Practice in interactive mode

• Run Idle on your machine
  

  python3

• Practice with logical operators
  

  >>> 4 < 8 and 8 < 80
  >>> 4 > 8 or 8 < 80
  >>> not True
  >>> not False

• Write an if statement that checks the range of a variable
  

  >>> age = 25
  >>> if 16 <= age <= 65:
  ...    print("Your age is in the right range")
  ... else:
  ...    print("Your age is in the wrong range")
  ...

• Write some boolean expressions
  

  >>> 16 <= age  and  age <= 65
  >>> 16 <= age <= 65

• Set some boolean variables
  

  >>> minor = age < 10
  >>> minor
  >>> senior = age > 65
  >>> senior

• You should see
  

  4 < 8 and 8 < 80: True
  4 > 8 or 8 < 80: True
  not True: False
  not False: True
  
  num_1 < num_2 and num_3 <= num_4: True
  num_1 < num_2 or num_3 > num_4: True
  num_2 == num_2 and num_3 != num_3: False
  num_2 == num_2 or num_3 != num_3: True
