What is the mistake in this code?

Question

It gives output as none...

queue = ['John', 'Amy', 'Bob', 'Adam']
a=input()
print(queue.append(a))

Answer 1

What are you trying to print? Input or queue?

queue.append( a )
print( queue )

Answer 2

Riya ,

here a short explanation why your code prints *None*.

<list>.append() is adding a new element at the end of the list. this is done in place, this means no new list is created. all functions that are working in place do not give a return value. in this case *None* is printed.

Well u cant access a variable that you deklarate just in the moment, like my foreposters already said: first apply the value THAN read the value.
