Practice Assignments

1. a) Print Mathematical tables from 3 to 20.
   3 * 1 = 3
   3 * 2 = 6
   
   3 * 10 = 30
   
   4 * 1 = 4
   4 * 2 = 8
   
   20 * 1 = 20
   20 * 2 = 40
   
   b) Take Input Parameters Start=3 and End=20 from User through Keyboard. Print the same Mathematical Tables. If user gives the two inputs as 4 and 25, then the tables should print from 4 to 25.
   
   c) Take Input Parameters from a file called in.txt having 5 and 30 in first and second line. Your program should read the first two lines of this file and print Mathematical Tables from 5 to 30.
   
   d) Take Input Parameters 6,12 from a file called in.txt written on the same line separated by a comma. The output should get written to a file called out.txt. To go to next line, f1.write("/n")
   
   e) Take Input Parameters 7 and 10 from console. Output to 4 different files 7.txt, 8.txt, 9.txt, 10.txt
   
   f) Take Input Parameters 8 and 9 from console. Output in a separate directory called TABLES and with 8_yyyymmdd_hhmmss.txt (eg 8_20210828_110503.txt). Import datetime as dt, today=dt.datetime.now()
