I have a list of tuples:

```
lst=[(6, 'C'), (6, 'H'), (2, 'C'), (2, 'H')]

```

And a dictionary:

```
dct={'6C': (6, 'C'), '6H': (6, 'H'), '9D': (9, 'D'), '10D': (10, 'D'), '11S': (11, 'S'), '2C': (2, 'C'), '2H': (2, 'H')}

```

How can I remove the elements from the dictionary that are in the list? In this example my desired output would be: 

```
dct2={'9D': (9, 'D'), '10D': (10, 'D'), '11S': (11, 'S')}

```
