# How to replace a list with a range value.

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here

temp = the_list.pop(3) the_list.insert(0,temp) del the_list[4] the_list.remove('a') del the_list[3]

## the_list = the_list.extend(range(1,21))

I am not sure of how to extend a range of 1-20 to the_list.

No need to create a separate list to add 4 to 20 to the_list. Just do:

```the_list.extend(range(4, 21))
```

I read the question more carefully and was able to pass the test. The values 1-20 have to exist in the list, since the previous lines of code leave us with 1,2,3 in the list we can extend with range(4,21) !

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here

temp = the_list.pop(3) the_list.insert(0,temp) del the_list[4] print(the_list) the_list.remove('a') del the_list[3] print(the_list)

new_list = range(4,21) the_list.extend(new_list) print(the_list)

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here

temp = the_list.pop(3) the_list.insert(0,temp) del the_list[4] print(the_list) the_list.remove('a') print(the_list)

for i in the_list: the_list.pop(i)

new_list = range(1,20) the_list.extend(new_list)
