Got a list which contains tuples of Strings and I need to check if the given string is within any of the tuples or not, I'm able to do that with my piece of code but I'm looking for a pythonic way of doing this and also the "in" doesn't work here like 'GivenName' in namelst.

Tuple:

```
namelst= [('Travolta', 'Surname'), ('John', 'GivenName'), ('Joe', 'Nickname')]

```

Traditional Code:

```
for items in namelst:
    if('GivenName' in items):
        //Do Something

```
