#  TestSieve.py
#  Tests function makeSieve() in program Sieve.py
#
#  Place this program in the same directory as Sieve.py, and run it. The
#  expected output is contained in the file TestSieveOut. 
#
#  To test your program on the Unix timeshare, transfer the files Sieve.py, 
#  TestSieve.py and TestSieveOut to the timeshare and place them in the same
#  directory. Perform the following commands. 
#
#       python3 TestSieve.py > myOutput
#       diff myOutput TestSieveOutput
#
#  The second line should have no output. In other words, if diff gives any 
#  output at all, then the two files are not identical. This would indicate
#  either that your makeSieve() function is incorrect, or that you did not 
#  place your main program in a conditional of the form
#
#       if __name__=='__main__'
#
#          # your code for main program
#
#       # end if 
#
#  Note: The above test will likely work on any Linux or Mac computer, not
#  just the Unix timeshare. If you want to try diff on Windows PowerShell,
#  you will have to study the diff command in that environment.
