- List names of all customers who live in a given zip code Feature 18: List names of all customers living in a given zip code. Input: Create a procedure with Cust_name, Cust_Zip and a cursor to store the select statement output into the cursor. Output: Displays a list of all the customer names for a specific zip code with the cursor. Example of calling the feature: Exec customer_name_by_ZIP(‘Daisy Brown’, 64277); using an exception tooTranscribed Image Text A summer camp offers a morning session and an afternoon session. The list morningList contains the names of all children attending the morning session, and the list afternoonList contains the names of all children attending the afternoon session. Only children who attend both sessions eat lunch at the camp. The camp director wants to create lunchList, which will contain the names of children attending both sessions. The following code segment is intended to create lunchList, which is initially empty. It uses the procedure IsFound (list, name), which returns true if name is found in list and returns false otherwise. FOR EACH child IN morningList { <MISSING CODE> Which of the following could replace <MISSING CODE> so that the code segment works as intended? IF (IsFound (afternoonList, child)) { A APPEND (lunchList, child)4: In the Department of Mathematics and Computer Science (MACS), undergraduate course codes begin with either M (for Mathematics courses) or CS (for Computer Science courses). Thereafter, the code has four (4) digits. The first digit is the year of study, which is 1 to 6. The second digit is the credit hours, which is again 1 to 5. For Mathematics courses, the third and the fourth digits is just a running index to differentiate the course from the others. For Computer Science courses, the third digit is the area of specialisation, which is from 0 to 4. The fourth and the last digit is just a running index to differentiate the course from the others. a) Draw a finite state machine (FSM) accepting/generating course codes in MACS. b) As the result of a) above, write the corresponding C++ function int is_MACS_course(char * str) { I/ C++ code which will determine whether or not the given string, str, represents the correct code for MACS courses.

Function Specifications: It should take a pandas dataframe as input. It should return a new dataframe, grouped by day, with the number of tweets for that day. The index of the new dataframe should be named Date, and the column of the new dataframe should be 'Tweets', corresponding to the date and number of tweets, respectively. The date should be formated as yyyy-mm-dd, and should be a datetime object. Hint: look up pd.to_datetime to see how to do this.***required width for Celsius value is 35, width Fahrenheit value is 35, both should be right-aligned/justified # convert_revised_1.py # We will try to print a table without using "string formatting"def main():print("celsius", "fahrenheit") for celsius in range (-50, 200, 20):fahrenheit = 9/5 * celsius + 32print(celsius, fahrenheit) revise the TWO print statements, one is before the "for loop", for Table Header another one is within the "for loop".

- Using Pandas create a function that takes as input the data set (for example: sets) and returns the total number of rows in the data (as an integer)3. Create a sequence that generates integers starting with the value 5. Each value should bethree less than the previous value generated. The lowest possible value should be 0, andthe sequence shouldn’t be allowed to cycle. Name the sequence MY_FIRST_SEQ.get_column_choice(): this function will allow us to ask the players which pocket they want to grab stones from. Since we know which row they are grabbing from (since it is not allowed to grab stones from your opponent’s side), we only need to get the column they want. As previously stated, we are using letters to represent the columns to make it easier on the player. This function accepts the current player (should be a 0 or 1), the board, and a list of letters (the same as the list you passed to the print_game_board function) and it will return the index of the column being chosen. The function should ask the player to enter a column letter, then it should check that the conditions listed below hold. If they don’t meet these conditions, it should ask again until it gets a valid letter, otherwise it should return the corresponding column index for that letter. Letter entered must be on the game board. It can be lower case or upper case. (Hint: this doesn’t need to be hard coded,…
