# Open a file in binary (b) mode for writing.
fp = open("mybinaryfile", "wb")
# Write whatever data you like to it.
fp.write('\0'*1000000)
fp.close()


That writes one million ASCII NULL bytes to the file. If you prefer 
binary megabytes instead of decimal megabytes, use 1024*1024 instead of 
one million.

If you want some other binary data, you'll have to tell us what binary 
data you want to write.
