This might help you I filled the Grades list box at designed time with A B C D F' lbStudents is a list box. What the problem calls lstGrades I called lbGrades. No difference Except name.
code :
 Public Class Form1
        Private Sub lbGrades_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lbGrades.SelectedIndexChanged
            'Clear the list before adding new students
            lbStudents.Items.Clear()
            Dim strNames() As String = {"Helen", "Peter", "Yolanda", "Carl", "Jennifer", "Charles", "Addison", "Aiden", "Treyson", "Sydney", "Jacob", "Nancy", "George", "Ursula", "Jack"}
            Dim strGrades() As String = {"A", "B", "B", "A", "D", "F", "A", "B", "A", "B", "F", "C", "C", "B", "D"}
            'Using a variable for the size of your arrays makes the code more generic so it could be
            'used for different size arrays.
            Dim n As Integer = strGrades.Count - 1
            Dim itgCount As Integer = 0
            'This and the matching .EndUpdate prevents the list box from repainting on each iteration
            'Not important in this example but could be very important for long list additions
            lbStudents.BeginUpdate()
            'loop through the idexes of the arrays
            'VB arrays are zero based = the first element is index 0
            For index As Integer = 0 To n
                'Check the grades array for the item selected in the list box
                If strGrades(index) = lbGrades.SelectedItem Then
                    'if found, increment the counter
                    itgCount += 1
                    'find the name of the student by using the same index as the grades array
                    'this is the value of parallel arrays
                    'Add the name to the other list box
                    lbStudents.Items.Add(strNames(index))
                End If
            Next
            lbStudents.EndUpdate()
            'Display the count in a label using an interpolated string
            lblCount.Text = $"The number of students with Grade {lbGrades.SelectedItem} is {CStr(itgCount)}."
        End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        'This satisfies the requirement in b. of the problem
        lbGrades.SelectedItem = "A"
    End Sub
End Class

I wish this help you You can use Python regexes to find all matches instead of iterating over the string:
code :
import re

#your pattern here
pattern = r"\=\"[a-zA-Z0-9\+\!\@\#\$\%\^\&\*\(\)\_]*\.swf\""

#string to search
test_str = "<name=\"echo\" value=\"2010a.swf\"><ie=tango v=\"bolder.swf\"><val==\"backstreetboys+AreBack.swf\">"

#use re.findall() to get all matches
m = re.findall(pattern, test_str)

#print the matches
if m:
    print("Found matches:")
    for i in enumerate(m):
        print(i)

this will help Yes, this available in their API docs. It tends to be put under the expansion of what is available for multi-currency.
e.g.
code :
MULTICURRENCY DISABLED
debit -> debt_amt
credit -> credit_amt 
currency -> N/A 
exchange rate -> N/A 
open balance -> nat_open_bal 
amount -> subt_nat_amount 
tax amount -> tax_amount 
taxable amount -> net_amount

MULTICURRENCY ENABLED 
debit -> debt_home_amt 
credit -> credit_home_amt 
currency -> currency 
exchange rate -> exch_rate 
open balance -> nat_home_open_bal 
amount -> subt_nat_home_amount 
tax amount -> home_tax_amount 
taxable amount -> home_net_amount
