How to remove extension from the filenames from a list of filenames in Python?

I am trying to rename all the items in the list by removing the '.csv' extension from each item

The following code removes the extension in the variable new but does not replace each with new:

csv = ['NC_hello1.csv', 'NC_hell02001.csv', 'NC_hello20002.csv']
for each in csv:
     new = os.path.splitext(each)[0]
     each = new
     print each

How do I get the following output?

NC_hello1
NC_hell02001
NC_hello20002

Try something like this:

csv = [os.path.splitext(each)[0] for each in csv]

Alternatively, if you need to further process the modified filename, e.g. print it like in the code above, access the list by indexing its elements:

for index,each in enumerate(csv):
    new = os.path.splitext(each)[0]
    csv[index] = new
    print new
