I know this is a simple code, but somehow I kind of wonder why it is so…

my\_list = []

for i in range (5):  
my\_list.append (i + 1)

print(my\_list)

[1, 2, 3, 4, 5]

I was thinking of [2,3,4,5,6]. Because it is i+1 for each number from 1 to 5…  
Thank you in advance for the explanation.

The `range()` function yields values which start from `0`, not `1`, by  
default. This matches the use of indices, which also count from `0`.

Try this:

```
 print(list(range(5)))

```

`range(5)` produces a sequence of 5 integers starting with `0`, not `1`

By providing the parameter `5` you’re saying: give me 5 numbers, starting from `0` and stopping when you get to `5`.

To append the numbers 1 to 5 you’d do this:

```py
my_list = []

for i in range(1, 6):
    my_list.append(i)

print(my_list)

```

This way the range gives you all the numbers from start to stop, but does not include stop. This is called a “half open range” in computing.

Oh, starts from 0. I may have confused it again. Thank you for the reply!

These are also equivalent:

```py
# Convert an iterable to a list
my_list = list(range(1, 6))

# Use a list comprehension
my_list = [i for i in range(1, 6)]

```
