Thanks for your reply. I understand this fact, but I wonder why
writelines() works slowly -- I think C code can be optimised to work
faster than Python one. Is it correct that writelines(...) is just a
shorthand for
for ch in ...:
file.write(ch)
?

the first copies all the substring to a single string large enough to
hold all the data, before handing it over to the file object, while the
second just writes the substring
My question is: why write(''.join(...)) works slowly than
writelines(...)? Here's the code:
import sys
import random
#try:
#import psyco
#psyco.full()
#except ImportError:
#pass
def encrypt(key, infile, outfile, bufsize=65536):
random.seed(key)
in_buf = infile.read(bufsize)
