PEP 8 says:
Python accepts the control-L (i.e. ^L) form feed character as whitespace; Many tools treat these characters as page separators, so you may use them to separate pages of related sections of your file
This look like a great idea for me, but in the text editor I use(kate) "control+L" is for save all files. Someone have any solution?
... or I'm losing something here?
Ctrl-L simply refers to the character with ASCII code 12 (form feed, new page). It is called Ctrl-L only because some editors allow you to enter it with Ctrl-L. (For instance, in vim, one can type Ctrl-Q Ctrl-L to enter that character, and it also appears as ^L). In Kate, Ctrl-L is a shortcut for saving all files, so you cannot type it that way and I'm not sure there is any way of entering that character easily.
