Question

What does c=a+b[1] mean by b[1]?

Answer 1

if b is a list then it's second, because array/list index starts with zero
so...
if b = [7,5,3,6]
b[0] gives 7(that is our first element in b)
b[1] gives 5(which is our second element in b)

Answer 2

The second element of b

Answer 3

The second element of b

Answer 4

It would always be a good and helpful idea, if the question will be completed by the related code. Thanks!

Answer 5

Here a is variable and b is list
b[1] means second element of list
And a + b[1] means they are adding it or concatinating it
For ex
a = 5
b = [1, 2, 3, 4, 5.....]
here, b[0] = 0 (because index start with 0)
So, b[1] = 2
And,
a + b[1] = 5 + 2 = 7
Hope You understood.

Answer 6

thanks to answer

Answer 7

The second element of b

Answer 8

why b[1] is second element of b?

Answer 9

D구산중학교원인성 becouse b is list so that indexing is start from 0 that is , first element has index 0 , second element has index 1 , third element has index 2 and so on....

Answer 10

If b is an array then,
It's first position can be called as b[0]
For ex.
If array b has value [2,3,4]
Then b[0] is 2 and it runs same through array like
b[1] must be 3 in this case
and same b[2] will be 4
