Question
What will be the output of the following Python code?
def foo(k):
k = [1]
q = [0]
foo(q)
print(q)
- [0]
- [1]
- [1, 0]
- [0, 1]
Solution
The output of the given Python code will be [0].
Here's the step by step explanation:
-
A list
q
is defined with a single element 0. -
The function
foo(k)
is called withq
as the argument. Inside the function,k
is assigned a new list [1]. However, this doesn't affectq
because lists are passed by reference in Python, and the function is creating a new referencek
instead of modifying the original referenceq
. -
After the function call,
q
is printed, which is still [0] as it was not modified by the function.
