i have a question.

move the cursor.
for example,when i enter a string,i often enter the quotation mark ""
first,and the move the cursor inside the mark to enter the string,in
windows,it is ok.but when i do that in linux,pressing the "left" key
will just print "^[[D" in the screen ,but not what i want.

Python uses GNU readline for cursor movements. The Python version that ships
with your distribution should work out of the box. If you compile Python
yourself make sure that the development package (not just the binary) is
installed. For Suse this is readline-devel.

thanks for your reply
I thought maybe i just didn't install readline correctly,so i deleted
python and tried to re-compile the source code(I downloaded the .bz2
version).This time ,I found in the "./Modules/Setup" the description
for "readline":

# GNU readline. Unlike previous Python incarnations, GNU readline is
# now incorporated in an optional module, configured in the Setup
file
# instead of by a configure script switch. You may have to insert a
# -L option pointing to the directory where libreadline.* lives,
# and you may have to change -ltermcap to -ltermlib or perhaps remove
# it, depending on your system -- see the GNU readline instructions.
# It's okay for this to be a shared library, too.

#readline readline.c -lreadline -ltermcap

dont know exactly what to do,I just delete the "#" mark in the line
"#readline readline.c -lreadline -ltermcap " , then tried to
"configure","make",but errors of readline occor here.
what am i supposed to do to install the module GNU readline correctly
then?
thanks

Use the package manager of your distribution to install the readline
development package -- after some struggle with Mandriva's website I came
to suppose that it's libreadline5-devel for you:

urpmi libreadline5-devel.rpm

After you have successfully installed that package unpack the python archive
into a fresh directory and do the configure/make/install dance. No manual
changes should be necessary.
