Hi,

The example looks like you need the third
characater of the string:
print "3579"[2] # zero based

you can use int() to make it an integer
and str() to make an integer a string.

Or you want to search in the string for e.g. "5":

mystring="12345"
idx=mystring.find("3")
if idx==-1:
    print "not found"
else:
    print "Found it at index %s" % idx


HTH,
