[FIXED] "IndexError: list index out of range" in very simple 3 lines of Python code

Issue

I am a newbie to the programming and trying to understand how things work. I couldn't get my program to iterate through numpy.array normally, so I decided to try one level simple iteration through list. But still it wouldn't work! The code is as follows:

my_list = [1, 2, 3, 4, 5, 6, 7]
for i in my_list:
    print(my_list[i])

The output is:

So it doesn't take the my_list[0] index of some reason and comes out of range. Could you please help me to understand why?

Solution

It's not clear what exactly you're trying to do. When you iterate over an iterable like a list with

for i in my_list:

each i is each member of the list, not the index of the member of the list. So, in your case, if you want to print each member of the list, use

for i in my_list:
    print(i)

Think about it: what if the 3rd member of the list was 9, for example? Your code would be trying to print my_list[9], which doesn't exist.
