     • int()
   • Float

       • 59.6

2. Iteration (Loops)

   • While loop
     • while CONDITION:
       • The condition is a statement that may be true or false
         • the code will keep repeating until the condition is false
           • If the condition is always true, the code outside of the loop will never run
             • name= "Bob" if name == "Bob" print("Hello")
               • "Hello" will only print once
     • While true
       • Using True ensures that the condition is always true
         • The indented command will run over and over forever
           • name= "Bob" while name == "Bob" print("Hello")
             • "Hello" will keep printing until the program is stopped
   • The process of repeating a section of code multiple times

3. Variables

   • A name you assign to a value
     • myName = "Bob"
       • A variable called myName is created
       • The value, "Bob" is assigned to the variable
   • myName = input()
     • the input() function means that the variable "myName" can be stored as anything
