Lecture "Organising information: ordered structures", exercise 1

[essepuntato]

Write a sequence of instructions in Python so as to create a list with the following elements ordered alphabetically: "​Harry"​, "​Draco"​, "​Hermione"​, ​"​Ron"​, "​Severus"​.

# METHOD 1: alphabetize manually and add apend them already in alphabetical order

harrypotter_list0 = list()  # this creates a new list

harrypotter_list0.append("Draco")
harrypotter_list0.append("Harry")
harrypotter_list0.append("Hermione")
harrypotter_list0.append("Ron")
harrypotter_list0.append("Severus")

# check our list looks right
print(harrypotter_list0)


# METHOD 2: first create the list without regard the alphabetization and alphabetize later
harrypotter_list = list()  # this creates a new list

harrypotter_list.append("Harry")
harrypotter_list.append("Draco")
harrypotter_list.append("Hermione")
harrypotter_list.append("Ron")
harrypotter_list.append("Severus")
# so far harrypotter_list contains:
# list([ "Harry", "Draco", "Hermione", "Ron", "Severus"])

# now, find a way of sorting alphabetically (used Google to find the command)
harrypotter_list.sort()

# check our list looks right
print(harrypotter_list)

[bluebell94]

protagonist_list ={"Harry","Draco","Hermione","Ron","Severus"}

	1	protagonist_list=list()
2	protagonist_list.append("Harry")
3	protagonist_list.append("Draco")
4	protagonist_list.append("Hermione")
5	protagonist_list.append("Ron")
6	protagonist_list.append("Severus")
7	protagonist_list.sort()
8	print (protagonist_list)

I was thinking also about using the commands >, < in order to put the names in alphabetical order, However, it seems as a too long and much more complex process, especially when the command "sort" is available and has the same functions.

Output: ['Draco', 'Harry', 'Hermione', 'Ron', 'Severus']

potter_list.append("Ron")
potter_list.append("Harry")
potter_list.append("Severus")
potter_list.sort() #I've found that built-in function named _sort_, 
don't know if it's considered cheating for the sake of the exercise :)
I suppose it's also possible to write just one line and put strings inside the sort bracket.
print(potter_list)

"​Harry"​, "​Draco"​, "​Hermione"​, ​"​Ron"​, "​Severus"

dislike_harrypotter = list()
dislike_harrypotter.append ("draco")
dislike_harrypotter.append ("Harry")
dislike_harrypotter.append ("Hermione")
dislike_harrypotter.append ("Ron")
dislike_harrypotter.append ("Severus")

print dislike_harrypotter

With the use of "sort" built-in function

dislike_harrypotter = list()
dislike_harrypotter.append("​Harry"​, "​Draco"​, "​Hermione"​, ​"​Ron"​, "​Severus")
dislike_harrypotter.sort
dislike_harrypotter("Draco","Harry","Hermione","Ron","severus")
