[python] pycharm convert tabs to spaces automatically

I am using pycharm IDE for python development it works perfectly fine for django code so suspected that converting tabs to spaces is default behaviour, however in python IDE is giving errors everywhere because it can't convert tabs to spaces automatically is there a way to achieve this.

ctr+alt+shift+L -> reformat whole file :)

PyCharm 2019.1

If you want to change the general settings:

Open preferences, in macOS ?; or in Windows/Linux Ctrl + Alt + S.

Go to Editor -> Code Style -> Python, and if you want to follow PEP-8, choose Tab size: 4, Indent: 4, and Continuation indent: 8 as shown below:

Apply the changes, and click on OK.

If you want to apply the changes just to the current file

Option 1: You can choose in the navigation bar: Edit -> Convert Indent -> To Spaces. (see image below)

Option 2: You can execute "To Spaces" action by running the Find Action shortcut: ??A on macOS or ctrl?A on Windows/Linux. Then type "To Spaces", and run the action as shown in the image below.

For me it was having a file called ~/.editorconfig that was overriding my tab settings. I removed that (surely that will bite me again someday) but it fixed my pycharm issue

For selections, you can also convert the selection using the "To spaces" function. I usually just use it via the ctrl-shift-A then find "To Spaces" from there.

ctrl + shift + A => open pop window to select options, select to spaces to convert all tabs as space, or to tab to convert all spaces as tab.

This only converts the tabs without changing anything else:

Edit -> Convert Indents -> To Spaces

Just ot note: Pycharm's to spaces function only works on indent tabs at the beginning of a line, not interstitial tabs within a line of text. for example, when you are trying to format columns in monospaced text.
