Question
What will be the output of the following Python code?def foo(k): k = [1]q = [0]foo(q)print(q)
Solution
The output of the Python code will be [0].
Here's the step by step explanation:
-
A list
qis defined with one element: 0. -
The function
foo(k)is called withqas the argument. Inside the function,kis assigned a new list [1]. However, this doesn't affectqbecause lists are passed by reference in Python, meaning thatkis a new reference to the same list, not a reference toqitself. When you assign a new list tok,qremains unchanged. -
print(q)is called, which prints the original listq([0]).
