a = [[[[8, 9, 0]], 8]]

Question

What is the output of this code?
a = [[[[8, 9, 0]], 8]]
print(len(a))
Output: 1

It's a list? But 8,9,0 is nested? So aren't there 2 items in the list? Thanks for any help:).

Answer 1

a=[[...]]
b=[[[[[[...]]]]]]
len(a)==len(b)

a=[
[[[8,9,0]],8]
];
len(a)=1;

len(a[0])=2;
👇
1. a[0][0]=[[8,9,0]],
2. a[0][1]=8;

len(a[0][0])=1;
👇
1. a[0][0][0]=[8,9,0];

len(a[0][0][0])=3;
👇
1. a[0][0][0][0]=8;
2. a[0][0][0][1]=9;
3. a[0][0][0][2]=0;

Answer 2

Thanks Bi, Vas and Jay.

Maybe it's symantics, but a list with three elements sounds like the length of the list should be 3?

Either way, I'll study more and thanks for your help:).
