Here is a Python code to remove all the punctuation from a given sentence:

```
import string

def remove_punctuation(sentence):
    """
    This function removes all the punctuation from a given sentence
    """
    translation_table = str.maketrans('', '', string.punctuation)
    return sentence.translate(translation_table)
```

You can use this function by passing a sentence as a string argument and it will return the same sentence without any punctuation.
