Python Online Practice Test - 5

This Test will cover complete Python with very important questions, starting off from basics to advanced
level.
Q. A group of developers,were discussing the various options,for interacting with websites,through code.
Following points were stated -
DevA - While using urllib,one can use the method urlencode,for generation of GET query strings.The
Requests module,does the encoding automatically.Urllib2 also has urlencode method.
DevB - Only urllib module, has an urlencode function.Requests module,handles error very
well,whereas,the urllib2 raises an URLError,if the authentication fails.
DevC - Both urllib2 and Requests module,raise an URLError,when authentication fails.The urlencode()
method,is present in urllib2 and not in urllib module.
Mark the correct statement.

A. Dev B is correct about URLError whereas Dev A is wrong about urlencode function

B. Dev C is totally wrong.

C. Dev A is totally correct.

D. Dev C is correct about urlencode function,whereas DevB is wrong about URLError.
Correct Answer : OPTION B, Python Requests module,encode requests automatically.For generation of GET
query strings, method urlencode() present in urllib,is used. No such method is present in urllib2.Urllib2
raises an URLError,if any authentication fails, whereas, Requests module simply returns a response
object,in such a scenario.Thus it handles errors well.
Q. A developer was debugging,a Python program,using the pdb module.Below are some descriptions,of the
debug commands:

1) List the source code. B. <c> , <a> ,<n> ,<r>
2) Add a breakpoint. D. <s> ,
,<d> ,<e>
3) Debug step by step.
4) Resume execution.
Match them with their actual command.

A. <n> ,

,<s> ,<x>

C. <l> , <b> ,<s> ,<c>

Correct Answer : OPTION C, Pdb module,is used to debug a Python program. Different pdb commands,are
used to perform, various operations.
Q. A developer was working on Dictionary data structure in Python3. He executed the following code
snippets:

#1

City1 = {'Pune': 25,'Benguluru':30,'Delhi':40}
City2 = {'Delhi':38}
print(cmp(City1,City2))

#2
City1 = {'Pune': 25,'Benguluru':30,'Delhi':40}
del City1{'Pune'}
print(City1)

Mark the correct output.
A. 1) cmp method does not exists in Python3 2) SyntaxError :invalid syntax
B. 1) 1 2) {'Benguluru':30,'Delhi':40}
C. 1) -1 2) SyntaxError : Key cannot be deleted individually
D. 1) SyntaxError 2) SyntaxError: Delete not supported for dictionary

Correct Answer : OPTION A, The cmp method is present in Python2 but not in Python3. It should be
implemented,by the developer,if needed. The delete function,can be applied,to individual elements of
Dictionary. It should be used as del dict_name(key name).
Q. A developer was solving a worksheet of regex problems. He came across the following:

import re
print((re.split(r'\s','funday is sunday')))
print((re.split(r's','fun is sunday')))
print((re.split(r'\d','sunday 3 times a week')))

Mark the correct output of the print statements.
A. ['funday', 'is', 'sunday'] ['funiunday'] ['sundaytimesaweek']
B. [ 'is', 'sunday'] ['s ','s'] ['3']
C. ['fundayi', 'ss', 'unday'] ['fun', 'i ', 'sunday'] ['sunday','3', ' times a week']
D. ['funday', 'is', 'sunday'] ['fun i', ' ', 'unday'] ['sunday ', ' times a week']

Correct Answer : OPTION D, The \s expression,is used to create a space in the string. When the ' \' is
removed,from the string,only alphabet 's' is removed from the output.The '\d' expression,removes the
digits present in the string.
Q. A developer was teaching his team,about the different socket methods,found in network
programming.Below are few descriptions of the same:
1) This method,sends the User Datagram Protocol(UDP) message.
2) This method,sends a TCP message.
3) This method,receives a UDP message.
4) This method,starts the TCP listener.
Map them with the actual method names.(s is the socket object).
A. s.sendto(), s.send(),s.recevfrom(),s.listen()
B. s.send(), s.send(),s.get(),s.start()
C. s.send(int udp), s.send(int tcp),s.receive(),s.listen()
D. s.sendto(), s.send(),s.recev(),s.start()
Correct Answer : OPTION A, Python has multiple methods,for the server and client sides.Sockets allow to
communicate, between processes, present on same or different machines, or within, a process.

for city in mylist:

city.lower()
print(mylist)

#2
print(bool('False'))

#3
statement="Number of continents are "
value = 7
print(statement+value)

Mark the correct output.
A. 1) ['pune',mumbai','delhi'] 2) False 3) SyntaxError.
B. 1) ['PUNE','MUMBAI','DELHI'] 2) True 3) TypeError
C. 1) TypeError 2) [] 3) Number of continents are 7.
D. 1) SyntaxError 2) TypeError 3) Number of continents are 7.

Correct Answer : OPTION B, The new lower case list,returned is not stored anywhere. Hence the original

mylist list is printed. If any value,is passed to bool() function,it returns true.Concatenation of string and

integer,is not allowed. Hence the 3rd code snippet throws TypeError.

Q. A developer had to mark,the following statements,related to Multithreading in Python,as True or False:

1) RLock can be acquired,by the same thread,multiple times.

2) Acquired Lock,can be released,only by the thread,that acquired it.

C. 1st and 3rd are correct steps. 2nd and 4th are incorrect

D. Except 2nd all steps are valid.

Correct Answer : OPTION C, The xml.dom.minidom module,should be imported, to parse a XML file.The

xml.dom.minidom.parse(xml name) function,is used to load and parse the XML file. The

firstChild.tagname,can be used to print,the name of the firstchild of the document node.
