+# avoid-quote-escape (Q003)

+Derived from the **flake8-quotes** linter.
+
+Autofix is always available.
+
+### What it does
+Checks for strings that include escaped quotes, and suggests changing
+the quote style to avoid the need to escape them.
+
+### Why is this bad?
+It's preferable to avoid escaped quotes in strings. By changing the
+outer quote style, you can avoid escaping inner quotes.
+
+### Example
+```python
+foo = 'bar\'s'
+```
+
+Use instead:
+```python
+foo = "bar's"
+```

+Derived from the **flake8-quotes** linter.

+Autofix is always available.
+
+### What it does
+Checks for docstrings that use single quotes or double quotes, depending on the value of the [`docstring-quotes`](https://github.com/charliermarsh/ruff#docstring-quotes)
+setting.
+
+### Why is this bad?
+Consistency is good. Use either single or double quotes for docstring
+strings, but be consistent.
+
+### Example
+```python
+'''
+bar
+'''
+```
+
+Assuming `docstring-quotes` is set to `double`, use instead:
