Please read important information first. Description Your task is to write the code for calculating and printing the standard deviation for a sample of 4 numbers. The input numbers will be provided by the user, and there will always be 4 numbers. You must handle the input taking part, and DO NOT WRITE ANY PROMPTS for the user while taking the input. The sample standard deviation formula is provided in the image below. Assume that input numbers will always be real numbers. While printing DO NOT MODIFY THE FORMATTING OF THE OUTPUT, OR APPLY ANY PRECISION ALTERING OPERATIONS SUCH AS ROUNDING. E (ri-ravg)² i=1 n-1 Check the examples for further clarification. Keep in mind that we will be grading your code not just based on these examples, but other cases as well, so try to write code which can handle all possible cases. Important: If for some reason your solution is correct but does not receive a full grade due to precision, contact us and we will update your grade. Warning: You are not allowed to use imports. Examples: INPUT OUTPUT 0.0 -4 3.75 5 1 3.9915274853953675

Please read the question first and than only answer if you can. I will flag your answer if you will provide a wrong code.
Note:l need new answer, please Don't reply to me last answer Part (1): Write a Scilab code to calculate the surface area and volume for a cube, cuboid, cone, and cylinder. The user should specify the shape followed the required dimension (ex. For cube input base, for by cylinder input radius and height etc.......) Ask the user to enter the shape. • If the user entered any wrong shape other than mentioned above, display the message "Wrong Option" • Ask the user to enter the required dimensions. Ask the user to specify the required output (Surface area or volume). Display the specified output. Comment on cach line in your code.

Please do not give solution in image format thanku Acompany has hired you to develop an application to generate passwords for their employees’ accounts. The application prompts the user to provide one single line of text with an employee’s full name in the following format “forename surname” at a time. (Please note that you are not required to validate the input, we assume that the input is well-formed.) Next, the application uses the given full name to create the corresponding item. Note that the application should work irrespective of how the user provides the full name i.e. using upper-case letters, lower-case letters, or a combination of both upper-case and lower-case letters. You should use the full name as provided i.e. you should not modify the given full name to a different letter case.

LAB ASSIGNMENTS IMPORTANT: you should complete the PDP thinking process for each program. Turn in items: 1) fullname_regex.py - Ask the user to enter the source text to search, such as the name_source variable here: name_source = input('Enter full name in this format - first middle last'). Then, you can adapt the first two code lines from lesson slide 13, to search this new source. Edit the code to match the new situation and change the regex pattern to identify text that could be a full name. Hints: Initially write your regex pattern to check if the user enters three words separated by a space. Then, strive to make the regex adaptable if the person's full name has more than or less than 3 words. Then, think about allowing (not requiring) common characters like a period, hyphen or '. Slides 11-13 should be helpful. 08 For printing, end with a conditional block that provides an appropriate message if there is a match or not.

Assignment details: Replace all the 0 (Zero) digits in your ID by 4. Example: If your ID is 38104680, it becomes 38144684 Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table; Letter Replace by Digit Example Digit A 1st 3 B 2nd 8 C 3rd 1 D 4th 4 E 5th 4 F 6th 6 After substitution your expression will be similar to this (( 3 + 8) / 1) * ((4-4)/6)-2). Draw a rooted tree that represents your expression. [3 marks] What is the prefix form of this expression. What is the value of the prefix expression obtained in step 2 above?
PROGRAMMING PROBLEM The inventory of a shoe store lists shoes by stock number. With each stock number, there is associated a style number in the range of 0 to 50, the number of pairs in each size (sizes range from 3 to 14) and a price. A program is to be written to keep track of the inventory. The user is given the following choices: enter a new record, display a record, change the price of the stock item, or change the number on hand. When specifying a record the user may give either the stock number, or the style number. The array index can be used as a stock number. If the user decides to change the stock on hand, the program should ask which sizes will have their stock on hand changed. The program should be designed to run indefinitely, keeping track of changed in stock.
The 24-point card game involves picking any four cards from 52 cards, as shown in Figure 10.20. Note that the jokers are excluded. Each card represents a number. An ace, king, queen, and jack represent 1, 13, 12, and 11, respectively. Enter an expression that uses the four numbers from the four selected cards. Each card number can be used only once in each expression, and each card must be used. You can use the operators ( *, and /) and parentheses in the expression. The expression must evaluate to 24. After entering the expression, click the Verify button to check whether the numbers in the expression are currently selected and whether the result of the expression is correct. Display the verification in a dialog box. You can click the Refresh button to get another set of four cards. Assume thatimages are stored in files named 1.gif, 2.gif, ..., 52.gif, in the order of spades, hearts, diamonds, and clubs. So, the first 13 images are for spades 1, 2, 3, ..., and 13.
