`IPython.utils.text:SList.grep`

Signature

def grep(self, pattern: str | Callable[[Any], re.Match[str] | None], prune: bool = False, field: int | None = None) → Self

Return all strings matching 'pattern' (a regex or callable)

This is case-insensitive. If prune is true, return all items NOT matching the pattern.

If field is specified, the match must occur in the specified whitespace-separated field.

Examples

a.grep( lambda x: x.startswith('C') )
a.grep('Cha.*log', prune=1)
a.grep('chm', field=-1)
