List 1:

concept 1:
check list and find the item no

packages = ["Letter", "Box", "Parcel"]
print(packages)
item=packages[1] #here the index 1 refers to item box.
print(item)

#Output
['Letter', 'Box', 'Parcel']
Box

Concept 2:

packages = ["Letter", "Box", "Parcel"]
print(packages)
#add an item in the list
packages.append("special delivery")
print(packages)

#Output
['Letter', 'Box', 'Parcel']
['Letter', 'Box', 'Parcel', 'special delivery']

Concept 3:

packages = ["Letter", "Box", "Fragile Box", "Parcel", 
"Special Delivery"]
last_package = packages.pop() 
#removes last item in the list
print(packages)
packages.remove("Box") #removes item box
print(packages)

#Output
['Letter', 'Box', 'Fragile Box', 'Parcel']
['Letter', 'Fragile Box', 'Parcel']

Concept 4:

packages = ["Letter", "Box", "Fragile Box", "Parcel"]
position = packages.index("Parcel")
print(position)
packages.sort() # arrange alphabetical order
print(packages)
packages.reverse()
print(packages)

#Output
3
['Box', 'Fragile Box', 'Letter', 'Parcel']
['Parcel', 'Letter', 'Fragile Box', 'Box']
