==== Python Club Topics - Dictionaries ====

==== Dictionary ====
  - Often shortened to "dict"
  - Multiple values under 1 variable name
  - Used to store collections of data
  - Data stored in key & value pairs
  - Ordered ( starting in Python 3.7 )
  - Keys **CANNOT** be duplicated
  - Created using curley braces ( eg. { } )
  - key pairs **CAN** be changed

==== Dictionary Example ====
  - Create a dictionary<code python>
my_car = {
  "brand": "Ford",
  "model": "Focus",
  "year": 2010
}
print(my_car)
print("This brand ==> " + my_car["brand"])
</code>
  - Use the **len()** function<code python>
my_car = {
  "brand": "Ford",
  "model": "Focus",
  "year": 2010
}
print(len(my_car))
</code>
  - Change the value under a key<code python>
my_car = { 
  "brand": "Ford",
  "model": "Focus",
  "year": 2010
}
my_car['model'] = "Mustang"
print(my_car)
	</code>
