Logical Operators

Given what we know so far, we know the result of comparing two numbers or string lengths - it's either True or False. We know that Boolean values and Boolean expressions (code that needs to be evaluated to True or False) can use logical operations or/and/not. For other data types we can get Boolean expressions with comparative operators.

# All the following code evaluates to True
1 == 1                          # Equal to
'Chloe' == 'Chloe'              # Works for strings as well
2.001 != 2                      # Not equal to
'Chloe' != 'chloe'              # Case matters, these aren't equal strings
1 > 0                           # Greater than
3 < 5                           # Less than
15 >= 15                        # Greater than or equal to
# The above is equivalent to (15 > 15 or 15 == 15 )
amount_of_apples = 50
a <= 1400                       # Less than or equal to

Exercises

1. Work out whether the following would be True or False:

   1. 10 < 17 or (not False and 7 == 7.0)

   2. 'Justin' == "Justin" 3.

   3. not (10 == 1 or 1000 == 1000)

   4. "bunji" == "bunji" or "machel" == "soca king"

   5. energy_level = 3
      low_energy = energy_level < 5
      likes_coffee = True
      low_energy and likes_coffee
