You can simulate it fairly easily, but it will internally read the
file line by line and will take the time roughly proportional to the
size of the file.
from itertools import islice
def seek_to_line(f, n):
for ignored_line in islice(f, n - 1):
pass # skip n-1 lines
f = open('foo')
seek_to_line(f, 9000) # seek to line 9000
# print lines 9000 and later
for line in f:
print line
