trigger CreateAccountFromLead on Lead (after insert) {
	// create a List that is initially empty
    List<Account> newAcct = new List<Account>();
    
    for (Lead newLead : Trigger.new) {
        Account accLoop = new Account(); // create a new Account type variable
        accLoop.Name = newLead.LastName; // the Account's Name will be the Lead's LastName
    	
        newAcct.add(accLoop); // use the add method to add that Account to the newAcct list
    }
    
    insert newAcct; // bulkification means you don't do DML statements within a FOR loop
