[2] The following code is saved in a file mod.py (using python 3.X version):

---

def printHi():
    print ("Hi")

Now consider the following interaction on Python console, assuming mod.py 
is in the current directory where the console is invoked:

>>> import mod
>>> printHi()
Traceback
(most recent call last):  File "", line 1, in 
NameError: name 'printHi' is not defined

What is the reason for the NameError error?

(a): printHi is a keyword in Python
(b): printHi is not a valid function name
(c): We need to qualify function name with module name, as mod.printHi()
(d): import does not import files in the current directory

Answer: (c) We need to qualify function name with module name, as mod.printHi()

[3] The following code is saved in a file mod.py (using python 3.X version):

def printHi():
    print ("Hi")

Now consider the following interaction on Python console, assuming 
mod.py is in the current directory where the console is invoked:

>>> import mod
>>> print (mod.__name__)

What will be the output on the console?

(a): Hi
(b): mod.Hi
(c): mod
(d): Error since __name__ is not defined

Answer: (c) mod

         ... # suitable code

(a): A

(b): B

(c): C

(d): D

Answer: (c) C

Suppose we have a python module as file mdl.py defining three functions f1, f2 and f3. Now we give the following python command at the python shell:

---

Which of the following functions from mdl.py can be invoked from calling script -

(a): only f1 and f3

(b): only f2 and f3

(c): only f3 and f1

(d): all of f1, f2 and f3

Answer: (d) all of f1, f2 and f3

What is the output of the following python code?

---

class hello:
     def __init__(self,a="Visit Prutor.ai website"):
         self.a=a

     def display(self):

What is the output of the following python code?

---

class test:

        print(self.x)
obj=test()
obj.display()

(a): Executes normally and doesn’t display anything

(b): Displays 0, which is the automatic default value
