-# if-to-dict (SIM116)
-
-Derived from the **flake8-simplify** linter.
-
-Autofix is always available.
-
-### What it does
-Checks for three or more consecutive if-statements with direct returns
-
-### Why is this bad?
-These can be simplified by using a dictionary
-
-### Example
-```python
-if x = 1:
-    return "Hello"
-elif x = 2:
-    return "Goodbye"
-else:
-   return "Goodnight"
-```
-
-Use instead:
-```python
-return {1: "Hello", 2: "Goodbye"}.get(x, "Goodnight")
-```
