openpyxl - can not iterate over excel rows

Question

I have a problem with iteration with openpyxl

wb = openpyxl.load_workbook(pfad,read_only=True)
sheet = wb.active
max_row = sheet.max_row    
for row in sheet["A1":"B4"]:
    print(row)
    for cell in row:
        print(cell.coordinate)

I should get the response of the coordinates from A1 to B4. But instead I got only A1 to B1:

(<ReadOnlyCell 'Tabelle1'.A1>, <ReadOnlyCell 'Tabelle1'.B1>)
A1
B1

If I used for row in sheet.iter_rows(min_row=1,max_row=4,min_col=1,max_col=2) : instead of for row in sheet["A1":"B4"] , I got the same result

That means, I can not iterate through the 2., 3. and 4. rows

I don´t know why it dosen´t work. Maybe I have ignored something? Thanks for any help!

======================== the problem is solved It is one part of a function and I inserted "return" the wrong way....

========================= in addition

the function looks like:

def excel_to_dict(pfad):
    wb = openpyxl.load_workbook(pfad,read_only=True)
    sheet = wb.active
    list1 = []
    max_row = sheet.max_row
    print(max_row)
    for row in sheet["A1":f"A{max_row}"]:
        print(row)
        for cell in row:
            print(cell.coordinate)
            c_value = cell.value
            print(c_value)
            list1.append(c_value)

        return list1

see...? wrong indentaion bevor return so only the first row was returned.... I have changed the indentaion so everything is ok...

You can just use sheet.rows to get all rows

>>> wb = openpyxl.load_workbook("excel.xlsx", read_only=True)
>>> sheet = wb.active
>>> rows = sheet.rows
>>> for row in rows:
...     print(row)
... 
(<ReadOnlyCell 'Sheet1'.A1>, <ReadOnlyCell 'Sheet1'.B1>)
(<ReadOnlyCell 'Sheet1'.A2>, <ReadOnlyCell 'Sheet1'.B2>)
(<ReadOnlyCell 'Sheet1'.A3>, <ReadOnlyCell 'Sheet1'.B3>)
(<ReadOnlyCell 'Sheet1'.A4>, <ReadOnlyCell 'Sheet1'.B4>)
