A function checkMain() defined in module Allchecks.py is being used in two different programs. In program 1 as Allchecks.checkMain(3, 'A') and in program 2 as checkMain(4, 'Z'). Why are these two function-call statements different from one another when the function being invoked is just the same ?

Given below is semi-complete code of a module basic.py :

#
"""..............."""  
def square(x):
"""..............."""
    return mul(x, x)
...............mul(x, y):
"""..............."""
    return x * y
def div(x, y):
    """..............."""
    return float(x)/y
...............fdiv(x, y)...............
"""..............."""
...............x//y
def floordiv(x, y)...............
...............fdiv(x, y)

Complete the code. Save it as a module.

Import the above module basic.py and write statements for the following :

(a) Compute square of 19.23.

(b) Compute floor division of 1000.01 with 100.23.

(c) Compute product of 3, 4 and 5. (Hint. use a function multiple times).

(d) What is the difference between basic.div(100, 0) and basic.div(0, 100)?

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.
