Jython

[Boris Ozegovic]

Hi

Why this doesn't work:

def go():
for line in open("bobo.txt" , "r"):
print line

go()

python FileReader.py: everything ok
jython FileReader.py:

Traceback (innermost last):
File "FileReader.py" , line 6
File "FileReader.py" , line 3
AttributeError: __getitem__

Files aren't lists and thus don't have the functions for iteration.

Try:

def go():
for line in open("bobo.txt" , "r").readlines( ):
print line

go()

They do have iterator:

C:\Documents and Settings\Silova na Vjeverica\Deskt op>python FileReader.py
'import site' failed; use -v for traceback

But apparently not in Jython... Only Python.

Tnx, anyway

For example, you can do even this:

import sys

for line in sys.stdin:
print line,


python FileReader.py < bobo.tx

'import site' failed; use -v for traceback

Iterable files were introduced in Python 2.2. Jython implements Python2.1,
it seems.

CPython 2.1 has xreadlines, maybe Jython has it too.
