Question

Answer 1

You should use print(sorted(a)).

a.sort() just executes the sorting, it does not return any value, that's why None is printed.

Answer 3

@Keep in mind. Your answer wouldnt have gotten as much exposure as Kubas as it was a good 10 hours after the question was asked.

That said, search likestorms here in the q and a.

Answer 4

On top what @Keep wrote, you may try the below to see what the difference is between .sort() and sorted()

a=[4,2,6,1]
print(a)
a.sort()
print(a)
print()

b=[4,2,6,1]
print(b)
print(sorted(b))

As you can see .sort does its job in-place, but returns None. sorted(b) returns the sorted list, but does not change the list itself.

Answer 5

Yes right sir I get it thanks.

Answer 6

You should do like this.

a=[4,2,6,1]
a.sort()
print (a)
Now it will print the sorted no
