What do these lines print?>>> a = [1, 2, 3, 4]>>> a[2] = 10>>> a[1, 2, 10, 4][1, 2, 10, 10][1, 10, 3, 4][1, 2, 3, 4]
Question
What do these lines print?
>>> a = [1, 2, 3, 4]
>>> a[2] = 10
>>> a
[1, 2, 10, 4]
The final list is:
[1, 2, 10, 4]
Solution
The provided text seems to be a bit jumbled, but it appears to be in Python. Here's a step-by-step explanation of what it's trying to do:
-
a = [1, 2, 3, 4]
- This line is creating a lista
with four elements: 1, 2, 3, and 4. -
a[2] = 10
- This line is changing the third element of the lista
(Python uses 0-based indexing, soa[2]
refers to the third element) to 10. So now,a
is[1, 2, 10, 4]
.
The rest of the lines are not valid Python code. If you're trying to print the list a
, you would use the print(a)
command. If you're trying to access multiple elements of the list, you would need to do so individually (e.g., a[0]
, a[1]
, etc.).
If you're trying to create new lists, you would need to do so like this: b = [1, 2, 10, 4]
.
Without more context or correct syntax, it's hard to determine exactly what the remaining lines are trying to do.
