I have this string:
mystring = 'Here is some text I wrote '
How can I substitute the double, triple (...) whitespace chracters with a single space, so that I get:
mystring = 'Here is some text I wrote'
A simple possibility (if you'd rather avoid REs) is
' '.join(mystring.split())
The split and join perform the task you're explicitly asking about -- plus, they also do the extra one that you don't talk about but is seen in your example, removing trailing spaces;-).
