Ok, I proabably haven't been clear enough. Here is what I really want to
do: I have a list of strings ( the content of strings are actually
numbers ), for example I have the following list: ['4312', '7599',
'0724', '0003']. The things I need to do is to change the strings inside
the list to integers and then write the list to a file ( I know how to do
the latter:). The problem is, if I change it with
int(my_string_inside_the_list) I won't get the same numbers, and I need
to have the content of the string and integer the same. So, after the
conversion of that list, what I want to have is: [4312, 7599, 0724, 0003]
and NOT [4312, 7599, 724, 3].
Can you solve my problem?
Your help will be appreciated.
Thank you
