# get method is used to get a value that is inside a dict. This is quite useful because - # When we call a key in the dict that does not exist suppose 'age', if we say print age from this dict. # Then we know this dict does not have a age key, This throws an error. # If we are in a video game and we want something that does not exist like magic potions - The game crashes # This is avoided using get method instead of regular calling. This certainly returns a value None. # The program continues normally and we can also set a default value for the key we are calling! dictionary = { 'basket': [1,2,3], 'greet': "hello" } print(dictionary.get('age',55)) # 55 is the default value. # Another way of creating dict user = dict(name = 'naruto') print(user) # To check if the key:value pair is in the data structure print('age' in dictionary) print('basket' in dictionary) # To only look for keys. # .keys() method # To grab or look for only values. # .values() method # To look at everything in general # .items() method # If we clear the information in the first user - The copy is not going to change. user = dictionary.copy() print(user) # pop removes the actual value print(user.pop('greet')) print(user) # To randomly pop a key:value pair - 'popitem' print(dictionary.popitem()) print(dictionary) # Modern python does not removes it randomly as this function was updated in python 3.7 # To remove the last key:Value pair that was inserted into the dict. # To update a item or enter a new item we use the update method. print(dictionary.update({'age':55})) # we don't have a key called age. print(dictionary)
