Options

1. 9
2. 3
3. 6
4. 7

Answer- 3

Explanation – x=st.split(\’a\’) x becomes , 

x=[\’C\’, \’dbury D\’, \’iry Milk\’] 

length of x is 3.

Question 2 –

st=”Happy Christmas and Happy new year”

if(st.startswith(“Happy”)):

    x=st.rsplit(“Happy”)

print(len(x))

What is the output of above code?

Options

1. 9
2. 3
3. 6
4. 7

Answer- 3

Explanation –  rstrip()-splits string at specified separator and returns string 

startswith()-returns true if the string starts with specified value.

Question 3 – Which of the following sorts the elements of tuple?

Options

1. sorted(tuple)
2. tuple.sorted()
3. sort(tuple)
4. tuple.sort()

Answer- sorted(tuple)

Explanation – sorted() is used to sort tuple , .sort() function is used for lists 

Question 4 – 

t=(9,10,11,1,11)

s=0

for i in t:

    if(t.count(i)>1):

        s+=(i//2)

    else:

        s+=i*(t.index(i))

print(s)

What is the output of the above code?

Options

1. 19
2. 23
3. 15
4. 17

Answer- 23

Explanation – 

for  i=duplicate element if condition becomes true otherwise false

i=9 ==> s=0+9*0=0

i=10 ==> s=0+10*1=10

i=11 ==> s=10+11//2=15

i=1   ==> s=15+1*3=18

i=11  ==> s=18+11//2=23

S=23

Question 5 – print(ord(‘abc’)) What is the output of the above code?

Options

1. 89
2. 97
3. 65 97
4. error

Answer- error

Explanation –  ord() function accepts only unit length string(character) and returns integer value for a given character.

Question 6 – What is the output of below code?

import math

L = [3, 1, 2, 4]

T = (‘A’, ‘b’, ‘c’, ‘d’)

L.sort()

counter = 0

for x in T:

    L[counter] += ord(x)

    counter += 1

    break

print(math.ceil(max(L)/min(L)))

Options

1. 33
2. 43
3. 67
4. 37

Answer- 33

Explanation –  L is sorted , L=[1,2,3,4]

L[0]+=ord(\”A\”)

where ord(\”A\”) is 65 so L[0] becomes 1+65=66

L=[66,2,3,4]

answer=66/2=33

Question 7 – Which of the following operators can be used on tuples?

Options

1. %
2. /
3. *
4. **

Answer- *

Explanation – Tuples can be multiplied but cant perform power operator(**), division (/) and modulus(%) operations on whole tuple.

Question 8 – Which of the following operators can be used on tuples?

Options

1. %
2. /
3. *
4. **

Answer- *

Explanation – Tuples can be multiplied but cant perform power operator(**), division (/) and modulus(%) operations on whole tuple.

Question 9 – 

l=[1,2,3]

t=(‘a’,’b’,’c’)

s=””

for i in t:

    for j in l:

        if(t.index(i)==l.index(j)):

s+=i*j

print(s.find(“bb”))

What is the output of above code?

Options

1. 1
2. 2
3. 3
4. error

Answer- 1

Explanation – Final S becomes \”abbccc\”

s.find(\”bb\”) gives 1 as \”bb\” presents/starts from index 1

Question 10 – Which of the following is used to create an empty set?

Options

1. []
2. {}
3. ()
4. set()

Answer- set()

Explanation – {} is of class dictionary (print(type({})) try this code for more clarity) and set() is empty set
