Python Skill Assessment by Media - Chennai Company - Techgig

In this post, I am giving you the  Python multiple questions and answers asked by the Media , an Chennai company in Techgig website.

1)  The output of 10 // 6 is 1 (// represents floor division and gives integer value of the quotient)

2) The output of below program is 

import itertools

L1 = (1,2,3)

L2 = [4,5,6]

Iter = itertools.chain(L1,L2)

print(next(L1))

tuple is not an iterator

3) Use of __slots__ in Python - Special Mechanism to reduce the size of the objects

4) The output of below program is “Bye World”

class test:

 def __init__(self):

   print("Hello World")

 def __init__(self):

   print("Bye World")

obj = test()

5) The output of below program is [3,2,1]

L = [[9,8,7],[6,5,4],[3,2,1]]

print(L[2])

6) The output of print(chr(ord('b')+1)) is c

7) The output of below program is [0,1,2,3,4]

def f(x):

 for i in range(5):

   yield i

g = f(8)

print(list(g))

8) The output of print("{:,}".format(1112223334)) is 1,112,223,334

9) The output of below program is [0,2,4]

a = [x for x in range(5)]

b= [x for x in range(7) if x in a and x % 2 == 0]

print(b)

10) Use of seek() in files - Set file current position at the offset

11) Pandas Dataframe can accept Structured ndarray, Series & DataFrame as inputs

12) Scikit-learn is a library used for Machine learning in Python

13) The output of the below program is ['mango', 'apple', 'orange']

word ='mango,apple,orange'

print(word.split(","))

14) The file that should be present inside the package is __init__.py

15) Function used to close a file in python - close()

16) Slicing in Python - creates slice object representing set of indices specified by range(start,stop,step)

17) Numpy function that returns its argument with a modified shape - reshape

      Numpy function that modifies array itself - resize

18) Python supports Automatic Garbage Collection & can be easily integrated with C, C++, COM, ActiveX, COBRA and Java

19) Can we add an element to a = (1,2,3,4,5). No,a is a tuple and cannot insert an element

20) The output of the below program is 

import re

sentence = 'horses are fast'

regex = re.compile('(?P<animal>\w+) (?P<verb>\w+) (?P<adjective>\w+)')

matched = re.search(regex, sentence)

print(matched.groupdict())

{'animal': 'horses', 'verb': 'are', 'adjective': 'fast'}
