Best way to insert sorted in a list

Show all headers | View raw

There are basically two ways to go about this.
One is, to append the new value, and then sort the list.
Another is to traverse the list, and insert the new value at the
appropriate position.

The second one's complexity is O(N), while the first one's is O(N *
log N).

Still, the second one works much better, because C code is being used
instead of pythons.

Still, being a programmer, using the first way (a.insert(x);
a.sort()), does not feel right.

What has the community to say about this ? What is the best (fastest)
way to insert sorted in a list ?
