It does.
Here is a short example of how to set the numeric formatting
of cells. There are more example in the xlwt documentation at
https://github.com/python-excel/xlwt/tree/master/xlwt/examples
--------
#!/usr/bin/env python2
import xlwt
def main():
w = xlwt.Workbook()
ws = w.add_sheet('Sheet1')
style_money = xlwt.XFStyle()
style_money.num_format_str = '[$$-409]#,##0.00;[RED]-[$$-409]#,##0.00'
for row in range(6):
ws.write(row, 1, 'Test')
ws.write(row, 2, 3.123456 - row)
ws.write(row, 3, 3.123456 - row, style_money)
w.save('test.xls')
if __name__ == '__main__': main()
