Re: [Tutor] Best way to replace items in a list.

[Jason Massey]

You can access and change the elements in a list by directly referencing their position in the list.

Something like:

>>> foo = [1,2,3]
>>> foo[0]
1
>>> foo[0] = 'a'
>>> foo
['a', 2, 3]

Will that replace the location? or add to it?

Thanks.

Why not:

if item in list:
 loc = list.index(item)
 list[loc] = str

I'm trying to build a little piece of code that replaces an item in a list.

Here is a sample of what I'd like to do.

str = "This was replaced"

ff item in list:
   replace item with str

I know I can do list.remove(item), but how do I place str back into that exact location?

Is this how / best way?

if item in list:
   loc = list.index(item)
   list.remove(item)
   list.insert(loc, str)

Thanks.
