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 current line. 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 view the full list of intentions and customize them in the Settings/Preferences dialog Ctrl+Alt+S.
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. Quick-fixes and intention actions together are called context actions.
Apply intention actions
Click the bulb icon (or press Alt+Enter) to open the list of suggestions and select an action from the list.
For some intention actions, you can open a preview by pressing Ctrl+Shift+I().
For example, PyCharm provides an intention that converts

The way f-string literals appear in the Editor depends on the corresponding Color Scheme settings. In the Settings/Preferences dialog Ctrl+Alt+S, navigate to , select in the list of components, and modify the available settings if needed.
