Yes they will be cached. But do yourself a favour and check out the string methods. E.g. >>> import re >>> def opfunc(s, spaces): ... s=re.sub(r'\n','\n'+spaces,s) ... s=re.sub(r'^',spaces,s) ... s=re.sub(r' *\n','\n',s) ... s=re.sub(r' *$','',s) ... s=re.sub(r'\n*$','',s) ... return s ... >>> def myfunc(s, spaces): ... return '\n'.join(spaces + x.rstrip() if x.rstrip() else '' for x in s.splitlines()) ... >>> t1 = 'foo\nbar\nzot\n' >>> t2 = 'foo\nbar \nzot\n' >>> t3 = 'foo\n\nzot\n' >>> [opfunc(s, ' ') for s in (t1, t2, t3)] [' foo\n bar\n zot', ' foo\n bar\n zot', ' foo\n\n zot'] >>> [myfunc(s, ' ') for s in (t1, t2, t3)] [' foo\n bar\n zot', ' foo\n bar\n zot', ' foo\n\n zot'] >>> -- http://mail.python.org/mailman/listinfo/python-list
