How do I append a value to a list?

I thought I was supposed to make a list value from 0-10 but I had to append values. What does that mean?

iterating_ranges.py
my_list = ['I', 'say', 'Python', 'is', 'a', 'really', 'nice', 'computer', 'programming', 'course', 'man']
for i in range (0, 10, 1):
    my_list.append()

Hi ks13!

"I thought I was supposed to make a list value from 0-10 but I had to append values. What does that mean?"

You don't need to make values and enter them into my_list.

The challenge asks for a for loop that iterates over a range with a stop value of 10, and a start value of 0. Then it wants you to append each value in the loop to my_list (using the syntax my_list.append(val)).

Your for loop looks good. You only need to remove the values you put in my_list & adjust some syntax: Like this:

my_list = []
#we want my_list to be empty, because the lines below will add/append values to it
for val in range (0, 10, 1):
#the line above is going to loop through each value in the range from 0-9
    my_list.append()
     #when you append to a list, you need to put *what* you're appending in the parentheses.

Let me know if you have further questions. I hope this helped!
