a,b,*c?

Question

What is the output?
a,b,*c=[x for x in range (0,12,3)]
print (*c)
Solution: 6 9

I know were asking Python to go from 0 to 12 by 3.
Then take every third number *3?
So the index is: 0-1-2-3-4-5-6-7-8-9-10-11-12
Every third number is (2*3=6), (3*3=9), so far so good.
Why doesnt Python also print (8*3=24) and (11*3=33)?

Any help appreciated:)

Answer 1

The range function works a little differently than how you described it. What it does is start by 0, then move up by 3 until it reaches 12 (excluding it though). This leaves the array to be 0, 3, 6, and 9. Because variables a and b took the values 0 and 3 and c takes the rest (because of the *), the value of c becomes 6 and 9.

No problem at all d:

Answer 3

No need to apologize haha, programming can definitely be confusing at times :)

The range function takes 3 parameters, a lower range, upper range, and step. As I mentioned in my previous reply, because the range is set from 0 to 12 and the step is 3, the first element will be 0 with each element following it be 3 steps up from the previous one. This leaves with an array of [0,3,6,9] (upper range is always left out).

Then, the variables a, b, and c are set to different values of the list. a is set to the first element (0), b is set to the second element (3), and because c has the asterisk * before it, it is set to be a list of all remaining elements (although * can be used for multiplication, in this case it's used to indicate the rest of the element within the list). This leaves c to be [6,9] which is what ends up getting printed

Answer 4

Faisal! Thanks so much! Now I get it (I will review the unit on ranges and lists)👍🏻

Answer 5

Sorry! One more question! Why would it be "6" and "9"? Shouldnt it be "6" (3*3 is 9) and "15 (5*3 is 15)?

Sorry, Im totally lost:(.

Answer 6

Also, I thught the * was a multiplication symbol? So 2 times 3, which is 6?

Answer 7

Thanks for the help, Faisal:).
