What is "[...]" in list ?Why the second output doesn't have double list ?I know that a and b share same id but, Why this is happening?
a = [1, 2, 3]
b =a
b.append(4)
print(a)
output :[1, 2, 3, 4]
a.append(b)
print(b)
output :[1, 2, 3, 4, [...]]#what happend here ?
Okay i don't know that this is best answer or not Please do correct me if i am wrong.
Try This :
print(b[4][4]) # you can add as many [4] you want and i used [4] because it isthe position of [...] .
The output will be same **Output:[1, 2, 3, 4, [...]] **
So i tried getting address of all 'b' as well as 'b[4]' , 'b[4][4]' ......
using:
print(id(b))
print(id(b[4]))
print(id(b[4][4]))
## All these will return the same address.
So, the list inside list is the same list (a or b) and it continues, this is why you are getting those '...'
