Apologies, I am completely new to Django and Python. I have 2 questions. First, how would I go about getting the last object created (or highest pk) in a list of objects? For example, I know that I could use the following to get the first object: list = List.objects.all()[0] Is there a way to get the length of List.objects? I've trie...

The problem is easy, I want to iterate over each element of the list and the next one in pairs (wrapping the last one with the first). I've thought about two unpythonic ways of doing it: def pairs(lst): n = len(lst) for i in range(n): yield lst[i],lst[(i+1)%n] and: def pairs(lst): return zip(lst,lst[1:]+[lst[0]])...

First I write the integer using python: out.write( struct.pack(">i", int(i)) ); I then read the integer using DataInputStream.readInt() in Java. I works but when it tries to read the number 10, and probably some other numbers too, it starts to read garbage. Reading the numbers: 0, 4, 5, 0, 5, 13, 10, 1, 5, 6 Java reads: 0, 4, 5, 0, 5, 1...

So, is there an undocumented wildcard character in strptime...
