How do I split a column of a csv file in excel using python 3.3?

P: 7
I have a column of some hundreds rows, obtained by a python program,each cell containing 4 unequal (in length) strings,like:
adfhyhh ihhgfdtykk red piuol
How can I split it with python in 4 colomns,with each cell containing one string?

Perhaps I don't understand your question. It is somewhat vague.
Expand|Select|Wrap|Line Numbers
  1. >>> cell = "adfhyhh ihhgfdtykk red piuol"
  2. >>> columns = cell.split()
  3. >>> columns
  4. ['adfhyhh', 'ihhgfdtykk', 'red', 'piuol']
  5. >>>

1 adfhyhh*ihhgfdtykk*red*piuol adfhyhh ihhgfdt red piuol
2 ehethe tthy tytuiuu aaaaaaa ehethe tthy tytu aaaaa

You can directly read the Excel workbook contents with xlrd, and the data is formatted so you can access the cell elements. What does your data look like after is is read by "a python program"?

I didn't say «read by a python program»,so I don't undrestand well your question.
If you meant how I created the cv file:with «f.write('file.csv','w')».
I expect a solution smth like «column.split».

"What does your data look like?" Since you don't understand me and I don't understand you, I'll take a guess.

  1. data = """3d3cd455 c6dd 4390 08712b657ec7

You can create 4 columns in each row by replacing the space character with a comma.
Expand|Select|Wrap|Line Numbers
  1. data = data.replace(" ", ",")
If you want to do it in a more complicated way:
Expand|Select|Wrap|Line Numbers
  1. "\n".join([",".join(item.split()) for item in data.split("\n")])
