Column with spefic name in python

Dear all.

I wanna write simple code.

Where i wanna create excel file with specific column with names. like slno,dateand time, mode , etc. and i wanna write the data received from Serial monitor in indivual columns.

let me know the following
1) how to create excel file with column labeling
2)how to write into indivual column
3)how to give delay in the program.

Must you write directly to excel? An alternative: create a csv file you'd later load into excel.

You can delay using

import time
time.sleep(floating_point_seconds)

can you explain with simple code for writing into excel sheet with label specified

No. I recommend:

"com objects" were the method you needed. Maybe Microsoft uses something else now.
