cStringIO versus StringIO: "readlines"
by Brian Kelley Nov. 2, 1999

Nov. 2, 1999

I noticed that StringIO has a "readlines" member function and cStringIO doesn't. Is anyone planning on adding this in the near future? I was wondering if I should go ahead and do it or if there is against. The cStringIO documentation just says "provides an interface similar to StringIO" and StringIO says "see the description on file objects." Needless to say, I use readlines() quite a bit. -- Brian Kelley w 505 995-8188 Bioreason, Inc f 505 995-8186 309 Johnson Av Santa Fe, NM 87501 kelley(a)bioreason.com

Does Python use standard optimisation techniques on that byte code (CSE, strength reduction, and all that)? I would be tempted to guess that the stack machine receives code that pretty closely resemble the source code. Would the stack machine be able to express optimisations? For example, could we copy or exchange arbitrary stack elements? If yes, maybe one could attempt filtering a `.pyc' through an optimiser, at least for a long experimental phase, with the hope of having the optimiser integrated right into Python, one of these later days. If no, would Guido be favourable at opening the door by adding a few more stack machine instructions, even if not using them himself, to start with? -- François Pinard http://www.iro.umontreal.ca/~pinard

Printing strings
by Matthew Hirsch Nov. 2, 1999

Nov. 2, 1999

Hi All, I'm trying to do something like the following: a=4.0 b=2.0 print '2(%3.1f)' % a,b where I really mean print '%3.1f %3.1f' % a,b but it's printing 2(4.0) 2.0 Is there a way of doing this so I don't have to write out %3.1f, multiple times? Thanks, Matt

Tkinter canvas blow-up: bbox(ALL) == None
by Randall Hopper Nov. 2, 1999

Nov. 2, 1999

Apparently if the bounds of the items in a Tk canvas widget exceed MAXINT, bbox(ALL) returns None. The attached Python script demonstrates this. Intuitively it seems like this is a bug since the contents of the canvas are maintained in floating point; integer bounds shouldn't be involved, should they? Is this a Tk bug or a Tkinter bug? Thanks, Randall -- Randall Hopper aa8vb(a)yahoo.com
