I have already existing excel file and at the beginning in my code i import data from first sheet.

Now i cant write points from two variables `(xw, yw)` into new sheet in excel to two colmuns (A1-A[Q] and B1-B[Q]).

`xw` and `yw` are arrays consisting of float numbers (example: 1.223, 2.434 etc.).

```py
Q = len(xw)
wb.create_sheet('Points')
sheet2 = wb.get_sheet_by_name('Points')
for q in range(1,Q):
    sheet2["A[q]"]=xw[q]
    sheet2["B[q]"]=yw[q]
wb.save('PARAMS.xlsx') 

```

**EDIT:**

I want to fill third column with zeros (C1-CQ). My code is below, but its start from C2, not C1. I did `sheet2[f"C{1}"]=0` but it looks bad. What is the solution?

```py
Q = len(xw)
zw= np.zeros(Q)
sheet2 = wb.create_sheet('Points')
sheet2[f"A{1}"]=0
sheet2[f"B{1}"]=T_r
sheet2[f"C{1}"]=0
for i, row in enumerate(sheet2.iter_rows(min_row=2, max_col=3, max_row=Q+1)):
    row[0].value = xw[i]
    row[1].value = yw[i]
    row[2].value = zw[i]
wb.save('PARAMS.xlsx')

```
