when there is a deviation from the rules of a programming language, a semantic error is thrown

true

false

Q8 | An exception is

an object

a special function

a standard module

a module

Q9 | exceptions are raised as a result of an error in opening a particular file.

valueerror

typeerror

importerror

ioerror

Q10 | Which of the following blocks will be executed whether an exception is thrown or not?

except

else

finally

assert

Q11 | Which of these definitions correctly describes a module?

denoted by triple quotes for providing the specification of certain program elements

design and implementation of specific functionality to be incorporated into a program

defines the specification of how it is to be used

any program that reuses code

Q12 | Which of the following is not an advantage of using modules?

provides a means of reuse of program code

provides a means of dividing up tasks

provides a means of reducing the size of the program

provides a means of testing individual parts of the program

Q13 | Program code making use of a given module is called a of the module.

client

docstring

interface

modularity

Q14 | is a string literal denoted by triple quotes for providing the specifications of certain program elements.

interface

modularity

client

docstring

Q15 | Which of the following is true about top- down design process?

the details of a program design are addressed before the overall design

only the details of the program are addressed

the overall design of the program is addressed before the details

only the design of the program is addressed

Q16 | In top-down design every module is broken into same number of submodules.

true

false

Q17 | All modular designs are because of a top- down design process.

true

false

Q18 | Which of the following is not a valid namespace?

global namespace

public namespace

built-in namespace

local namespace

Q19 | Which of the following is false about “import modulename” form of import?

the namespace of imported module becomes part of importing module

this form of import prevents name clash

the namespace of imported module becomes available to importing module

the identifiers in module are accessed as: modulename.identifier

Q20 | Which of the following is false about “from-import” form of import?

the syntax is: from modulename import identifier

this form of import prevents name clash

the namespace of imported module becomes part of importing module

the identifiers in module are accessed directly as: identifier

Q21 | Which of the statements about modules is false?

in the “from-import” form of import, identifiers beginning with two underscores are private and aren’t imported

dir() built-in function monitors the items in the namespace of the main module

in the “from-import” form of import, all identifiers regardless of whether they are private or public are imported

when a module is loaded, a compiled version of the module with file extension .pyc is automatically produced

Q22 | What is the order of namespaces in which Python looks for an identifier?

python first searches the global namespace, then the local namespace and finally the built- in namespace

python first searches the local namespace, then the global namespace and finally the built-in namespace

python first searches the built-in namespace, then the global namespace and finally the local namespace

python first searches the built-in namespace, then the local namespace and finally the global namespace
