Most elegant way to modify elements of nested lists in place

Question

I have a 2D list that looks like this:

table = [[\'donkey\', \'2\', \'1\', \'0\'], [\'goat\', \'5\', \'3\', \'2\']]

I want to change the la

Answer 1

Try:

>>> for row in table:
...     row[1:]=map(int,row[1:])
... 
>>> table
[['donkey', 2, 1, 0], ['goat', 5, 3, 2]]

AFAIK, assigning to a list slice forces the operation to be done in place instead of creating a new list.
