???????? 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. No need to follow the pattern below)…
3) in python Copy the Plain Text UTF-8 version of Bram Sroker’s Dracula from the site:http://www.gutenberg.org/ebooks/345 into a text document called ‘dracula.txt’. Write pythoncode that reads the text document and counts the unique words and stores the words and countsinto a dictionary. Write the words and counts into a text file called ‘dracula words.txt’ by usingthe Python file handle method seen in class. Generate a list called ‘sorted counts’ that containsthe value and key pairs as tuples that are sorted in descending order based on the frequencies ofthe words. For example, it should be in the form:[(7423, ‘the’),(5640, ‘and’),(4499, ‘I’),(4462, ‘to’),(3673, ‘of’),(2891, ‘a’),(2384, ‘in’),(ect.) Here, the word ‘the’ occurs the most frequently. Output the top 10 most frequently occurringwords. How often does the word ‘Dracula’ come up in the entire Novel?Hint: use list comprehension. For the dictionary ‘counts’ the command ‘counts.items()’ returns anobject of type dict items that…
Using Python, write a program which opens a text file and loads the data into a dictionary where the key is the line # from the file and the value is the line of text from the file. For instance, if the file looks like: Hello,Welcome to Introduction to Big Data It is good to meet everyone.Hope you enjoy the class. The dictionary should look like: KEY VALUE 1 Hello, 2 Welcome to Introduction to Big Data 3 It is good to meet everyone. 4 Hope you enjoy the class. Then change it to a list and reverse the order of the lines of text and save it back to a new text file.
### Task 11 (8 points) Write a Python program that takes a String as an input andcounts the frequency of each character using a dictionary. For solvingthis problem, you may use each character as a key and its frequency asvalues. \[You are not allowed to use the count() function\] **Hint:** 1. You can create a new dictionary to store the frequencies. 2. Ignore case for simplicity (i.e. consider P and p to be the same).3. keys need to be lower case 4. Do not count space. Remove space before counting. =================================================================== **Sample Input:** "Python programming is fun" **Sample Output:** {'p': 2, 'y': 1, 't': 1, 'h': 1, 'o': 2, 'n': 3, 'r': 2, 'g': 2, 'a': 1,'m': 2, 'i': 2, 's': 1, 'f': 1, 'u': 1} =========================== here is my code but I don't know what is wrong def task11(in_str): # YOUR CODE HERE test_str = in_str.lower() dict_out = {} for i in test_str: if i in dict_out: dict_out[i] += 1 else:…
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
2- Consider the following Python dictionary: {'Wednesday': 'Wednesday', 'Thursday': 'chilly'} Using the in keyword, would 'Wednesday' be considered a member of this dictionary? Ensure that you select the answer which also includes a correct explanation. a. No, because it is not a value in the dictionary. b. Yes, because it is a value in the dictionary. c. No, because it is not a key in the dictionary. d. No, because it is not both a key and a value in the dictionary (not just one or the other). e. Yes, because it is a key in the dictionary. f. Yes, because it is both a key and a value in the dictionary (not just one or the other).

Regarding a dictionary, which of the following is not true? This is for python. A dictionary can contain another dictionary. A dictionary contains key-value pairs, typically separated by a colon. A dictionary can be modified. The contents of a dictionary can be accessed by using either its keys or by using indexing.

Write a program to create a dictionary class using BST that allows to insert, delete, display in-order and search records. Each record represents a book and should contain, book title, author name, number of copies, publication year. Insert the record using book title as key. Note: To get full marks, add data validations and constructors wherever applicable. WRITTEN IN C++
(PYTHON) a) 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. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases) 12
