python AttributeError: 'NoneType' object has no attribute 'replace' in list

#@ Row 1, Column 4: Invalid character value for cast specification @#

BCC,01,12697,2013-12- 12,1.0,2014004,CR,ACCOUN TS PAYABLE,-86.23000,,2200-000-000,, ,,,,True,,0,False,,,False,,,,,,0.00000,0.00000

I am trying to remove the tab in the date value and elsewhere in each row of data. 

columndata = [str(items.replace('\t', '')) for items in list(row)]

However, this command returns the following error:

  File "apdetfac.py", line 60, in <listcomp>
  columndata = [str(items.replace('\t', '')) for items in list(row)]
  AttributeError: 'NoneType' object has no attribute 'replace'

I tried converting items to str as follows str(items) in list(row) but that generated another error. What to do?

Its difficult to tell what data you have, but this gives the right sort of answer:

row_str = 'BCC,01,12697,2013-12-\t12,1.0,2014004,CR,ACCOUN\tTS PAYABLE,-86.23000,,2200-000-000,, ,,,,True,,0,False,,,False,,,,,,0.00000,0.00000'
# note the '\t' in date and ACCOUNTS

row = row_str.split(',')

columndata = [str(items.replace('\t', '')) for items in row]

print(columndata)

Output:

['BCC', '01', '12697', '2013-12-12', '1.0', '2014004', 'CR', 'ACCOUNTS PAYABLE', '-86.23000', '', '2200-000-000', '', ' ', '', '', '', 'True', '', '0', 'False', '', '', 'False', '', '', '', '', '', '0.00000', '0.00000']

Of course this list can be joined back into a string:

new_row = ','.join(columndata)
print(new_row)

Output:

BCC,01,12697,2013-12-12,1.0,2014004,CR,ACCOUNTS PAYABLE,-86.23000,,2200-000-000,, ,,,,True,,0,False,,,False,,,,,,0.00000,0.00000

data = "'BCC,01,12697,2013-12-\t12,1.0,2014004,CR,ACCOUN\tTS PAYABLE,-86.23000,,2200-000-000,, ,,,,True,,0,False,,,False,,,,,,0.00000,0.00000'"

print(','.join(map(lambda x: x.replace('\t',''), data.split(','))))
>>>'BCC,01,12697,2013-12-12,1.0,2014004,CR,ACCOUNTS PAYABLE,-86.23000,,2200-000-000,, ,,,,True,,0,False,,,False,,,,,,0.00000,0.00000'
