 ASSERTION & REASONING
1. A: The function header ‘def read (a=2, b=5, c):’ is not
correct.
R: Non default arguments can’t follow default arguments.
2. A function code is given as follows:
def study (num = 5):
print(num + 5)
A: We can call the above function either by statement
'study(7)' or 'study( )'.
R: As the function contains default arguments, it depends
on the caller that the above function can be called with
or without the value.
3. A: len( ), type( ), int( ), input( ) are the functions that are
always available for use.
R: Built in functions are predefined functions that are
always available for use. For using them we don’t need
to import any module.
4. A:
def Disp(x,y,z):
print(x+y+z)
z=10
Disp(x=67,y=78,z)

R: The above code depicts the concept of keyword

argument. But, during execution it will show an error.
5. A: Every function returns a value if the function does not
explicitly return a value, then it will return ‘Zero’.
R: Zero is equivalent to None.
6. A: A function is a block of organized and reusable code
that is used to perform a single related action.
R: Function provides better modularity for your
application and a high degree of code reusability.
7. Consider the following code:
x = 100
def study( ):
global x
x = 50
print(x)
study()
A: 50 will be the output of above code.
R: Because the x used inside the function study( ) is of
local scope.
8. A: The number of actual parameters in a function call may
not be equal to the number of formal parameters of the
function.
R: During a function call, it is optional to pass the values
to default parameters
9. A: The function definition calculate (a, b, c=1, d) will give
error.
R: All the non-default arguments must precede the default
arguments.
10. A: Key word arguments are related to the function calls
R: When you use keyword arguments in a function call,
the caller identifies the arguments by the parameter
name.
11. A: The default arguments can be skipped in the function
call.
R: The function argument will take the default valueseven
if the values are supplied in the function call
12. A: global keyword is used inside a function to enable the
function alter the value of a global variable.
R: A global variable cannot be accessed by a function
without the use of global keyword.
13. A: Keyword arguments were the named arguments with
assigned values being passed in the function call.
R: Default arguments cannot be skipped while calling the
function while keyword arguments are in function call
statement.
14. A: Keyword arguments are related to function calls.
R: When you use keyword arguments in a function call, the
caller identifies the arguments by the values passed.
15. A: If the arguments in function call statement match
the number and order of arguments as defined in the
function definition, such arguments are called
positional arguments.
R: During a function call, the argument list first contains
default argument(s) followed by positional argument(s).
16. A: A function header has been declared as
def MYFUN(A, B=30):
The function call MYFUN(20, 60, B=80)
will give an error.
R: During a function call, the same parameter
should not be provided two values.

17. A: The writerow function of csv module takes a

list having length equal to the number of
columns in CSV file.
R: The data inside a CSV file is stored in the
form of a string.
18. A: Python allows function arguments to have default
values; if the function is called without the argument,
the argument gets its default value.
R: During a function call, the argument list first contains
default argument(s) followed by positional argument(s).
19. A: A CSV file stores data in rows and the values in
each row is separated with a separator, also known as
a delimiter.
R: You cannot change the by default comma as a value
separator.
20. A: Global variable is declared outside the all the
functions.
R: It is accessible through out all the functions.
21. A: If the arguments in function call statement
match the number and order of arguments
as defined in the function definition, such
arguments are called positional arguments.

R: During a function call, the argument list first contains

default argument(s) followed by positional argument(s).
22. A: A variable is still valid if it is not defined inside the
function. The values defined in global scope can be
used.
R: Python used LEGB rule to resolve the scope of a
variable.
23. A: When passing a mutable sequence as an argument,
function modifies the original copy of the sequence.
R: Function can alter mutable sequences passes to it.
24. A: Key word arguments are related to function calls.
R: When you use keyword arguments in function call, the
caller identifies the arguments by the parameter name.
25. A: Keyword arguments are related to the function calls
R: When you use keyword arguments in a function call,
the caller identifies the arguments by the parameter
name.
