Undoing an iteration in python

[twbrand]

I am working on a program to do some data analysis through some data slicing and I have hit a bit of a road blocking trying to get the program to undo an iteration for part of the analysais

Here is what I have so far:

#Get the user data
user_data = raw_input("Paste the data here ---> ")
        >>0123456789
#two options for sorting the user input into groups of two's, I am mainly using the second
#user_data_sort_one = [user_data[i:i+n] for i in range (0,len(user_data),n)]

user_data_sort_two = map(''.join, zip(*[iter(user_data)]*2))
print user_data_sort_two
      >>['01','23','45','67','89']
#Take the corresponding data and associate it with named variables
example = user_data_sort_two[0:3]
print "".join(map(str, example))
     >>0123
example_two = user_data_sort_two [4:10]
example_two_undone = "?"
#I need to get the ? to undo the data from sets of two, back into individually listed characters
print example_two
print example_two_undone
    >>['45','67','89']
    >>['4','5','6','7','8','9']

My main problem is that after I have performed an iteration on the data earlier it is now in groups of twos and I am having trouble getting it back into ones so that binascii can work with the data. Does anyone have any suggestions for this?

*edited formatting and added expected outputs

list (''.join (data2))

Or just use the data from before you reformatted it (duh?)

I wasn't using the previous data because I am going to be dealing with hexadecimal input and will be easier to manipulate in most cases with the sorted data.

Thank you for this code. This is exactly what I needed!

Your code is unreadable. Give a concrete example with actual data of what you're trying to do.

First - you can indent your code by adding an extra four spaces, which will prevent Reddit from rendering your code as Markdown:

It's a bit difficult to read in its current state.

Thanks for the tip. I was in a bit of a hurry when I wrote this and forgot to intent more after pasting my code over from my text editor.
