My Excel workbook contains VBA subs and macros similar to those below; they sit in Module1.

How to call them using Python win32com module?

Public Sub setA1(ByVal s As String)
    ThisWorkbook.ActiveSheet.Range("A1").Value = s

Public Function getA1() As String
    getA1 = ThisWorkbook.ActiveSheet.Range("A1").Value
End Function

Many thanks in advance!

xl.Workbooks.Open(Filename="c:\\temp\\book1.xls",ReadOnly=1)
xl.Application.Run("setA1", '4')
res = xl.Application.Run("getA1")
