Some years ago, I added a script for updating headers for (C) in the python files I was developing for Risu.
In this way, the header got the list of authors and years working on the files updated automatically.
With the pass of the years, the list started to became a bit too long, so I worked on creating code for getting ranges instead.
This is the code I used:
def getranges(data): """ From list of strings representing numbers, get ranges and return list of strings :param data: list of strings representing numbers :return: list of strings with number ranges when > 1 """ # Convert to integers data = [int(i) for i in data] result = [] if not data: return result # Prepare iteration loop idata = iter(data) first = prev = next(idata) first = first prev = prev # Process next item for following in idata: if following - prev == 1: # Years are continuum, just update previous prev = following else: # Years are not continuum, end range and start again if first == prev: result.append(first) else: if first + 1 == prev: # Only one item in difference, append items individually result.append(first) result.append(prev) else: result.append("%s-%s" % (first, prev)) first = prev = following # Catchall for regular execution or last remaining range if first == prev: result.append(first) else: if first + 1 == prev: # Only one item in difference, append items individually result.append(first) result.append(prev) else: result.append("%s-%s" % (first, prev)) # Convert back to text result = [str(i) for i in result] return result With it, previous headers like:
