Intention actions
As you work in the editor, PyCharm analyzes your code, searches for ways to optimize it, and detects potential and actual problems.
As soon as the IDE finds a way to alter your code, it displays a yellow bulb icon in the editor next to the cursor. By clicking this icon, you can view intention actions available for this unit of code. Intention actions cover a wide range of situations from warnings to optimization suggestions. You can open the full list of actions, view their descriptions, and disable intentions in the settings.
A red bulb with an exclamation mark indicates that PyCharm has detected a problem, and prompts you to select an associated fix — a quick-fix.
