Hello you guys, I am a newbie in Python and I'm also studying more about Python.
I have a small assignment, I have an array of name students and I want to order them by alphabet ascending. Like this:
students = ["Hannah", "Anna", "Trump Hazon", "Jonh Buddy", "Red Bull"]
students = students.sort()
print(students[0])
print(students[1])
print(students[2])
But I get an exception TypeError: 'NoneType' object is not subscriptable when I am trying to run code above.
Traceback (most recent call last):
File "main.py", line 3, in <module>
print(students[1])
TypeError: 'NoneType' object is not subscriptable
I'm using Python version 3.8.2.
Anyone can explain it to me? How can I solve it?
Thanks for any response.

The error TypeError: 'NoneType' object is not subscriptable throw when your variable is an object but you access it as an array.
So to sort an array you can change
students = students.sort()tostudents.sort(). See an example below:students = ["Hannah", "Anna", "Trump Hazon", "Jonh Buddy", "Red Bull"] students.sort() print(students[0]) print(students[1]) print(students[2])#OUTPUT
Anna Hannah Jonh Buddy
