I would like to practice OOP
(I have made below example working but not use python and not OOP)
below procedure is my beginning but got stuck now .
Question1: if I have 10000+ applications ,means I will need to create 10000+ instance ?
me: use loop to create instances ? cost lots of memory ?
Question2: How can I only get instance which status is false from all instance?
me: use another list to record the status which is false while using loop to create new instance?
Example: install 30 applications if my computer not install
*Environment: Python, Windows7
*my procedure:
class app:
def __init__(self,name , guid , path ):
....self.application_name = name
....self.application_guid = guid
....self.execution_path = path
....self.status = self.is_installed()
def is_installed():
....import winreg
....read GUID in registry HKLM/..../uninstall/
....if no exception then return True
....else return False
what I did now without OOP
array[1000][3]={{"MSSQL","{XXXX-XXX}","C:"},.....}
(store application’s name, guid, path)
Function()
# use loop to check all applications' status and return another array(B)
# process installation according to array(B)
