Hi, During my Python (3.1) programming I often find myself having to repeat code such as... class1.attr1 = 1 class1.attr2 = 2 class1.attr3 = 3 class1.attr4 = 4 etc. Is there any way to achieve the same result without having to repeat the class1 prefix? Before Python my previous main language was Visua... 23 Apr 2010 20:49

default value in list comprehension
Hi, just a quick one, Is it possible to achieve a default value in a list comprehension where the if-clause is false? Ie, something similar to: [ a for a in b if something(a) else 'default' ] the idea being that, rather than skip a value if the if-clause is false, to place a default value at that posit... 20 Apr 2010 15:49

It should be 192 bytes long, but I know the 3rd through 6th byte are null chars and the array was truncated right before byte 3. Is there any way to... 20 Apr 2010 15:49
