Imagine a grocery store that has various items for sale. Each item is uniquely identified by a string name. However, due to some limitations in the store's inventory system, sometimes the same item gets entered more than once in the list of available items. Your task is to write a Python program that takes a list of item names and counts the unique items in it. Your program should then return a dictionary where the keys are the unique item names and the values are the counts of those items in the list. For example: If the input list is ["apple", "banana", "apple", "orange", "banana", "apple"], the output should be {'apple': 3, "banana": 2, 'orange": 1}. Requirements: Your program should be written in Python. You should not use any third-party libraries. Input: A list of n (1 <= n <= 10^5) string elements, where each string represents the name of an item in the grocery list. Output: A dictionary with keys as unique item names and values as their counts in the list.

Write a program that creates a dictionary containing the U.S. states as keys and their capitals as values. (Use the Internet to get a list of the states and their capitals.) The program should then randomly quiz the user by displaying the name of a state and asking the user to enter that state’s capital. The program should keep a count of the number of correct and incorrect responses.
In python: student_dict is a dictionary with students' name and pedometer reading pairs. A new student is read from input and added into student_dict. For each student in student_dict, output the student's name, followed by "'s pedometer reading: ", and the student's pedometer reading. Then, assign average_value with the average of all the pedometer readings in student_dict..
This is in Python Capital Quiz. This is a problem in which you use dictionaries. Write a program that creates a dictionary containing twenty (only twenty) States of the United States and their State Capitals. The States of the United States should be the keys. The program also should randomly quiz the user by displaying the name of a State and asking the user to enter that state's capital. The program should keep of a count of the number of correct responses. The program should ask the user how many times the user wants to play. If the user says 6, the quiz should run six times and the final output should say, you played this game six times and you got the answers correct four times (if the user got four answers correct).
Question-2: Write a Python program that takes a string as an input where multiple numbers are separated by hashes(#). Your first task is to create a list of numbers and print it. Your second task is to create a dictionary that will have the index of the list as key, and for the even indices, multiplication from start to that index as value, while for the odd indices, summation from start to that index as value. Finally, print the dictionary. . ================================================ Sample Input 1: 1#2#3#4 Sample Output 1: [1, 2, 3, 4] {0: 1, 1: 3, 2: 6, 3: 10} Explanation 1: key 0 → value 1 key 1 → value 1+2 = 3 key 2 → value 1x2x3 = 6 key 3 → value 1+2+3+4 = 10 ================================================ Sample Input 2: 5#6#7 Sample Output 2: [5, 6, 7] {0: 5, 1: 11, 2: 210} Explanation 2: key 0 → value 5 key 1 → value 5+6 = 11 key 2 → value 5x6x7 = 210.

USING PYTHON. Write a program that uses a dictionary to perform simple contact tracing . The key is the patient number and the values is a list of patient numbers who are close contacts of this patient. The program inputs the patient number and list of contacts for exactly 3 patients. Each patient has exactly 2 contacts. This data is then stored in a dictionary with the patient numbers as keys, and the list of contacts as values. The last input is the patient number to query, and the program prints the list of close contacts. It then also prints the list of close contacts of those in close contact to the patient queried. If there is no patient record for a contact, the program prints 'No Data'. See sample input and output
Write a Python program that will take a string of alphabets as the input from the user. Then, your program will then check the occurrences of uppercase and lowercase characters in the given string. Your task is to make a dictionary and print it, whose keys will be the lowercase of the unique characters that occur in the given string and the values will be a list containing the count of its lowercase frequency as first indexed value and uppercase frequency as second indexed value. For solving this problem you can consider the KEY to be NOT case-sensitive and the VALUE to be CASE-SENSITIVE.
