I'm writing a Scheme interpreter and I need to be able to create and return
a Python function from a string.
This is a port of another Scheme interpreter I wrote in Scheme. What I'm
trying to do looked like this:
(define (scheme-syntax expr)
(hash-table-set! global-syntax (car expr) (eval (cad

To update the numbers list you would want something like this:
numbers = [1, 2, 3, 4, 5]
for n in range(len(numbers)):
numbers[n] += 5
print numbers
Alternatively if you didn't need to update the numbers list you could make a
new list like this:
[n
save a data structure like an array (called a list in Python), you can
use the pickle module. Here's the documentation on pickle.

You need to remove the quotes from f. f is a variable name, not a string,
so there should be no quotes around it.

27;s an example I just ran...
>>> import os
>>> os.getcwd()
'/media/DATA/code/lispy/liSpy'
The folder that is returned from os.getcwd() is the folder that "open" will
use. You can specify another folder by giving the full path.
open("/full/path/to/file.txt

I'm wondering if there's an easy way to do a 'svn commit' on a
directory from Python.
More Details:
I have a wiki-like program that stores its data in a directory that I
would like to put under version control to be able to roll back
unwanted changes. The program is stored in two directories, a '

thon can run Python code in two modes, interpreted or compiled. In the
latter case, the Lisp code is translated into assembly. The advantage of
interpreted code is that debugging is easier (the stack trace contains more
information); on the other hand execution of compiled code is much faster.

modifying the program to watch for certain keywords which will enable the

important. Afterall how exciting would life be if you couldn't sneak a peek

make the program start for any user that logs on?
