python - Changing date format of a dataframe /column

Question

for time in df[col]: datetime.datetime.fromtimestamp(int(time))

Why is not updating directly the dataframe df[col]? My aim is to update one column of a data frame with new date format.

Answer 1

I solved; I creat a list and update the related column of the dataframe with the list.

a_list=datetime.datetime.fromtimestamp(int(time)) df[col]=a_list
