Create a JSON file named invoice.json and write into it the following dictionary: invoice_dict = {* invoice": [{'part_num': 500, 'part_descr': 'hammer', quantity": 10)}. {{part_num": 600, part_descr": "screwdriver', "quantity": 5)}]} Then, read the file with catching exception like FileNotFoundError in a try suite. Display its pretty-printed JSON (p.330).

???????? 1:You are given a list of courses that are currently available in BRACU that looks like the following: courses = ['CSE110','CSE111','MAT620','CSE520','EEE361','CSE650','MAT510']. All courses till 400 level (499) are for the undergraduate students whereas any courses above 500 are for the graduate or masters students. Write a python program that creates a dictionary from the above list where the keys will be each department name (CSE,EEE,MAT for the above example) and their values will be a dictionary of two keys -Undergraduate Courses and Graduate Courses. Each key will have courses that fall in Undergraduate and Graduate level respectively. Sample Input - No need to take input ['CSE110','CSE111','MAT620','CSE520','EEE361','CSE650','MAT510'] Sample Output: (You just have to print the resultant dictionary.

Answer the given question with a proper explanation and step-by-step solution. For this question use the file data1.csv The file contains information on various customers. Each customer has a unique customer id. The data also has information on age income and Gender of the customers. Space can be used as a delimiter for this file. Find the following: A) The total number of the rows in the file. B) The number of unique customer ids in the datafile. For this question create a set object which will only allow you to add unique customer ids. C) The program asks user to provide an id and prints information about that customer. Make sure to take care for the errors due to invalid id (i.e., id does not present in data). Print “id not found” when id is not found. Save the file as Solution1.java. You can use either File Reader or Scanner classes to read the data in the csv file. Your program should print the following after filling the blanks with the appropriate values Outcome: The total…
get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary.
Complete the below function that takes a file name and a list as arguments andreads the text within the corresponding file, then creates a dictionary whosekeys are the characters of the provided list, and the values are the counts ofthese characters within the text. If a character in the list is not included in the text, "0" should be written in the dictionary as the value of this character. The function returns the created dictionary as a result. If the file does not exist, then the function returns an empty dictionary. Here is an example case, assuming a file named "sample.txt" exists with the following content: ----- sample.txt -----This is an example sentence.This is yet another sentence.------------------------- >>> text2dict("sample.txt", ['a', 'b', 'c', 't']){'a':3, 'b':0, 'c':2, 't':4} """ def text2dict(filename, characters):return # Remove this line to answer this question

Please help me with the assignment below The assignment: Make a telephone lookup program. Read a data set of 1,000 names and telephone numbers from a file that contains the numbers in random order. Handle lookups by name and also reverse lookups by phone number. Use a binary search for both lookups. This assignment needs a resource class and a driver class. The resource class and the driver class will be in two separate files. The driver class needs to have only 5 or 7 lines of code. The code needs to be written in Java. Please help me with exactly what I asked for help.
