in openpyxl, how to set the font to 'centred'?

[Pedroski55]

I have the following code to set the font in my excel table using openpyxl:

ft1 = Font(name='Arial', size=20)

for sheet in targetFileSheetNames:
    targetFileActiveSheet = targetFile[sheet]
    maxRow = targetFileActiveSheet.max_row
    maxCol = targetFileActiveSheet.max_column
    for colNum in range(2, maxCol + 1, 1):
        for rowNum in range(1, maxRow + 1):
            targetFileActiveSheet.cell(row=rowNum, column=colNum).font = ft1

I would also like to have the text in the middle of the cell. I can't see how to set that.

Could someone please give me a tip? (I know that centre in American is 'center' !
