Hi there,
I'm configuring a python command to be used by emacs to filter a
buffer through python markdown, and noticed something strange. If I
run this command in the terminal:
python -c "import sys,markdown; print
markdown.markdown(sys.stdin.read().decode('utf-8'))" <
markdown_source.m
if 'ar' or 'ko' in item:
This is incorrect. What you meant to say was:
if 'ar' in item or 'ko' in item:
or something equivalent to that.
"if 'ar' or 'ko' in item" means "if ('ar') is True or ('ko' in item) is
True". Since 'ar' is True anyway, you'll get a match every time.

More thoughts on converting VFP to Python:
line-by-line can take into account control structures. One just
increases or decreases the indent when encountering the start or end of
a structure.
a bigger challenge is handling the work-area related commands such as
Scan, Replace, Skip, Set Relat

Thanks for all the replies. Yes that was actually what I meant. My

Hi John!
I have written a (currently mostly defunct) compiler in Python for a
specialized programming language. The parser may serve as an example
for you.

The interpreter sees this as
if ('arr') or ('bell' in item):
'arr' always evaluates to True so the condition is always true. The
correct way to express this condition is
if 'arr' in item or 'bell' in item:

Hi John,

eduardo,
welcome to programming, and even better, welcome to Python! you've
done your research and found a list of great people who can help you
out.
with regards to your question, my comment are below...

I tried what Bill Campbell suggested: read the len first and then use that
to populate the structdef length field for the string
len = xstruct.structdef(xstruct.little_endian, [
('len', (xstruct. unsigned_long, 1)),
])
l = len(buf[0:3])
rec = xstruct.structdef(xstruct.little_endian, [
#! /usr/bin/python
list1 = ['arr', 'bre', 'grau', 'lower', 'tudo']
for item in list1:
if item == 'arr' or item == 'grau':
print list1
Hopefully, my rewording of one of your tests will make it a bit easier
to see what is happening.
A for statement such as 'for item in list

Hello, I'm trying to teach my self programming with python and there
are some basic things that stumps me:
Given this code:
###
list1 = ['arr', 'bre', 'grau', 'lower', 'tudo']
for item in list1:
if 'arr' in item:
print list1
###
The output is (as expected):
['arr', 'bre', 'grau', 'lower

Unless you're keen on writing your own html/css/javascript/etc rendering
