Assertion (A): Exception handling code is separate from normal code.

Reasoning (R): Program logic is different while exception handling code uses specific keywords to handle exceptions.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Assertion (A): Exception handling code is clear and block based in Python.

Reasoning (R): The code where unexpected runtime exception may occur is separate from the code where the action takes place when an exception occurs.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

What all can be the possible outputs of the following code?

def myfunc (x=None) :
    result = "" 
    if x is None:
       result = "No argument given"
    elif x == 0: 
       result = "Zero"
    elif 0 < x <= 3:
       result = "x is between 0 and 3"
    else:
       result = "x is more than 3"
    return result 
c = myfunc (3.5) 
    print (c)
