(b) Implement a function in Python to create a dictionary: {'a': 10, 'b': 20, 'c': 30, 'd': 40} and display each key-value pairs of it. Implement a function dict_check_add(dictionary, key, value) in Python to check whether a key of the given key-value pair already exists in the dictionary. If it is not, add the key-value pair to the dictionary.

Define a Python function which creates a dictionary where the keys are between the letters “a” and “h”, inclusive, and the values are square of keys’ ordinal value (Hint: check an ASCII table). The function should return the dictionary back to the caller. • Using the returned dictionary from your function, print the entire dictionary.• Using the returned dictionary from your function, print only the values of the dictionary.• Using the returned dictionary from your function, print only the keys of the dictionary.
1. Write a function invert_dict to reverse a dictionary, for example: >>> eng2sp = {'one': 'uno', 'two': 'dos', 'three': 'tres'} >>> sp2eng = invert_dict(eng2sp) >>> sp2eng {'uno':'one', 'dos':'two', 'tres':'three'} 2. Write a function print_dict to print all the key-values in a dictionary, for example: >>> d2 {'a': 'one', 'b': 'two', 'c': 'Three'} >>> print_dict(d2) a:one b:two c:Three
1. Write a Python function called add_daily_temp that is given a (possiblyempty) dictionary meant to hold the average daily temperature for each day ofthe week, a temperature value, and the day of the week for the recordedtemperature. The function should then add the temperature to the dictionaryonly if it does not already contain a temperature for that day. The functionshould return the resulting dictionary, whether it is updated or not.
Use Python for this question: Write a function piggyBank that accepts a sequence of "coins" and returns counts of the coins and the total value of the bank. the coins will be given by a list of single characters, each one of 'Q','D','N',P' , representing quarter, dime, nickel, penny the function returns a tuple with two items: a dictionary with counts of each denomination. They should always be listed in the order 'Q','D','N',P' the total value in whole cents of the amount in the bank Output for this question is in the attached picture
Consider the following python code: def carDict(data): d = dict() for c in data: if c not in d: d[c] = 1 else: d[c] += 1 return dcars = ['bmw', 'ford', 'toyota', 'ford', 'ford', 'bmw']tracker = carDict(cars) 1) How would you iteratively print out all the key value pairs in the dictionary tracker, using a loop?
How to write a function in python 3 that takes two dictionaries b1 and b2 and returns a new dictionary b3 which is the combination of b1 and b2 such that the function adds values for common keys. Input: b1 = {'a':1,'b':10,'c':3} b2 = {'a':2,'b':11,'d':4} Output: b3 = {'a':3,'b':21,'c':3,'d':4}
