Answer #1

Answer: B,C,D

A. Incorrect
In python there won't be any type declaration for variables as declared in c

int x = File <ipython-input-1-e1416c13da13>, line 1 int x = 3 A SyntaxError: invalid syntax

B. Correct

In the below example implementation
x variable takes the string value 'test'
later it takes int value 3
while both are in the same function.
Python being an interpreter always chooses the latest value of variable so value of x is 3

def main(): X = test X = 3 print(x) main() 3

C. Correct
The variable x in the below implementation takes the list values
def main(): x = [3,22,3] print(x) main() O [3, 22, 3]

D. Correct

The variable x takes the value of a type (3,3)
def main(): X = (3,33) print(x, type(xD) main() (3, 33) <class tuple>
