What will be the output of the following Python code snippet?a=[1, 4, 3, 5, 2]b=[3, 1, 5, 2, 4]a==bset(a)==set(b)
Question
What will be the output of the following Python code snippet?
a = [1, 4, 3, 5, 2]
b = [3, 1, 5, 2, 4]
a == b
set(a) == set(b)
Solution
The output of the Python code snippet will be:
False True
Here's the step by step explanation:
-
The first line of code
a==b
compares the two listsa
andb
. In Python, two lists are considered equal if they both have the same length and each pair of elements at the same index in both lists are equal. In this case, although listsa
andb
have the same elements, the order of the elements is different. Therefore,a
is not equal tob
, and the output ofa==b
isFalse
. -
The second line of code
set(a)==set(b)
compares the two sets created from listsa
andb
. A set in Python is an unordered collection of unique elements. When a list is converted to a set, the order of elements is lost and duplicate elements are removed. Therefore,set(a)
andset(b)
are equal because they both contain the same elements, regardless of the order in the original lists. Hence, the output ofset(a)==set(b)
isTrue
.
