Hi Haasini!

This passes:

my_list = []

for val in range(0, 10):
    my_list.append(val)

Keep in mind a range start value by default is 0, so this passes also:

my_list = []

for val in range(10):
    my_list.append(val)

Also, in the real world, val could be any variable name, such as i or 'element' or even 'el', but var was what the instructions were suggesting, so I used that.

Also, the instructions don't ask you to print anything - so don't - although, again, in the real world, it would probably make sense to do so, especially for testing purposes.

I hope that helps.

Stay safe and happy coding!
