show: Lists the items that the wizard is currently carrying along with the index for each item and the weight of that item. See sample runs below. As shown in the sample this function also prints the total weight of the items along with the max weight limit of 100 lbs. Hint: You can use the sum function in Python to calculate the sum of weights. E.g. sum(weights) will return the sum of all the items in the weights list. grab_item: Add a new item while enforcing the following policy: There is a limit of 4 on the number of items the wizard can carry and limit of 100 lbs on the total weight the wizard can carry. So specifically, if the wizard is already carrying 4 items, print message that “You can't carry anymore items. Drop something first.” And return out of the function. Otherwise prompt the user for the name and the weight of the new item. Next check whether with the addition of the new item, the total weight will exceed the limit of 100 lbs. If so, print a message saying weight limit will be exceeded, so cannot add the new item and return out of the function. Otherwise add the new name and weight to the two lists. See Sample runs below. Hint: You can use the sum function in Python to calculate the sum of weights. E.g. sum(weights) will return the sum of all the items in the weights list. edit_item: Allow the user to update (only) the name of one of the items. Prompt the user for the index of the item to be edited. Validate that the index is between 1 and current count of items. If invalid, print a message to that effect and exit. Otherwise prompt the user for the new name and update the name of the item. Print that the item was updated successfully. See Sample runs below. drop_item: Prompt the user for the index of the item to be dropped. Validate that the index is between 1 and current count of items. Remove the item from both the lists.
