#  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 TestSieveOut
#
#  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 
#  follow example GeneralTemplate.py by placing your main program in a 
#  function called main(), and call it from a conditional statement.
#
#       def main():
#          # your code for main program
#
#
#
#       # end main()
#
#       if __name__=='__main__'
#
#          main()
#
#       # end if 
#
#  The above test will work on any Linux or Mac computer, not just the Unix 
#  timeshare. If you want to do the same test on Windows PowerShell, use the
#  following form of the diff command.
#
#       python TestSieve.py > myOutput
#       diff (cat myOutput) (cat TestSieveOut)   
#  
#  Again, no output means the files myOutput and TestSieveOut are identical.
