Tabs and Indents
Use tab character
An indentation consists of two parts. One part results from nesting code blocks, and the other part is determined by alignment.
In this field, specify the number of spaces that fits 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 retains indents on empty lines as if they contained some code. If the checkbox is cleared, PyCharm deletes the tab characters and spaces on empty lines.
Indent chained methods
In declarations of functions, the second and further methods in a chain are displayed on a separate line.
Indent all chained calls in a group
The checkbox is available only when the Indent chained methods checkbox is selected.
Wrapping and BracesIn this tab, customize the exceptions, brace placement and alignment options that PyCharm will apply to various code constructs on reformatting the source code. Check the results in the Preview pane.
Hard wrap at
In this field, specify the number of spaces required to the right of an element. If you accept the Default option then the value from the global settings is used.
Wrap on typing
In this field, specify how the edited text is fitted in the specified Hard wrap at field.
In this field, 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 reformatting.
A wrapping style applies to various code constructs, specified in the left-hand pane (for example, method call arguments, or assignment statements).
Braces placement options
Use this tab to define where and how many blank lines you want PyCharm to retain and insert in your code after reformatting. The results are displayed in the Preview pane.
Keep Maximum Blank Lines
In this area, specify the number of extra blank lines to be kept after reformatting.
Minimum Blank Lines
In this area, configure whether to have or not to have extra empty lines after the blocks of
