FILES 1) Print every OTHER line of a file. 2) Make a file that is just a bunch of numbers, one per line. Write a program that adds them up. LISTS 1) Given the list l=[1,12,3,12,5,6,12] count the number of 12's. 2) Compute the sum of the not-12s. You should get 15. 2) Give the list above, make a list of the non-12 elements. You should get [1,3,5,6] LOOPS 1) Make a program that prints this: 256,128,64,32,16,8,4,2,1 2) Make a loop that prints 1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5 ... (forever)
