# ConditionStep **`class ConditionStep(config)`** Bases: [`BatchedStep`](../technical/libnlp/steps/standard.md#squirro.lib.nlp.steps.batched_step.BatchedStep) Step that executes other steps based on provided condition. Parameters - `step` ([`str`](https://docs.python.org/3.11/library/stdtypes.html#str)) – flow - `type` ([`str`](https://docs.python.org/3.11/library/stdtypes.html#str)) – condition - `condition` ([`dict`](https://docs.python.org/3.11/library/stdtypes.html#dict)) – Condition based on which the step to be executed is selected. If declared condition passed, the step defined in the “true_step” key is executed, otherwise the step from the “false_step” key is chosen. Available conditions: healthy_service, healthy_nlp_service, truthy_server_config. - `true_step` ([`dict`](https://docs.python.org/3.11/library/stdtypes.html#dict)) – Step configuration that should be executed when condition is true. - `false_step` ([`dict`](https://docs.python.org/3.11/library/stdtypes.html#dict)) – Step configuration that should be executed when condition is false. **Example** ```json { "step": "flow", "type": "condition", "condition": { "truthy_server_config": { "key": "topic.test-key" } }, "true_step": { "step": "external", "type": "remote_spacy", "name": "remote_spacy", "field_mapping": { "user_terms_str": "nlp" }, "disable_pipes__default": ["merge_noun_chunks"] }, "false_step": { "step": "app", "type": "query_processing", "name": "custom_spacy_normalizer", "model_cache_expiration": 345600, "infix_split_hyphen": false, "infix_split_chars": ":<>=", "merge_noun_chunks": false, "merge_phrases": true, "merge_entities": true, "fallback_language": "en", "exclude_spacy_pipes": [], "spacy_model_mapping": { "en": "en_core_web_sm", "de": "de_core_news_sm" } } } ``` Methods SummaryMethods Documentation **`choose_step_config()`** Return type [`dict`](https://docs.python.org/3.11/library/stdtypes.html#dict) **`is_condition_true(**kwargs)`** **`process_batch(batch)`** Process a batch of documents. If not defined will default to using self.process_doc for each document in the batch.
