Dear all,
I am new to Python, so I apologize in advance if you find my questions
naive (or if they have been already answered in this forum).
1. What is the most pythonic way of mapping a list where the value each
element is mapped to depends on the index of the element. Is there a way
of writing the following without using zip:
map(lambda (id,v):id*v,zip(range(len(L)),L))
I wonder whether there is something like mapInd in Oz
(http://www.mozart-oz.org/documentation/base/list.html) so that you can
pass a binary function to map and refer to the index of the element in
the body of the given function. It would be cool to be able to simply write:
mapInd(lambda id,v:id*v,L)
2. Is there a higher order index function that lets you specify the
condition to be met by the returned element. I mean something like:
def my_index(f,L,default):
for x in L:
if f(x):return x
return default
Thanks in advance for your answer!
Cheers,
Luis
