Is this what you want?

pys = 'This string contains   two times   - end'
pyprint s.replace(' ', ' '*6)
This string contains two times - end


see http://docs.python.org/lib/string-methods.html

'abc def'

Also various modules that are meant to deal with web and xml and such
have functions to do such operations.

Oh, I didn't make myself clear.

What I mean is how to convert a piece of html to plain text bu keep as
much format as possible.

Such as convert "&nbsp;" to blank space and convert <brto "\r\n"

#!/usr/bin/env python
from HTMLParser import HTMLParser

parsedtext = ''

class Parser(HTMLParser):
def handle_starttag(self, tag, attrs):
if tag == 'br':
global parsedtext
parsedtext += '\\r\\n'

def handle_data(self, data):
global parsedtext
parsedtext += data

def handle_entityref(self, name):
if name == 'nbsp':
pass

x = Parser()
x.feed('An &nbsp; text<br>')
print parsedtext

&nbsp; corresponds to a non-breaking space, chr(160). if you're only
dealing with this specific XML/HTML entity, you can do

text = text.replace("&nbsp;", " ")

or

text = text.replace("&nbsp;", chr(160))

to handle arbitrary entities and character references, pass the data
through an HTML or XML parser, or use something like:

SE can also strip tags and translate all HTM escapes and generally lets
you do ad hoc translations in seconds. You just write them up, make an
SE object from your text an run your data through it. As simple as that.
If you wish further explanations, I'll be happy to explain.
