如何在 python 上的 openpyxl 的帮助下在现有的 xlsx 文件上写入文本？

Question

Most of the tutorials are outdated and I am unsuccessful at writing on an xlsx file with the help of python.

Here is some code I used:

import openpyxl 
wb = openpyxl.load_workbook('C:/Users/user/Desktop/pytranslate.xlsx')
path = 'C:/Users/user/Desktop/pytranslate.xlsx'
ws = wb['Sheet1']
ws.cell(row = 1,column = 1,value = 'need for meas')
val1 = ws['A1'].value
print(val1)
wb.save(path)

The program ends with no error but I cannot see any output on the xlsx file.

I used this code to test. I created an empty excel document first. It updated correctly.

import openpyxl 
path = 'pytranslate.xlsx'
wb = openpyxl.load_workbook(path)
ws = wb['Sheet1']
ws.cell(row = 1,column = 1,value = 'need for meas')
val1 = ws['A1'].value
print(val1)
wb.save(path)

Output (excel)

If your document is not updating, confirm you have correct permissions to the file and folder.
