Question 65
Correct Answer: B
The code attempts to print the result of adding the return values of the unclear function for inputs 1 and 2. The function unclear(x) is defined to return 0 for odd numbers but does not specify a return value for even numbers, leading to an implicit return of None. Therefore, unclear(1) returns 0, and unclear(2) returns None. The code then tries to add 0 and None, which results in a TypeError because Python cannot add an integer and NoneType. Additionally, there is a syntax error in the print statement due to the misplaced parenthesis. However, since the runtime exception has a higher precedence in identifying the behavior, the correct answer is that the code will cause a runtime exception.
Discussion
AvidulamOption: B
the answer is B, print has syntax error
nmgOption: B
B 1 returns int 2 return None you can't add them
Divya1008Option: B
Option B. Executing the program gives the following output: print(unclear(1)+unclear(2)) TypeError: unsupported operand type(s) for +: 'int' and 'NoneTy pe'

The expected behavior of the given code is as follows: The function unclear(x) takes an integer x as input and checks if it is an odd number. If x is odd, the function returns 0, otherwise it does not return anything and continues to execute. In the code, the function unclear(1) is called first with the argument 1. Since 1 is an odd number, the function returns 0. Then, the function unclear(2) is called with the argument 2. Since 2 is an even number, the function does not return anything and continues to execute. Finally, the result of unclear(1) + unclear(2) is evaluated. Since unclear(1) returns 0 and unclear(2) does not return anything, the result of unclear(1) + unclear(2) is 0 + None, which will raise a TypeError at runtime. Therefore, the expected behavior of the code is to print an error message, specifically a TypeError.

Where does it check if x is odd or even number?
Janpcap123Option: B
if the ) after print the answer is B cause a runtime error, if the print statement is syntactically correct the answer would be: TypeError: unsupported operand type(s) for +: 'int' and 'NoneType' TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'
Damon54Option: B
What is the expected output of the following code ? def unclear (x): if x % 2 == 1: return 0 print ( unclear (1) + unclear (2)) So, the provided code will result in a type error during execution due to the sum of values of different types. If you want to get a valid result, you should modify the unclear function to return a value other than None when x is even, for example, returning 1 in that case.
Ello2023Option: B
B '==' has space in between print brackets starts with end bracket ')'
macxszOption: B
B. cause a runtime exception
rocky48Option: B
Syntax Error bcoz of the print statement.
karansOption: B
The answer is B because the print statement isn,t in the correct format Correct format-print() The format they have given - print)
