I hope this helps you . You could remove the two-step process entirely and just use .Remove which will return:
code :
for (int x = 0; x < cars.Count; x++) 
{ 
    moscowCars.Remove(cars[x].Name); 
}
for (int x = 0; x < cars.Count; x++) 
{ 
    if (!moscowCars.Remove(cars[x].Name))
    {
        // Handle no cars to remove
    }
}
public bool Remove(T item) {
    int index = IndexOf(item);
    if (index >= 0) {
        RemoveAt(index);
        return true;
    }

    return false;
}
moscowCars.RemoveAll(y => y == cars[x].Name);
if (moscowCars.RemoveAll(y => y == cars[x].Name) == 0)
{
    // Handle no cars to remove
}

help you fix your problem I think that it's ok and you can use startswith method if it do what you really want(i am not sure that you really need regEx here - however code below can be easily modified to use regEx):
code :
data = ['text', 'foo2', 'foo1', 'sample']
indeces = (i for i,val in enumerate(data) if val.startswith('foo'))
from re import match
data = ['text', 'foo2', 'foo1', 'sample']
indeces = (i for i,val in enumerate(data) if match('foo', val))

wish help you to fix your issue I have a Dictionary item call "feeds". within the feeds i have a key named "SignatureNumber". This key inside contain a list of array items.
code :
for (NSDictionary * dict in feeds) {

  for (NSNumber * number in deepsightSig) {

    long idFeed = [dict[@"SignatureNumber"] longValue];  /// if your id is too large, using NSString instead.
    long idSig = [number longValue];   /// like NSString = [number stringValue];

    if (idFeed == idSig) { /// if using NSString, it should be: "if ([idFeed isEqualToString:idSig])"
      badIPCount++;
    }
    else {
      goodIPCount++;
    }
  }
}
prints results only when string item index == list item index

should help you out You can use str.maketrans() and str.translate() for these kinds of translation jobs:
code :
trans_tab = str.maketrans(dict(zip(alphabet, special_alphabet)))
name = input('Please insert your name: ')
translated_name = name.translate(trans_tab)
print(translated_name)
In [15]: trans = str.maketrans({
    ...:     'A': 'A ',
    ...:     'm': 'M ',
    ...:     'i': 'I ',
    ...:     'n': 'N ',
    ...:     'e': 'E '
    ...: })

In [16]: input("> ").translate(trans)
> Amine
Out[16]: 'A M I N E '

this will help I had a bit of a wrestle with this problem recently, and the solution turns out to be fairly simple. You can retrieve the "visible list" by using getListAdapter() on the ListActivity, which reflects the current filtered view of the list.
For example, in your ListActivity subclass's onCreate():
