The one-liner way:<\/p>\n

import datetime\n\nunit[\"data\"] = [[item.strftime(\"%Y-%m-%d %H:%m:%S\") if isinstance(item, datetime.datetime) else item for item in row] for row in unit[\"data\"]]\n<\/code><\/pre>\n
As far as I’m concerned I’d wrap this in a couple utility functions though:<\/p>\n
import datetime\n\ndef format_item(item):\n    if isinstance(item, datetime.datetime):\n        return item.strftime(\"%Y-%m-%d %H:%m:%S\")\n    return item\n\ndef format_row(row):\n    return [format_item(item) for item in row]\n\nunit[\"data\"] = [format_row(row) for row in unit[\"data\"]]\n<\/code><\/pre>\n
As a side note: <\/p>\n
1\/ in your code you’re using a mix of indexed access (unit['data'][idx][0:5]<\/code> and direct item access (dd[9]<\/code>) when you could just use  dd<\/code> all over, ie <\/p>\n
dd[0:5] + (datetime.datetime.strftime(dd[9], \"%Y-%m-%d %H:%m:%S\"),) + dd[6:]<\/code> <\/p>\n
2\/ even if you needed indexes too, you don’t have to manually maintains the current iteration index (idx<\/code> in your code), you can just use for index, item in enumerate(sequence):<\/code><\/p>\n
3\/ finally, strftime()<\/code> is  a method of datetime.datetime<\/code>, so you can just call it directly on your  datetime.datetime<\/code> instance, ie: dd[9].strftime(\"%Y-%m-%d %H:%m:%S\")<\/code><\/p>\n<\/p><\/div>\n
