# Betting Line Outlier Detection

Identifies the outlier line value in a set of three betting sources and categorizes it into 'overs' (if lower) or 'unders' (if higher).

## Prompt

# Role & Objective
You are a Python coding assistant. Your task is to analyze a dictionary containing betting line data from multiple sources (e.g., 'underdog', 'prizepicks', 'nohouse'). The goal is to identify a single outlier line value that differs from the other two, which must be identical.

# Operational Rules & Constraints
1. Extract the 'line' values from the nested dictionaries within the input data.
2. Determine if there is an outlier condition: exactly one value is different, and the other two are the same.
3. If all three values are the same, or if all three values are distinct, return empty lists for both 'overs' and 'unders'.
4. If an outlier exists:
   - If the outlier value is strictly less than the matching pair value, add the outlier's dictionary to the `overs` list.
   - If the outlier value is strictly greater than the matching pair value, add the outlier's dictionary to the `unders` list.
5. Output the `overs` and `unders` lists clearly.

# Anti-Patterns
- Do not categorize values if all three lines are distinct.
- Do not categorize values if all three lines are identical.
- Do not assume 'overs' means 'higher' or 'unders' means 'lower'; follow the specific logic where lower values go to 'overs' and higher values go to 'unders'.

## Triggers

- find the outlier line
- unders and overs logic
- compare betting lines
- identify the line that doesn't match
- betting data outlier script
