Python
Problem A [50 Marks]: Solve the following questions using python only. A-1. Create a list L1 containing numbers from 15 to 24 (24 exclusive), using LIST COMPREHENSION (do not use list function or usual FOR loop). Sort the list in ascending order. Create a new list L2 from L1 using LIST COMPREHENSION, where the elements of L1 and L2 are related as follows: L2=[] for i,e in enumerate(L1): if e\%2==1: if e>i: L2. append (e+i) else: L2. append (ei) A-2. Let B=[61,25,36,21,58,101,254,200] be a list. Apply the following function (x2 (x2))//50 on each element of B. Don't use FOR loop! A-3. Consider the following text: (4 marks) "dvoxlnv gl rhv 291 rg droo yv z ivzoob rmgvivhgrmt xlfihv, wl blfi yvhg zmw ivnvnyvi gszg mlgsrmt yvggvi gszm gsv sziw dlip." a. Create a list of words (all contiguous characters) in the order of their appearance. Remove newline characters (if any) from the list. (8 marks) A-4. Consider the following texts: Text1= "dvoxlnv gl rhv 291 rg droo yv z ivzoob rmgvivhgrmt xlfihv, wl blfi yvhg zmw ivnvnyvi gszg mlgsrmt yvggvi gszm gsv sziw dlip, gsv xlfihv xlmgzrm 4 slnvdliph" Text2= "welcome to ise 291 it will be a really interesting course, do your best and remember that nothing better than the hard work, the course contain 4 homeworks" a. Create a dictionary where words (all contiguous characters) from Text1 are keys, and words from Text2 are values. b. Is there any difference in the total number of words in Text1 and the total number of keys in the above dictionary? If yes, then explain the reason for the difference. (10 marks) A-5. A-5: Create a random integer numpy two-dimensional array of size 59, where the integer values range from 1 to 100 (100 inclusive). Set the random generator seed to be 26 . Call the array as S. Print the dimensions, shape, and size of S. A-6. Print alternate columns starting from column indexed 3 and all the rows of S. (4 marks) (3 marks) A-7. Create a new numpy array M1 that contains third-row elements of S in order of column 8, then 5 , then 3, then 1. Similarly, create a new array M2 that contains fourth-row elements in order of column 9 , then column 7 , then column 2 , then 8. (4 marks) A-8. Create a new one-dimensional array by joining M1 and M2. Create another new two-dimensional array by vertically joining M2 below M1. (4 marks) A-9. Create a copy of S, say P. Sort the elements in the even columns of P (that is, in each even column, the smallest element is in the first row, and the largest in the last row). Print both S and P. (4 marks) A-10. Add the following array [1,2,3,4,5,6,7,8,9] to all the rows of P. Print all the elements of updated P that are strictly between 20 and 60
