Any code completion or live template operation ends up with a suggestion list, from which you have to select the desired option. PyCharm provides handy ways to make your selection, complete the source code, sort entries, and view reference information without leaving the suggestion list.
In this section, you will learn:
- To navigate though the suggestion list and completed expression
- To complete selection
- To view reference information in the suggestion list
- To sort entries in the suggestion list
- To view hierarchy in the completion pop-up
- To close the suggestion list
- Use the mouse cursor or the UpUpUpUpUp or Ctrl+PUpUpUpUp or Control PUpUp or Control P and DownDownDownDownDown or Ctrl+NDownDownDownDown or Control NDownDown or Control N arrow keys to navigate through the suggestion list.
Use the horizontal arrow keys in the completed expression to make the suggestion list wider (left arrow) or closer (right arrow):
- Use EnterEnterEnterEnterEnterEnterEnterEnterEnterEnterEnter to insert the selected string at the insertion point.
- Use TabTabTabTabTabTabTabTabTabTabTab to replace the string next to the caret with the selected one.
- Use Ctrl+Shift+EnterCtrl+Shift+EnterCtrl+Shift+EnterCtrl+Shift+EnterCtrl+Shift+EnterCtrl+Shift+EnterCtrl+Shift+EnterCtrl+Shift+EnterShift Command EnterShift Command EnterShift Command Enter to make the current code construct syntactically correct (balance parentheses, add missing braces and semicolons, etc.)
- It is possible to enter the desired element name manually when the input position is highlighted and
the list of suggestions is open. As you type, the suggestion list shrinks so that only matching
element names remain:
If you enter a name that is not used in the scope, PyCharm will inform you with a pop-up window as shown in the figure below:

- If, invoking an action, you don’t get what you want immediately, invoke this action again by pressing the same shortcut.
- Most suitable variants in the suggestion list are displayed on the green background on top of the list.
