i want to pick the last 20
items of a list copy them a new spreadsheet, and once copied i want to delete
them from the first spreadsheet.
i have the first part going (copy the last 20) but im not sure how to delete
that cell so it doesnt appear as none
after i save it.
filtered = [-20:] how do i delete those 20 cells from the spreadsheet?
def cell_values(somesheet):
# extract the last 20 items from the worksheet
filtered = [x for x in somesheet.rows if x is not None]
last20 = filtered[-20:]
extracted_values = []
for row in last20:
for cell in row:
# print cell.value
extracted_values.append(cell.value)
the problem is that filtered = [x for x in sheet.rows if x is not None]
is not working and actually appending None
items to the filtered
list
how can i make sure that its only picking the last 20 items that are not none
? as well as delete them once i have picked them from the list
[x for x in somesheet.rows if x is not None]
will return a list of rows because ws.rows
returns a list of rows.
There is currently no way to remove cells from a worksheet. The best thing is to set their values to None. Unless they have special formatting they will be removed from the worksheet when the file is saved. Calling ws.garbage_collect()
is deprecated because it makes no sense.
