  # You visited a restaurant called CodeWithHarry, and the food items in that restaurant are sorted, based on their amount of calories. You have to reserve this list of food items containing calories. # # You have to use the following three methods to reserve a list: # # Inbuild method of python # List name [::-1] slicing trick # Swapping the first element with the last one and second element with second last one and so on like, # [6 7 8 34 5] -> [5 34 8 7 6] # # Input: # Take a list as an input from the user # # [5, 4, 1] # # Output: # [1, 4, 5] # # [1, 4, 5] # # [1, 4, 5] # # All three methods give the same results! print ( "Welcome To Our Program \n " "Foods and Calories" ) # Take the size of the list from the user print ( "Enter the numbers of the list one by one \n " ) size = int ( input ( "Enter size of list \n " )) # Initialize a blank list mylist = [] # Take the input from the user one by one for i in range (size): mylist.app...
