# NoVowels.py  reads a line of text and extracts all the vowels from it.
# Input:  a single line of lower-case words, separated by spaces
#       (no punctuation is used)
# Output:  the line of text without the vowels, and
#        spaces are preserved in both output lines
# Example: for the input text,    this is a line of text
#        the output is:  ths s  ln f txt

# IMPORTANT: in English,  a, e, i, o, u  are always vowels.
#   y  is sometimes a vowel and sometimes not, 
#   but we will pretend that it is always a consonant.

# assert: all of  text[0]..upto..text[len-1] were examined, hence
