Well, your original post only asked /how/ to search for one of
those characters ("Can someone tell me how?"), but failed to
specify /what/ you wanted to do with the results.
If you wanted the index of the first one, then
results.start()
will return that.
If you want the character in that set that was found first, it is
found in
results.group(0)
Or, if you want them all, you can use
r.findall(a_string)
which will return a list of all the characters in that set that
were found in a_string.
Using the interpreter's built-in help and introspection can be
immensely helpful, as you can do things like
>>> dir(results) # to find what you can do with the results
>>> dir(r)# find out what a compiled regex object can do
>>> help(results.start) # learn about the start() function
Just a few pointers,
