map dictionaryWrite a Python program to map two lists into a dictionary.Sample Test CasesTest Case 1:Expected Output:Enter·the·number·of·elements:·2Enter·key:·1Enter·value:·20Enter·key:·2Enter·value:·30The·dictionary·mapping·is:{'1':·'20',·'2':·'30'}Test Case 2:Expected Output:Enter·the·number·of·elements:·1Enter·key:·1Enter·value:·abcThe·dictionary·mapping·is:{'1':·'abc'}
Solution
Sure, here is a Python program that maps two lists into a dictionary:
# Initialize an empty dictionary
dict1 = {}
# Get the number of elements from the user
n = int(input("Enter the number of elements: "))
# Loop for the given number of elements
for i in range(n):
# Get the key from the user
key = input("Enter key: ")
# Get the value from the user
value = input("Enter value: ")
# Add the key-value pair to the dictionary
dict1[key] = value
# Print the dictionary
print("The dictionary mapping is:", dict1)
You can run this program and enter the keys and values when prompted. The program will create a dictionary using these keys and values.

In a program, a dictionary contains lists of students and their courses. The teacher is interested to have a dictionary that has the courses as key and the students enrolled in each course as values. Each key has three different values. To address this requirement, write a function to invert the dictionary and implement a solution that satisfies the teacher’s need. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary. Also provide a technical explanation for the code and its output in minimum 200 words. Sample input: { 'Stud1: ['CS1101', 'CS2402', 'CS2001'], 'Stud2: ['CS2402’,’CS2001’,’CS1102’] } Inverted Output: { ‘CS1101’: [‘Stud1’], ‘CS2402’:['Stud1’,’Stud2’], ‘CS2001’: ['Stud1’,’Stud2’] ‘CS 1102’[‘Stud2’] } Programming Instructions: Print the original dictionary as well as the inverted dictionary. Include your the Python program and the output in your submission. The code and its output must be explained technically. The explanation can be provided before or after the code, or in the form of comments within the code.
