Tabs and indents

Item Description
Use tab character
  • If this check box is selected, tab characters are used:
    • On pressing the TabTabTabTabTabTabTabTabTabTabTab key
    • For indentation
    • For code reformatting
  • When the check box is cleared, PyCharm uses spaces instead of tabs.
Smart tabs
  • If this check box is selected, PyCharm inserts tabs for indentation and reformatting, but fine alignment to a necessary column is done only via spaces without replacing them with tabs. This is done in order to preserve visual representation of the source code, when the Tab Size is changed.
  • If this check box is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment.

The Smart Tabs check box is available if the Use Tab Character check box is selected.

Tab size In this text box, specify the number of spaces included in a tab.
Indent In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.
Continuation indent In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted at the next line in case of a construct break.
Keep indents on empty lines If this check box is selected, then PyCharm will keep indents on the empty lines as if they have contained some code.
If this check box is not selected, PyCharm will delete the tabulation characters.
Detect and use existing file indents for editing Use this check box to detect code style settings in the currently edited file on the fly. In this case, when you open a file in the editor, indentation that was used in that file is preserved automatically. For example, if tabs were used for the indentation then in copy, paste or enter actions, tabs are used. Also, note that if you use the Reformat Code command then PyCharm applies default code style settings and uses them in the editor.

Spaces

Use this tab to specify where you want spaces in your code. To have PyCharm automatically insert a space at a location, select the check box next to this location in the list. The results are displayed in the Preview pane.

Wrapping and braces

In this tab, customize the code style options, which PyCharm will apply on reformatting the source code. The left-hand pane contains the list of exceptions (Keep when reformatting), and placement and alignment options for the various code constructs (lists, statements, operations, annotations, etc.). The right-hand pane shows preview.

Alignment takes precedence over indentation options.

Keep When Reformatting

Use the check boxes to configure exceptions that PyCharm will make when reformatting the source code. For example, by default, the Line brakes check box is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line brakes check box before you reformat the source code.

Blank lines

Use this tab to define where and how many blank lines you want PyCharm to retain and insert in your code after reformatting. For each type of location, specify the number of blank lines to be inserted. The results are displayed in the Preview pane.

Item Description
Keep Maximum Blank Lines In this area, specify the number of blank lines to be kept after reformatting in the specified locations.
Minimum Blank Lines In the text boxes in this area, specify the number of blank lines to be present in the specified locations.

Warning

These settings do not influence the number of blank lines before the first and after the last item.

Set From

Click this link to reveal the list of languages to be used as the base for the current language code style. So doing, only the settings that are applicable to the current language are taken. All the other settings are not affected.

This link appears in the upper-right corner of the language-specific code style page, when applicable.

Click Reset to discard changes and return to the initial set of code style settings.
