Quality Code

Here is some quality code Alex Martelli posted on comp.lang.python;

class fifo:
    def __init__(self):
        self.data = []
        self.first = 0
    def head(self):
        return self.data[self.first]
    def pop(self):
        self.first += 1
        if self.first > len(self.data)/2:
            self.data = self.data[self.first:]
            self.first = 0
    def append(self, value):
        self.data.append(value)

I'm posting it here as a mental note to myself to use this class whenever I need a first in, first out stack.
