A - e

B - a blank space character

C - w

Q 5 - What is the output of the code?

def f():
   global z
   print('z is: ', z)
   z=50
   print('new value of global z is: ', z)

f()
   print('Value of z is: ', z)

A - z is 100

new value of global z is: 100

value of z is 100

B - z is 100

new value of global z is: 100

value of z is 50

C - z is 100

new value of global z is: 50

value of z is 100

D - z is 100

new value of global z is: 50

value of z is 50

Answer : D

Explanation

Here in the above code ‘global' keyword is used to state that ‘z' is global variable. So when we assign a value to z in the function then the new assigned value is reflected whenever we use the value of ‘z' in the main block or outside the function.

Q 6 - What is the output of the following code?

eval(''1 + 3 * 2'')

Answer : D

Explanation

Q 7 - Discuss the outcome of the code?

def func1(n): 
   if(n==0): 
      return 0 
   else: 
      return(n+func1(n-1)) 
def func2(n, result): 
   if(n==0): 
      return(result) 
   else: 
      return(func2(n-1, n+result))  
print(func1(4)) 
print(func2(4,0))

A - Func1 is tail recursion.

B - Func1 and Func2 are tail recursions.

C - Func2 is only tail recursion.

D - Neither Func2 nor Func1 is tail recursion.

Answer : B

Explanation

A function call is said to be tail recursive if there is nothing to do after the function returns except return its value.
