And if you prefer not to type so much:
def I(*args): return "".join(map(str, args))
def F(v, fmt): return ("%" + fmt) % v
Not that I don't appreciate the suggestions from masters of the Python
universe, but the reason I'm switching to Python from Perl is for the
readability. What you fells are suggesting might as well be riddled
with dollar signs and semicolons... <emoticon>.
Really what I was trying to showing you was that you could use eval and
do arbitrary expressions using sneaky slicing.
v[1::2] is every odd position, and it can be used for replacement.
v[1::2] = [str(eval(txt)) for txt in v[1::2]]
Is likely what you want; it got ugly when I lifted it into a function.
The cute trick is to use a quote delimiter and observe that the odd
positions are the quoted text.
