Code Style. Python
Use this section to configure formatting options for Python files. When you change these settings, results of a change are displayed in the Preview pane.
Tabs and Indents
Use tab character
The Smart Tabs checkbox is available if the Use tab character checkbox is selected.
In this field, specify the number of spaces included in a tab.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted for each indent level.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted between the elements of an array, in expressions, method declarations and method calls.
Keep indents on empty lines
If this checkbox is selected, PyCharm will keep indents on the empty lines as if they contained some code.
Use this tab to specify where you want spaces in your code. To have PyCharm automatically insert a space at a location, select the checkbox 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, and so on) The right-hand pane shows preview.
Alignment takes precedence over indentation options.
Right Margin (columns)
Use the Hard wrap at field to specify a margin space required on the right side of an element. If you select Default option then a value of the right margin from the global settings is used.
Wrap on typing
Use the Wrap on typing settings to specify how the edited text is fitted in the specified Hard wrap at. You can select one the following options:
Default: in this case PyCharm uses the Wrap on typing option that is specified in the global settings.
Yes: in this case PyCharm uses the value specified in the Right Margin field.
No: in this case this option is switched off and a line can exceed the value specified in the right margin.
Use the Visual guides field to specify multiple right margins. You can leave a default value or enter the number of spaces for your margin. If you want to specify several margins, enter numbers separated by comma.
Keep when reformatting
Use the checkboxes to configure exceptions that PyCharm will make when reformatting the source code. For example, by default, the Line breaks checkbox is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks checkbox before you reformat the source code.
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.
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.
This table lists actions to be performed when imports are optimized.
Sort import statements
Select or clear this checkbox to enable or disable sorting imports within individual import groups according to PEP 8.
The following checkboxes affect the sorting order.
Structure of "from" imports
Leave as is
If this checkbox is selected, the "from" imports won't be restructured.
Join imports with the same source
If this checkbox is selected, the "from" imports of the same source are combined.
Always split imports
If this checkbox is selected, the "from" imports are always placed separately.
From the drop-down list, select the type of
Add line feed at the end of file
Select this checkbox to add line feed character at the end of file.
Use continuation indent for
Select the Method call argument checkbox to use continuation indent for list of arguments and the Collections and comprehensions checkbox for multi-line collection literals and comprehensions. The value of the continuation indent is defined in the Tabs and Indents tab. If these checkboxes are not selected, then the indent value is used.
