Create a program (Lab9_Act1_Write.py) that will read in data from the keyboard and store it in a file. Your program should prompt the user for the name of the file to use and then request values be entered until the user is done. This data should be written to two files: a text file, user_file_name.txt and a comma separated value file, user_file_name.csv. To help you with decision making, we suggest that you ask the user to input data representing students’...
