Why am I getting

[2, 4, 6, 8, 10, 12, 0, 4, 8, 12, 16, 20]

when I want to only get

[2, 4, 6, 8, 10, 12] ?

Thanks for your help in advance.

In this problem, you will need to write code to manipulate a list of integers. [16]: \# Define a list of integers numbers=[1,2,3,4,5,6] First, you will iterate through the list and double each integer so the the list (still named "numbers") is now: [2,4,6,8,10,12] [n [17]: M #Fillinthecodetodoubleeachelementinthelistforiinrange(len(numbers)):numbers.append(i2)numbers=[i*2foriinnumbers] [n [18]: print(numbers)#thisshouldshow[2,4,6,8,10,12][2,4,6,8,10,12,0,4,8,12,16,20]
