printing - How to count similar domains in emails and print every domain only once[python]? -

-

I have 10 hotmail emails, 4 Gmail, 3 mails. I want to analyze the list of emails and print out how many domains (Hotmail, Gmail, etc.) and impressions. But I do it in a very bruteforce way. I know that Python has an elegant short code (like Iteratollos, Islice, Xrange)

Hotmail: 10 Gmail: 4 mail.com: 3

But I get this:

Hotmail 10 Hotmail 10 ... Hotmail 10 Gmail 4 Gmail 4 Gmail 4 Gmail 4 AD 

  DRT count_domains (email): For e-mail in email: current_email = Email.split ("@", 2) [1] # partition @, john@mail.com = & gt; Current_emain_counter = 0 for email 2 in Mail.com, # 2 index (current_email) in the list. If current_email == email2.split ("@", 2) [1]: current_domain_counter = current_domain_counter + 1 # print (current_email_ current_domain_counter) )) If you put all the stars in a list, myList says, "You can make it unique by using  
  uniqueList = list (set of myList)  
 
 After this, you can count the events used, e.g. 
 
  countFirst = myList.count (unique list [0])  
 
 You can put things together, such as 
 set in the domain For 
  [[domain, myList.count (domain)]

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
