# Create automation to remove snapshots from VMs older than 30 days. The automation should
# send a report via email on the operations it performed. 
#
# Rules: 
# 1.      Please complete within 4 days 
# 2.      Should be done in standalone code without the use of orchestration or automation
#         suites like vRA or vRO 
# 3.      You can use PowerShell or Python
# 4.      Please store publically with us on GitHub or Bitbucket, (or any public repo) and
#         be prepared to demo if needed
#
#---------------------------------------------------------------------------------------------------------------------------#
#
 
# start app
# get date and time
# has a new day happened?
#     if so send email of log of events
# 
# get time
# get second
# if second is odd show a ♥ after time.
# if second is even show a · after time.
# display date & time & special character
