Hi, all. I'm not sure if this is a bug report, a feature request or what, so I'm posting it here first to see what people make of it. I was copying over a large number of files using shutil, and I noticed that the final files were taking up a lot more space than the originals; a bit more investig

Hi Nico, it's converting fill==True to an int, thereby choosing the string "False," or "True," by indexing into the tuple. Try this in an interpreter: >>> ['a','b'][False] 'a' >>> ['a','b'][True] 'b' >>> int(False) 0 >>> int(True) 1 Joost On 29 September 2010 12:42, Tracubik wrote: > > Hi all,

This is just a sneaky shorthand, which is fine if that's what you want, but it makes it harder to read. The reason it works is that 'fill==True' is a boolean expression, which evaluates to True or False, but if you force a True into being an integer, it will be 1, and a False will become 0. Try w
