While developing a website, you detect that some of the members have troubles logging in. Searching through the code you find that all logins ending with a "\_" make problems. So you want to write a function that takes an array of pairs of login-names and e-mails, and outputs an array of all login-name, e-mails-pairs from the login-names that end with "\_".
If you have the input-array:
```
[ [ "foo", "foo@foo.com" ], [ "bar_", "bar@bar.com" ] ]
```
it should output
```
[ [ "bar_", "bar@bar.com" ] ]
```
You *have to* use the *filter*-method which returns each element of the array for which the *filter*-method returns true.
```python

```
def search_names(logins):
    return list(filter(lambda l: l[0].endswith("_"), logins))
def search_names(logins):
    return list(filter(lambda l: l[0].endswith("_"), logins))
