using python write the code.., for each pic..
Accessing a Dictionary Dictionaries are iterable objects that store associations between 'keys' and values Here is a dictionary that accociates weekday names with a 'day number. f'Sunday':0, 'Monday' :1, 'Tuesday' :2, 'Wednesday':3, Thursday':4, 'Friday' :5, 'Saturday' :6) Values can be retrieved from dictionaries using square brackets, in the same way that elements of a string or a list can be selected. The difference here is that the key goes within the square brackets. Write a function get value(dictionary, key) which returns the value for the given key in the given dictionaryExplanation / Answer
def get_value(dictionary, key):
try:
return dictionary[key]
except:
return -1
def get_value(dictionary, key):
if dictionary.get(key) != None:
return dictionary.get(key)
else:
return -1;
def big_keys(dictionary, val):
list = []
for k in dictionary:
if dictionary[k] > val:
list.append(k)
return list
def add_to_dict(d, key_value_pairs):
list = []
for i in key_value_pairs:
key = key_value_pairs[i][0]
val = key_value_pairs[i][1]
if get_value(d,key) != -1:
if get_value(d,key) != val:
list.append(key_value_pairs[i])
d[key] = val
return list
