Python Question / Quiz; What is the output of the following Python code, and why? Comment your answers below!

@PythonPr Answer: (A) 20 The code demonstrates how variable assignment works with mutable objects (like lists) in Python. a = [10, 20, 30] creates a list object [10, 20, 30] and assigns the variable a to reference this object in memory. b = a does not create a new list.

@PythonPr Answer: A) 20 Step by step: › a = [10, 20, 30] creates list › b = a makes b point to same list › a = [40, 50] reassigns a to NEW list (b unchanged!) › b still points to [10, 20, 30] › b[1] = 20 For beginners: Reassignment breaks the connection between variables!

@PythonPr Output A) 20 b = a makes b reference the original list [10, 20, 30]. Reassigning a to [40, 50] creates a new list and doesn’t affect b. So b[1] is still 20.

@PythonPr A) 20 b = a makes b reference the original list [10, 20, 30]. When a is later reassigned to a new list [40, 50], b still points to the old list. So b[1] is 20.

@PythonPr A: 20

@PythonPr A. 20

@PythonPr @grok ?

@PythonPr B) 40

@PythonPr A) 20

@PythonPr 20

@PythonPr A

@PythonPr It's 20, because list a now is another list in another memory address while b points to the older one.

@PythonPr 20

@PythonPr A

@PythonPr b=a True b index 1=20

@PythonPr 20

@PythonPr The ouput will be : AWESOME!
