Suppose that after we import the random module, we define the following function called diff in a Python session :

def diff():
    x = random.random() - random.random() 
    return(x)

What would be the result if you now evaluate

y = diff()
print(y)

at the Python prompt ? Give reasons for your answer.

What are the possible outcome(s) executed from the following code? Also specify the maximum and minimum values that can be assigned to variable NUMBER.

STRING = "CBSEONLINE"
NUMBER = random.randint(0, 3)
N = 9
while STRING[N] != 'L' :
    print(STRING[N] + STRING[NUMBER] + '#', end = '') 
    NUMBER = NUMBER + 1
    N = N - 1

1. ES#NE#IO#
2. LE#NO#ON#
3. NS#IE#LO#
4. EC#NB#IS#

Consider the following code :

import random
print(100 + random.randint(5, 10), end = ' ' ) 
print(100 + random.randint(5, 10), end = ' ' ) 
print(100 + random.randint(5, 10), end = ' ' ) 
print(100 + random.randint(5, 10))

Find the suggested output options 1 to 4. Also, write the least value and highest value that can be generated.

1. 102 105 104 105
2. 110 103 104 105
3. 105 107 105 110
4. 110 105 105 110

Consider the following package

music/                        Top-level package
 ├── __init__.py
 ├── formats/                 Subpackage for file format
 │      ├── __init__.py
 │      └── wavread.py
 │      └── wavwrite.py
 │
 ├── effects/                 Subpackage for sound effects
 │      └── __init__.py
 │      └── echo.py
 │      └── surround.py
 │      └── reverse.py
 │
 └── filters/                 Subpackage for filters
     ├── __init__.py
     └── equalizer.py
     └── vocoder.py
     └── karaoke.py

Each of the above modules contain functions play(), writefile() and readfile().

(a) If the module wavwrite is imported using command import music.formats.wavwrite. How will you invoke its writefile() function ? Write command for it.

(b) If the module wavwrite is imported using command from music.formats import wavwrite. How will you invoke its writefile() function ? Write command for it.
