Question
![You are given a file which has an Australian state name and a university name in each line.
You can view the file as follows. DO NOT CHANGE the content of the uni.txt (otherwise you
will have to press the triple dot button at the top-right and then "Reset to Scaffold").

Write a program sorter.py that 1) reads a command line argument containing the file to
open, 2) opens and reads the file, 3) extracts each Australian state (not the university), i.e. the
first word token in each line, and 4) sorts the states in alphabetical order. You may assume
that each state is one word long. Furthermore, make sure to only record the names of unique
states - so do not record any state twice.
HINT: use the in keyword. E.g.
▸ Run
1 ls = [1,
2 if 4 in ls:
3
4 elif 4 not in ls:
2, 3]
print("4 is in list")
5
print("4 is NOT in list")
PYTHON
You MUST use open(), read(), split(), sort(), print() methods, and for loops.
Make sure you handle the case where the file cannot be found (use a try ... except block)!
*In order to sort the list, you can use list.sort() method. For example, the list items can be
sorted by using the following codes:
► Run
1 names = ['caren', 'annie', 'henry']
2 #listname.sort()
3 names.sort()
4 print(names)
PYTHON
Your program should output the following.
1) When the file (e.g. uni.txt) is found:
[user@sahara ~]$ python3 sorter.py uni.txt
['ACT', 'NSW', 'QLD', 'SA', 'VIC', 'WA']
2) When the file (e.g. does_not_exist.txt) is NOT found:
[user@sahara ~]$ python3 sorter.py does_not_exist.txt
There is no such file](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb4d9d51c-cee3-4855-8494-55e8cc009ab5%2Fed3e6341-f2aa-4fb6-b90c-5f65415c02db%2Ftz3dy9o_processed.png&w=3840&q=75)
