feed.api.string.operations module¶
operations.py contain functions for streaming string operations.
-
feed.api.string.operations.capitalize(s: feed.core.base.Stream[str][str]) → feed.core.base.Stream[str][str][source]¶ Computes the capitalization of a stream.
Parameters: s (Stream[str]) – A string stream. Returns: A capitalized string stream. Return type: Stream[str]
-
feed.api.string.operations.cat(s: feed.core.base.Stream[str][str], word: str) → feed.core.base.Stream[str][str][source]¶ Computes the concatenation of a stream with a word.
Parameters: - s (Stream[str]) – A string stream.
- word (str) – A word to concatenate with the s.
Returns: A concatenated string stream.
Return type: Stream[str]
-
feed.api.string.operations.endswith(s: feed.core.base.Stream[str][str], word: str) → feed.core.base.Stream[bool][bool][source]¶ Computes the boolean stream of a string ending with a specific value.
Parameters: - s (Stream[str]) – A string stream.
- word (str) – A word that a string value can end with.
Returns: A boolean stream.
Return type: Stream[bool]
-
feed.api.string.operations.lower(s: feed.core.base.Stream[str][str]) → feed.core.base.Stream[str][str][source]¶ Computes the lowercase of a string stream.
Parameters: s (Stream[str]) – A string stream. Returns: A lowercase string stream. Return type: Stream[str]
-
feed.api.string.operations.slice(s: feed.core.base.Stream[str][str], start: int, end: int) → feed.core.base.Stream[str][str][source]¶ Computes the substring of a string stream.
Parameters: s (Stream[str]) – A string stream. Returns: A substring stream. Return type: Stream[str]
-
feed.api.string.operations.startswith(s: feed.core.base.Stream[str][str], word: str) → feed.core.base.Stream[bool][bool][source]¶ Computes the boolean stream of a string starting with a specific value.
Parameters: - s (Stream[str]) – A string stream.
- word (str) – A word that a string value can start with.
Returns: A boolean stream.
Return type: Stream[bool]
