i use python 2.5. os is window 7.
the puzzle is :python don't read the leave text when meet character:
chr(26)
the code is:
/fileObject=open('d:\\temp\\1.txt','w')
fileObject.write('22222222222222\r\n')
fileObject.write(chr(26)+'\r\n')
fileObject.write('33333333333333')
fileObject.close()
fileObject=open('d:\\temp\\1.txt','r')
i=0
for line in fileObject:
i+=1
print str(i)+'******'+line
fileObject.close()/
the output only print:
/>>>
1******22222222222222/
but can't print next line text:/'33333333333333'' 。who tell me why?

chr(26) can sometimes be used in text files to indicate the end of the text.
In Microsoft Windows it dates from MS-DOS, which borrowed from CP/M, an
operating
system which stored the file size as the number of 128-byte records.
chr(26) was used to
indicate where the text ended in the last record.
On Win a ctrl-z is end of file. So if you want to read beyond the end
of a text file, you have to pretend it's binary. Open it with "rb"
instead of "r"
