I'm having trouble using list functions. My goal is to iterate 0_9 counted by 2s evenly, and 9_15 by 2s odds.
Ive tried range and set, plus min max. Im not understanding the syntax.

Jay Matthews [*range(9, 16, 2)] would be a faster alternative though.

* is an "all arguement" factor rite?

Aaron Yup, the asterisk in my code 'breaks down the iterator' by passing all the values retuned by it as separate entities to the list, one by one. I won't call it 'arguments', though.

So it individualizes the factors

Do i use brackets for functions regarding list, and, if im calling a functiin am I to use the same parameter identifiers as the data set.

a_list = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]
a_list = a_list.range(9,16,2)
print(a_list)
First the asterix is called invalid syntax, then I get object list has no attribute range.
Now I'm trying to just count the list by twos before I do the original objective.
What am I doing wrong?

Slicen dicen it is then

Thats my prob. Im using commas not colons

It calls colons synerr

a=range(0,10,2)
b=list(a)
c=range(9,16,2)
d=list(c)
print(b)
print(d)
[0,2,4,6,8]
[9,11,13,15]
Print(b+c) == can only concatenate list (not "range") to list.

Print(b.append(d))==none

Im trying to count evens by twos 0-10 and odds by twos 9_15 but I want to do it in one list.
+ 1
So what ive learned is range is a data type and I cant convert rang in the os to a list because list conversion only applies to tuples and strings, which is why I get back none when i run even.extend(odd)
Which should concatenate the 'lists'.
And an error when i insert odd at14,15,or16. If Im wrong let me know

Aaron Now I see what you're really intending for. Here's a possible solution:
merged_list = list(x for x in list if not x & 1) + list(x for x in list if x & 1)
# Hope this helps
# Happy coding!

Ive thought about seperating the list and putting it back together but I dont get that either. I think i dont understand how to assign the function

How do I range.
List.range(0,10,2) ?

K thanx

Aaron Could you please elaborate on your most recent question?

Aaron The list class has no such method called 'range'. You may go with slicing instead.

[9:16:2] - Doesn't this work?
