Setting Cell Formats with xlwt format strings

import time
import datetime
Time = datetime.datetime.now()
Currency = 234

#Format Date
style1 = xlwt.XFStyle()
style1.num_format_str = 'DD-MM-YY'

#Format Currency
style2 = xlwt.XFStyle()
style2.num_format_str = '$#,##0.00'

workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('Sheet1')

worksheet.write(0, 1, Time, style1)
worksheet.write(0, 2, Currency, style2)

I've found a list. I was just being stupid about looking for it.
The GitHub project has a list of number format strings here:
