    "##### `CounterfactualGenerator()` - Class for generating data for counterfactual discrimination assessment (class)\n",
    "\n",
    "**Class Attributes:**\n",
    "\n",
    "- `langchain_llm` (**langchain llm (Runnable), default=None**) A langchain llm object to get passed to LLMChain `llm` argument. \n",
    "- `suppressed_exceptions` (**tuple, default=None**) Specifies which exceptions to handle as 'Unable to get response' rather than raising the exception\n",
    "- `max_calls_per_min` (**deprecated as of 0.2.0**) Use LangChain's InMemoryRateLimiter instead.\n",
    "\n",
    "**Methods:**\n",
    "\n",
    "1. `parse_texts()` - Parses a list of texts for protected attribute words and names\n",

    "    - `system_prompt` - (**str, default=\"You are a helpful assistant.\"**) Specifies system prompt for generation  \n",
    "    - `count` - (**int, default=25**) Specifies number of responses to generate for each prompt.\n",

    "- `classifier` - (**{'vader','NLP API'}**) Specifies which sentiment classifier to use. Currently, only vader is offered. `NLP API` coming soon.\n",
    "- `sentiment` - (**{'neg','pos'}**) Specifies whether the classifier should predict positive or negative sentiment.\n",
    "- `parity` - (**{'strong','weak'}, default='strong'**) Indicates whether to calculate strong demographic parity using Wasserstein-1 distance on score distributions or weak demographic parity using binarized sentiment predictions. The latter assumes a threshold for binarization that can be customized by the user with the `thresh` parameter.\n",
    "- `thresh` - (**float between 0 and 1, default=0.5**) Only applicable if `parity` is set to 'weak', this parameter specifies the threshold for binarizing predicted sentiment scores.\n",
    "- `how` : (**{'mean','pairwise'}, default='mean'**) Specifies whether to return the mean cosine similarity over all counterfactual pairs or a list containing cosine distance for each pair. \n",
    "- `custom_classifier` - (**class object**) A user-defined class for sentiment classification that contains a `predict` method. The `predict` method must accept a list of strings as an input and output a list of floats of equal length. If provided, this takes precedence over `classifier`.\n",
