python character map range

I have the basics for making the character map but I cant seem to get the range to work...

I keep on getting some weird int or str error no matter what I try.

There are 2 files. The first is an html file that acts as a form. The second is the .py program

Can someone help me figure out how to get the program to have the range that was inputted from file 1 appear onto file 2? And, I want to have a limit to that range...that is even if someone typed in 400-900, i want just 400-500 to appear.

All you have to do is convert file 1 into html and file 2 into .py

The range that i had is not in the .py file because it keeps on having errors...

for i in range (int(["start"],["end"]))
print unichr(i)

I haven't tested it but something like this?

Code:

end = int(form["end"].value)
if end > 500: 
    end = 500
char = int(form["start"].value)
while char <= end: 
    print '<tr>'
    print '<td class="num">'+str(char)+'</td>'
    print '<td><code class="html">&#%03d;</code></td>'%(char, )
    print '<td class="char"><span>&#%03d;</span></td>'%(char, )
    print '<td class="name">%s</td>'%(unicodedata.name(unichr(char)), )
    print '</tr>'
    char = char+1
print '</tbody>'

Another untested code snippet using a for loop and range() this time (based on grims code).

Code:

print '<table>'

start = int(form['start'].value)
end = int(form['end'].value)

for each in range(start, end):
    print '<tr>'
    print '<td class="num">%s</td>' % each
    print '<td class="html">&#%03d;</td>' % each
    print '<td class="char">&#%03d;</td>' % each
    print '<td class="name">%s</td>' % unicodedata.name(unichr(each))
    print '</tr>'
    
    if each == 500:
        break
    
print '</table>'

Hope this is of some help,

Mark.

what if i wanted to have a limit of just 100 characters appearing even when someone asks for 300? I didn't mean that the characters only goes up to #100

Something like:

Code:

if end - char >100:
    end = char+100

Surly you would just alter the limit?I could be being really dumb though

Code:

print '<table>'

limit = 100

start = int(form['start'].value)
end = int(form['end'].value)

for each in xrange(start, end):
    print '<tr>'
    print '<td class="num">%s</td>' % each
    print '<td class="html">&#%03d;</td>' % each
    print '<td class="char">&#%03d;</td>' % each
    print '<td class="name">%s</td>' % unicodedata.name(unichr(each))
    print '</tr>'
    
    if each == limit:
        break
    
print '</table>'

Or in grims example (just to show Grims code snippet in context)...

Code:

end = int(form["end"].value)
char = int(form["start"].value)
if end - char > 100: 
    end = char + 100
while char <= end: 
    print '<tr>'
    print '<td class="num">'+str(char)+'</td>'
    print '<td><code class="html">&#%03d;</code></td>'%(char, )
    print '<td class="char"><span>&#%03d;</span></td>'%(char, )
    print '<td class="name">%s</td>'%(unicodedata.name(unichr(char)), )
    print '</tr>'
    char = char+1
print '</tbody>'

In both these examples the char range cant exceed the set limit (100).

note: still untested

edit: changed range() to xrange(), this makes little difference to the current example but with huge numbers it saves Python from creating a new list in memory (which can lead to memory errors in very extream cases).

How do you mean an error? Pythons giving you an error message or are the characters just not showing right? If its the latter i'd guess its because those numbers dont have any related characters i.e.

Code:

>>> for each in range(100):
...     print chr(each),
...     
         	

                    ! " # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ] ^ _ ` a b c
>>>

Note: If you have wxPython try running that in the PyShell and it will replace the boxes by there char's. In IDLE you'll get the boxes as above.

in python it works great.....but when I put it on the web...

First character 0
Last character 200

there will be an error instead of having just the 32-132 characters appearing

I tried using something like:

name=unicodedata.name(unichr(char), "undefined")
if name!="undefined":

but it just crashes the page lol

Mmmm, i'm a little unsure as to whats going on. Do you have an example i could mabe look at? Also, if you have access to the server maybe you could tell me what errors your getting in your error log.

But maybe i should download the two files that i seem to have over looked

Anyway its late, night all.
