Look out my window — And see random acts of grace — By everyone

Lest we go forward — Without knowing about lists — We would be wanting

---

Look both ways

• Back or ahead

Agenda

A random example

Example to motivate looping

• Program again_and_again.py

• Prints out the characters of a user-supplied string, character by character

• Program thats_amore.py

• Prints out a user-supplied string list of words, one by one

• Program ready_or_not.py

• Prints out the integers 0 to n-1 for user-supplied n; afterwards, prints out the phrase 'Ready or not here I come!'

---

Examples to introduce list capabilities

• Program thats_so_numbing.py

• Introduces list manipulation.
