Why does sorting of a list work outside of, but not within the print function in Python?

I have a list in Python which I want to sort by alphabet.
If I do this directly within the the print() function, it yields "None", while it works fine if I sort it first and then print it. Here is the reproducible code:

def main():
    l = ["Tina", "Alice"]
    print(l.sort())
    # yields "None"
    
    l.sort()
    print(l)
    # yields ["Alice", "Tina"]
    
if __name__ == "__main__":
    main()

Can someone explain to me what the difference is in the background for Python? Some other operations like adding numbers etc. work fine within the print() function. Thanks!

>Solution :

It’s because sort function returns None, it modifies the list itself.

There are sorted function too, which doesn’t modify list but returns new one

print(sorted(l))
