file - Reading Freebase data dump in python, read to few lines? -


i trying use freebase data dump, seams have problems reading files python. looks program cant read lines.

def test2():     count=0     line in open(freebase_topic):         count+=1     return count  def test3():     count=0     line in open(freebase_quad):         count+=1     return count   if __name__ == "__main__":     print "freebase topic - nr lines:",test2()    print "freebase quad - nr lines:",test3()

results in this:

freebase topic - itr time: 1.21000003815 freebase topic - nr lines: 1643010  freebase quad - iter time: 0.797000169754 freebase quad - nr lines: 3155131

this can all. looks to few lines contain whole freebase. , cant see how possible iterate on 1 33gb file , 5gb file in 2 seconds.

what wrong? downloading files again in case went wrong during download process, takes decades connections, asking ere in mean time. file size correct, , have printed of lines , correct.

there problem occurred me:

open('file', 'rb')

should solve it.

chr(26)

sometimes causes file ending text mode 'r' default.
