problem with exec

Hello,

After my program read and translate this code:

koristi os,sys;
ispisi 'bok kaj ima';

into the:

import os,sys;
print 'bok kaj ima';

and when it run this code with "exec", I always get error like this, but I
still dont't know what is a problem:

Traceback (most recent call last):
File "C:\Python24\Lib\site-packages\VL\__init__.py", line 188, in
kompajlati
kompajlati_proces()
File "C:\Python24\Lib\site-packages\VL\__init__.py", line 183, in
kompajlati_proces
h2=Konzola()
File "C:\Python24\Lib\site-packages\VL\__init__.py", line 158, in __init__
k=kod(ZTextCtrl.GetLabel())
File "C:\Python24\Lib\site-packages\VL\__init__.py", line 83, in kod
exec(str_ngh)
File "<string>", line 1
import os ,sys ;
^
SyntaxError: invalid syntax

PS: How can I change when user write script with my program to he don't need
aspirate the lines of his source code
e.g.
import os,sys
n=90
if n==90:print "OK"
else:print "No"
Regards,

Vedran

I'm afraid I don't understand this question. If you are talking about
the indentation of the code, if you don't want indentation you will have
to use braces - { and } - to indicate the nesting structure of your program.

Oh my, teasing the n00bs like that is not nice. You know Python doesn't
uses braces, it uses BEGIN ... END blocks.

Hello,

Thanks for everything previously, but just to I ask about code
indentation,this with { and } doesn't
employed, here is my example how can I solve this about code
indentation:
>>n=90
if n==90:
{print "bok kjai ma'}
File "<input>", line 2
{print "bok kjai ma'}
^
SyntaxError: invalid syntax
Thanks!!!!!!!

Regards,Vedran

Steve Holden was playing silly games. You can't use { } for indentation.
You have to use indentation.

I wasn't playing silly games at all, and I did prefix that part ofmy
answer with "I'm afraid I don't understand this question". The OP is
writing a program to "translate" a Python-like language that uses
non-English keywords into Python. Since the application is transforming
its input, it could transform braces into indentation. Of course
*Python* doesn't use braces, but the question was how to write
"pseudo-Python" without using indentation to indicate grouping.

Steve

If you are using the tokenize module as suggested some time ago, try to
analyze the token sequence you get using { } (or perhaps begin/end pairs
in your own language, that are easier to distinguish from a dictionary
display) and the sequence you get from the "real" python code. Then write
a script to transform one into another:

from tokenize import generate_tokens
from token import tok_name
from cStringIO import StringIO

def analyze(source):
g = generate_tokens(StringIO(source).readline)
for toknum, tokval, _, _, _ in g:
print tok_name[toknum], repr(tokval)

I think you basically will have to ignore INDENT, DEDENT, and replace
NAME+"begin" with INDENT, NAME+"end" with DEDENT.
