tabs

问题 Using a tab width of 4 spaces has emerged as the primary choice in programming. So why doesn't Python see a tab as 4 spaces instead of 8? Is there a (technical, historic, other) reason for this design decision?

问题 I have a workbook with many worksheets. I would like to see the tabs for all available worksheets at once, which will need more than one row of tabs at the bottom.

My thought is to use jQuery to trigger a click on the appropriate tab but it isn't working. var hash = window.location.hash; $(function() { $(window).on('load', function () { $(hash).trigger( "click" ); console.log(hash) }); }); The console.log shows the correct hash but the "click" doesn't appear to work. I would like to know any workarounds or

Adjusting tab_width for a TabbedPanelItem seems to have no effect, and as such the longer text is getting cut off. Example modified slightly from Kivy TabbedPanel docs, where I changed the first tab's heading to "Long Text for a Tab": from kivy.app import App from kivy.uix.tabbedpanel import TabbedPanel from kivy.lang import Builder Builder.load_string(""" <Test>: #size_hint: .5, .5 pos_hint:
