#### Documentation problem

GL01 pandas docstring errors. `Docstring text (summary) should start in the line immediately after the opening quotes (not in the same line, or leaving a blank line in between.`

#### Suggested fix for documentation


It's really unnecessary using `\` to break the line when using `"""` as the docstring. It also treats the next line as the same line. Remove the `\` instead.
