Loops

Use the for loop to iterate over a data structure.

colors = ["red", "blue", "green", "pink"]

for color in colors:
  # This will print the color name uppercased, e.g. 'RED'
  print(color.upper())

The while loop is used to do an action indefinitely.

color = None

# Ask about a color until "red" is provided
while color != "red":
  color = input("What's the right color? ")
