How do you overwrite in Excel?

I'm new to programming.

I'm trying to create a simple game of cards. I've created a function with the code below. So far, when you win or lose, I get one error message ("Unbalanced calls to begin/end appearance.") If you get 7 or more in the text box below is it okay? It doesn't work yet. Thanks
Private Sub ComboBox1SelectedIndexChanged(). Dim strPlayer1 As String. Dim strPlayer2 As String. Dim strWinner As String. Dim numAs As Integer. 'numAs = ActiveSheet.Cells(1, 2).Value 'Number of people
numAs = 2. strPlayer1 = "". strPlayer2 = "". strWinner = "0". If strComboBox1.Value = strComboBox2.Value Then
numAs = 3. strPlayer1 = "Player 1". strPlayer2 = "Player 2". strWinner = "Player 1". Else. numAs = 1. strWinner = "Player 2". End If. Worksheets("Sheet 1").Cells(1, 3).Value = strPlayer1 & numAs
Worksheets("Sheet 1").Cells(1, 4).Value = strPlayer2 & numAs
Worksheets("Sheet 1").Cells(1, 5).Value = strWinner & numAs

How do I change data in Excel using Python?

I'm trying to use the Python module for Excel to update a cell in Excel (Excel 2010). I have successfully been able to update the cell using the following: import xlwt. Book = xlwt.Workbook() book.addsheet('Test') testcell = book.getsheetbyname('Test').cell(2, 2)
Testcell.value = "This is a test" book.save("test.xls")

However, the problem that I am having is that the cell doesn't change until I exit the program. For example, if I open test.xls and run the program again, the cell remains unchanged. How do I change a cell in Excel using Python?

How to overwrite a cell in Excel using Python?

I have a huge sheet (more than 5GB) with different information. What I am trying to do is to write text message to a cell A1. Here's the code:
Import xlwt, win32com.client excel = xlwt.Workbook('sample.xls')
Sheet = excel.addsheet('sample.xls', numrows=0)
For in range(5): sheet.write(0, 'Hello, world!') # I'm only writing data and not formulas excel.save('sample.xls')
This code is fine, but every time I do it, I want to append Hello, world! to the end of cell A1 every time I run my code. So what I was thinking is to loop the cell A1, but every time it loops once it should write Hello, world!, not twice Hello, world! because that makes it looks strange.

Any suggestion on how to do it? Note: I'm using win32com.client.

If you want it to be formatted as a row with columns in the first column then use xlwt's WriteRow(). For example: excel = xlwt.Workbook() sheet = excel.addsheet('Sample') for in range(5): sheet.write(0, 'Hello, world!') # Write all cells without format for c in range(1,3): sheet.write(1, 2, ' # Save the workbook as an XLSX Excel file. Excel.save("test.xlsx")
Which will result in this when openend in LibreOffice / Microsoft Office Excel 2013: Which looks as desired. In XLSX file the first column is a title bar so this kind of structure needs to be kept and the data on each row needs to be separate.
