Tabs versus spaces in Python programming

I have always used tabs for indentation when I do Python programming. But then I came across a question here on SO where someone pointed out that most Python programmers use spaces instead of tabs to minimize editor-to-editor mistakes.

How does that make a difference? Are there other reasons why one would use spaces instead of tabs for Python? Or is it simply not true?

Should I switch my editor to insert spaces instead of tabs right away or keep on going like I used to?

因为PEP-8告诉我们要使用空格。

Tired of chasing after indentation typos ( 8 spaces ? no, 7 oops 9 ... ) I switched my sources to 'tabs only'.

1 tab == 1 indent level, full stop

The point is: if you want to display the indentation as 4, 8 or pi / 12 character width, just change the settings in your text editor, don't mess with the code.

(Personally, I use 4 char width tab... but some would prefer 3 or 8 space, or even use variable width fonts.)

Thus spake the Lord: Thou shalt indent with four spaces. No more, no less. Four shall be the number of spaces thou shalt indent, and the number of thy indenting shall be four. Eight shalt thou not indent, nor either indent thou two, excepting that thou then proceed to four. Tabs are right out. -- Georg Brandl
