Sorry for my blunder earlier, I'll try to make it up.

It looks like Python does not provide syntax folding. As Tim suggests, "indent" folding is normally recommended since Python indentation is semantic.

I have no idea who may ever want indentation folding. Usually in any case indentation matters indented code looks like

    start of block

        indented block

    [end of block]

and you want `start of block` be folded with indented block and displayed in a fold text because it is usually a block header. *Not* just fold out the indented block and display rather meaningless first line of indented block. And also include end of block as well if it is there.

Things become more complicated if `start of block` spans on multiple lines, but simple indentation folding is not convenient here as well because it can partly fold `start of block`.

 

But others have tried making plugins for better folding, I don't know how good they are (and there may be more, these are from http://vim.wikia.com/wiki/Syntax_folding_of_Python_files#Plugins):

If you write your own, you probably can use the indent() function to use the indentation of a line, except for in certain circumstances which you define. Take a look at :help fold-expr for how to write a function that defines the folding, then do a :setl foldmethod=expr foldexpr=MyPythonFoldFunction() to use it.
