Question

We picked the variable name user_dictionary because it will be a dictionary that is created by a user. Other names could be appropriate as well! Though it may seem unnecessary, we'll add a print statement to remind ourself that user_dictionary is empty. Next we'll build up the for loop! Save & Run Load History Show CodeLens 1 # initialize a dictionary 2 user_dictionary - {} 3 print("--- keys in user_dictionary: " + str(list(user_dictionary.keys()) + 5 # write a for loop that will iterate five times. I can use the range function for 6 for - in range(5): print("---------- LOOP HAS STARTED -- # in the for loop, I should ask for input from the user 8 # next, I should separate the words # finally, I should add the key value pair to the dictionary print("---------- LOOP HAS ENDED --

Hello there, following are the screenshots of code and its output.

According to the problem statement, code is implemented. To check wheather dictionary is empty or not, I created a seprate fuction. I also added the comments in code for better understanding   

н # initialize dictionary user_dictionary = {} print("--- ----------Keys in user dictionary" + str(list(user_dictionary.keys()) + " ь л о # function that will check whether dictionary is empty or not со def dictionary_empty(): print("The original dictionary : " + str(user_dictionary)) res = not bool(user_dictionary) print("Is dictionary empty ? : " + str(res)) # function called to check dictionary is empty or not dictionary_empty() # for Loop using range that will iterate for 5 times for _ in range(5): print("Loop has started") # inputs are accepted in pair of key and value. # split is a method used break the given string by the specified separator which is "blank space". X, y = input("Enter a two value: ").split() # dictionary_name. update(key:value}) method is used to add key value pair in dictionary user_dictionary.update({x: y}) print("Loop has ended") # print the contents of dictionary print(user_dictionary) 27

output: As input is not specified by you, i provided input in key:value pair like key1 value1, key2 value2 respectively. At the end of loop, all the contents of dictionary are shown.

- --Keys in user dictionary[]--- The original dictionary : {} Is dictionary empty ? : True Loop has started Enter a two value: key1 value1 Loop has ended Loop has started Enter a two value: key2 value2 Loop has ended Loop has started Enter a two value: key3 value3 Loop has ended Loop has started Enter a two value: key4 value4 Loop has ended Loop has started Enter a two value: key5 value5 Loop has ended {"keyl': 'valuel', 'key2': 'value2', 'key3': 'value3', 'key4': 'value', 'key5': 'value5'}
