Are the python cuts right?

I just started studying python and faced a problem... There's a list of 100 and more elements I need to pick from 1 to 6 in 10 tons.
mylist=list(range(200)) x = milist[0:6:10] print(x) выводит [0]
How to write correctly using [:

One cut here, don't bother  they'll have to be combined  separate cuts for chiel ending on one, then two, etc.
The balance of separation (in nontribal cells) may be used  such a solution will be more elegant:
res = [x for x in mylist if x % 10 < 7]
If there are any negative numbers on your list, then you can do it, it'll work for both positive and negative:
res = [x for x in mylist if abs(x) % 10 < 7]
a little perverse that uses
sum()
and cuts:res = sorted(sum((mylist[i:len(mylist):10] for i in range(7)), []))
