pypy

I am trying to complete an uncomplete list of numbers, I couldn't find any pythonic way to do it. I have a sequence of days from 1 to 31, and for each day, I have a float value. #dictionnary{day: value} monthvalues = {1: 1.12, 2: 3.24, 3: 2.23, 5: 2.10, 7: 4.97} etc.. to 31st day but my data is uncomplete, and some days are missing! therefore I want to fill the missing picture mathematically this way: sample month1: {16: 2.00, 18: 4.00} #==> I want to add to the dictionnary 17: 3.00 sample month2: {10: 2.00, 14: 4.00} #==> I want to add to the dictionnary 11: 2.25, 12: 2.50, 13: 2.75 sounds

I'm currently trying to use pypy but unfortunately unable to use pip the python package manager. I added the following mirror to my source.list: deb http://ftp.de.debian.org/debian jessie main I installed then the pypy package using apt-get: apt-get install pypy Then I followed the steps given by the pypy documentation to install pip : curl -O http://python-distribute.org/distribute_setup.py curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py pypy distribute_setup.py pypy get-pip.py but i'm unable to find the pip executable for pypy. The only trace of pip for pypy is this one :

I'm trying to embed a Python function in C using PyPy and cffi. I'm following this guide from the PyPy documentation. The problem is, all the examples I've found operate on ints, and my function takes a string and returns a string. I can't seem to figure out how to embed this function in C, as C doesn't seem to really have strings, rather making do with arrays of chars. Here's what I've tried: # interface.py import cffi ffi = cffi.FFI() ffi.cdef(''' struct API { char (*generate_cool_page)(char url[]); }; ''') ... @ffi.callback("char[] (char[])") def generate_cool_page(url): # do some

I'm currently working through the problems on Project Euler, and so far I've come up with this code for a problem. from itertools import combinations import time def findanums(n): l = [] for i in range(1, n + 1): s = [] for j in range(1, i): if i % j == 0: s.append(j) if sum(s) > i: l.append(i) return l start = time.time() #start time limit = 28123 anums = findanums(limit + 1) #abundant numbers (1..limit) print "done finding abundants", time.time() - start pairs = combinations(anums, 2) print "done finding combinations", time.time() - start sums = map(lambda x: x[0]+x[1], pairs) print "done
