While True: 
        my_now = datetime.datetime.now().strftime("%d.%b %Y %H:%M:%S") 
        myfile =  open("my_file.txt", "a")         
        myfile.write("Added at {my_now}")

Use the append mode ('a') to open the file. Compose cursor focuses to the furthest limit of document. Make use of the write() function to append "n" at the end of the file. Utilize the write() function to add the specified line to the file.
