Answer 1

You have at least four problems, three of which are on the line ou_f.write([str(date,'UTF-8')]) .

• First, date is a list and you cannot convert a list to a string with str() .
• Second, you pass a list to ou_f.write() , but it requires a string.
• Third, you opened the CSV file in the binary mode.
• Fourth, you created a CSV writer but never used it. Using the CSV writer solves the first two problems:

-

with open('indata.csv', 'w') as CSVreport:
    wr = csv.writer(CSVreport)
    wr.writerow(date)

Answer 2

u mispelled utf on your write line

also check out the struct module for packing and unpacking binary data, which is what utf8 encoding does. you can check to see what you're actually passing to the write() function, also i think your script itself has to be utf8 encoded

'w' opens for ascii pack/unpack, 'wb' writes the data as you pass it. 'w' is pretty much a shortcut for python to do the packing internally for ascii. if you're writing utf-8 data you should research if 'w' can handle this correctly. and its questionable if you even need to use utf-8. ascii covers 256 characters which includes the american date/time notation. also, why not close the file?
