# Thrash Coding with Python for Advanced Python Programmers.
# These Python examples might be a bit tricky for beginners to fully
# understand. However, this is what Python is sometimes all about.
# These Python program examples below create fun auto typing
# text, using the 'len()' function within a while-loop to count the entire
# length of text, letter by letter, including empty spaces in between
# text words/sentences alike.
