
}
