Question
What will be the output of the following Python code?
l = [[1, 2, 3], [4, 5, 6]]
for i in range(len(l)):
for j in range(len(l[i])):
l[i][j] += 10
print(l)
Solution
The output of the given Python code will be:
[[11, 12, 13], [14, 15, 16]]
Here's the step-by-step explanation:
-
The given code defines a list of lists,
l, with two sublists: [1, 2, 3] and [4, 5, 6]. -
It then enters a nested loop where it iterates over each element in each sublist.
-
For each element, it adds 10 (
l[i][j]+=10). -
Finally, it prints the modified list
l.
So, the original list l:
[[1, 2, 3], [4, 5, 6]]
becomes:
[[11, 12, 13], [14, 15, 16]]
