Why I cannot use append method in python?

Question

Why I cannot write it:

cubes.append(9)
print(cubes)

as

print(cubes.append(9)

Answer 1

Because append method doesn't returns a new list or anything else,it modifies original list .

Answer 2

The output will be None! Because append() function does not return anything ,

Correct way to do

a = []
a.append(2)
print(a)

Output - [2]

All the best!

Answer 3

Or if you want to append the element inside the "print" statement so it will print the list right away like what you are trying to do.

print( list + [elements] )

print( cubes + [9] )

# You can append multiple elements.

print( cubes + [9, 27, 81] )

Or you can just follow their answers if you want to use append method.
