Dictionaries 👷🏼‍♂️👷🏼‍♀️

Matched key:value pairs

my_dict = { 'colour':'blue', 'points':20, 'super_factor':3 }

action	code
access a value	my_dict['colour']
adding items	my_dict['new_item'] = 'brand new thing'
modifying items	my_dict['colour'] = 'green'
removing items	del my_dict['points']

method	action
dict.keys()	lists all the keys in the dict
dict.values()	lists all the values in the dict
dict.items()	lists all the items in the dict
dict[key]	returns the value associated with that key, throws an error if key doesn't exist
dict.remove[key]	removes the k:v pair (also del dict[key] does the same thing)
dict[key] = value	adds the k:v pair or updates the k:v pair if it already exists in the dict

Zipping

keys = ['a', 'b', 'c']
vals = [1, 2, 3]
mydict = dict(zip(keys,vals))

mydict now equals -> {'a':1, 'b':2, 'c':3}
