As others have already posted, changing the value of 'value' has
nothing to do with the list variable 'numbers'. To modify the list in
place, you need to access its members by index. The following code
does this:
numbers = [1,2,3]
for i in range(len(numbers)):
numbers[i] *= 2
print numbers

Above, you are modifying "value", not the item in the list
>>> numbers = [1, 2, 3]
>>> for x in range(len(numbers)):
... num

The following code:
numbers = [1, 2, 3]
for value in numbers:
value *= 2
print numbers
results in the following output:
[1, 2, 3]
The intent of the code was to produce this output:
[2, 4, 6]
What is the reason for the output produced?
What code should be used to obtain the desired outpu
