Post #1: Briefly respond to the questions below by Tuesday.Post a new metsage in narrative form (i.e. no bullet points) that addresses the following questions:• In your own words, explain the concept of variable scope. Include one or more code fragments that you write for this discussion post to help illustrate your case. Clearly markas appropriate any code fragments as either "script" code or "function" code, and use comments in your code to note the locality of each variable at least the first time thevariable appears in the script or function. If a variable is lọcal in scope, be sure to notate what the variable is local to (i.e. the script, a particular function, etc.). Your code forthis discussion post should include at least two different local variables, and at least one global variable.Compare and contrast separate function files with anonymous functions. In your opinion, when may it be best to use one over the other? Can you use them interchangeablyin all circumstances?

Try to create a dictionary that has a listing of people and includes one interesting fact about each of them. Display each person and their interesting fact on the screen. From there, alter a fact about one of the people on the list. Also, add an extra person and corresponding fact to the list. Display the newly created list of people and facts. Try running the program multiple times and take note of whether the order changes.

Create a data type that allows you to insert, remove the maximum, and delete the minimum (all in logarithmic time), as well as locate the maximum and find the minimum (both in constant time). Use two piles as a hint.
Write three static comparators for the any Point2D data type , one that compares points by their x coordinate, one that compares them by their y coordinate, and one that compares them by their distance from the origin. Write two non-static comparators for the Point2D data type, one that compares them by their distance to a specified point and one that compares them by their polar angle with respect to a specified point.

1. Create a UML using the UML Template attached. 2. In this lab, you will be creating a roulette wheel. The pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Create a class named RoulettePocket. The class's constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket's color, as a string. Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user…

Split blood pressure into systolic and diastolic blood pressure with integer as data type readings and remove the original column. Examine the data and look for predictor columns that are indicator variables, 0 or 1. Convert the data type to Boolean. Using code prepare lists of predictor column names for each data type. Make sure all the predictor columns are included in one and only one list. Print the length of the list of each data type and the sum of the lengths and verify that all predictor variables are accounted for in the lists. Use f-string to align the numbers properly.
please include a picture of the program and the output too and thank you!!!

First class was posted in this question, third class will be posted in a different question, please refer to it, thank you: https://www.bartleby.com/questions-and-answers/computer-science-question/34b2a175-1365-4989-a811-33c7e8b66a7b Do not change the function names or given starter code in the script. Each class has different requirements, read them carefully. Do not use the exec or eval functions, nor are you allowed to use regular expressions (re module). All methods that output a string must return the string, not print it. If you are unable to complete a method, use the pass statement to avoid syntax errors. Section 2: The Calculator class Implement a class that calculates mathematic expressions. The input passed to this Calculator is in infix notation, which gets converted to postfix internally, then the postfix expression is evaluated (we evaluate in postfix instead of infix because of how much simpler it is). More details about infix to postfix conversion can be found…
