Unit 3 Section 8

1) iteration: a repeating portion of an algorithm, repeats a specified number of times or until a given condition is met

2) Have an string with characters inside it, and iterate through the string to find different vowels and print the statement only using the vowels

text = "Hi my name is Amay"
for char in text:
   if char == "a" or char == "e" or char == "i" or char == "o" or char == "u" or char == "A":
      print(char)

i
a
e
i
A
a

Unit 3 Section 3.8.2

1) Iteration Statement - cause statements to be executed zero or more times, subject to some loop-termination criteria

for i in range(10, 0, -1):
   print(i)
