#  2006-05-23  File created.
#  2022-12-16  Converted to Python 3.

#  This is the main program of an example program in which
#  the given numbers are sorted.

#  The program files SortMain.py, InputOutput.py, and Sort.py
#  correspond to single program files (e.g. Sort.java) written
#  with other programming languages.

#  This program shows how Python functions defined in other
#  .py files can be used. In Python terminology another .py
#  file is another Python module. Modules must be imported
#  with import statements before the functions defined inside
#  the modules can be used.

#  When this program is executed, files InputOutput.py and Sort.py
#  must be in the same folder (directory) where this file is located.

import InputOutput
import Sort
 
list_of_numbers  =  []

print( "\n This program sorts the numbers that you enter"  \
      "\n from the keyboard. The program stops asking for new"  \
      "\n numbers when you enter a letter. \n" )

number_of_numbers_read  =  InputOutput.ask_numbers_to_list( list_of_numbers )

Sort.sort_to_ascending_order( list_of_numbers,
                              number_of_numbers_read )

InputOutput.print_list_of_numbers( list_of_numbers,
                                   number_of_numbers_read )


#  Note that there is the standard sort() method that can sort a
#  Python list. The list used in this program could be sorted
#  with the statement
#      list_of_numbers.sort() # sort to ascending order
#  This statement would sort the entire list, whereas
#  Sort.sort_to_ascending_order() can be used to sort a part of
#  a list.
