Write python expressions corresponding to these statements:

2.22 write an expression involving string s containing the last and first name of a person— separated by a blank space—that evaluates to the person’s initials. if the string contained my first and last name, the expression would evaluate to 'lp'.

2.23 the range of a list of numbers is the largest difference between any two numbers in the list. write a python expression that computes the range of a list of numbers lst. if the list lst is, say, [3, 7, -2, 12], the expression should evaluate to 14 (the difference between 12 and -2).

2.24 write the relevant python expression or statement, involving a list of numbers lst and using list operators and methods for these specifications:

(a) an expression that evaluates to the index of the middle element of lst

(b) an expression that evaluates to the middle element of lst

(c) a statement that sorts the list lst in descending order

(d) a statement that removes the first number of list lst and puts it at the end

This assignment continues work on the online booking facility introduced at the end of chapter- 10. the work will be continued in the assignments for chapters 14 and 15 (a) assume that you will produce your online booking facility using an agile approach. i. suggest the kind of user research you would like to conduct for your product before iteration cycles begin. ii prioritize the requirements for your product according to business value, i. e which requirements are likely to provide the greatest business benefit, and sketch out the ux design work you would expect to undertake during the first four iteration cycles, i. e. cycle 0, and cycles 1 to 3. (b) using one of the mockup tools introduced above, generate a mockup of your product's landing page, as developed in the assignment for chapter-11 (c) using one of the patterns websites listed previously, identify suitable interaction patterns for elements of your product, and develop a software-based prototype that incorporates all the feedback and the results of the user experience mapping achieved at the end of chapter-11. if you do not have experience in using any of these, create a few html web pages to represent the basic structure of your website
