Python Openpyxl将日期写为Excel作为短日期

Question

I am trying to write dates to an excel file using Openpyxl. I am using the following lines to write the date.

dttm = datetime.datetime.strptime(ls25Dict[cell.value][2], "%m/%d/%Y" )   
ws1['B'+ str(cell.row)].value = dttm

This writes the date to excel but in the wrong format. This is the output:

2018-01-09 0:00:00

I am trying to get it to be 1/9/2018. Basically change the format to Short Date in excel.

Anyone know how to change it before the date is written to excel?

Answer 1

In Excel you always have to provide your own format for dates and times, because these are stored as serials. openpyxl defaults to ISO formats for minimal ambiguity.
