4.4/5 for Loops

• idea of repeating same code over again: iteration
• The for statement allows is to write programs that implement iteration

for name in ["Joe", "Amy", "Brad", "Angelina", "Zuki", "Thandi", "Paris"]:
    print("Hi", name, "Please come to my party on Saturday!")
        #prints a separate statement with each name in list

• name in this for statement is called the loop variable
• Line 2 is the loop body. The loop body is always indented. The indentation determines exactly what statements are “in the loop”. The loop body is performed one time for each name in the list.

Flow of execution of the for Loop

• control flow, or the flow of execution
  • interpreter always keeps track of which statement is about to be executed
• Control flow until now has been strictly top to bottom, one statement at a time: sequential
