Top TCS Xplore Python coding questions & answers:

If you are aspiring to explore Python through a self-paced course, try GUVI’s Python certification course with IIT Certification.

Q1. Write a Python code to print the position or index of a given string (taken as input from a user) from a given list of strings.

Ans. The program will take input from the user in the form of a string and will pass the string as an argument to a function. The function will take the strings as arguments and return the Position(or index) of the list if the passed string is present in the list, else it’ll return “String not found”. If the passed strings are present at multiple indices, in that case, the function should only return The first index of occurrence.

Considering the above scenario into account, build the logic to print the position of the passed string from a given list of strings.

Refer to the below instructions and sample input-Output for more clarity on the requirement.

Input:

Hello Good Morning

abcd123Fghy

India

Progoti.c

India

Output:

The position of the searched string is: 2

def isPresent(lis,st):

for i in range(0, len(lis)):

if lis[i] == st:

return i

lis = []

for j in range(int(input())):

lis.append(input())

st = input()

ind = isPresent(lis,st)

if ind == -1:

print(“String not found”)

else:

print(“Position of the searched string is: “,ind)

Q2. Make a function check_palindrome() that takes a list of strings as an argument. It returns the string which is a palindrome.

Input:

malayalam

radar

nitish

Output:

malayalam

radar

code:

def check_palindrome(lis):

palin_lis = []

for i in lis:

if i == i[::-1]:

palin_lis.append(i)

return palin_lis

lis = []

for i in range(int(input())):

lis.append(input())

for _ in check_palindrome(lis):

print(_)

Q3. Create a function count_words() which takes a string as input and creates a dictionary with a word in the string as a key and its value as the number of times the word is repeated in the string. It should return the dictionary.

eg: “hello hi hello world hello”

dict={‘hello’:3,’hi’:1,’word’:1}

Create another function max_accurance_word() which takes a string as input and returns the word which is occurring a maximum number of times in the string. Use the count_words function inside this function.

Sample input:

“hello hi hello world hello”

Sample output:

‘hello’

Code:

def count_words(string):

l=string.split()

s=set(l)

d={}

for i in s:

x=l.count(i)

d[i]=x

return d

def max_occurance(string):

d=count_words(string)

l1=[]

for i in d.values():

l1.append(i)

max1=max(l1)

for i in d.keys():

if d[i]==max1:

return i

string=input()

print(max_occurance(string))

Q5. Write a Python program to calculate the salary of the temporary staff using Multilevel Inheritance.

Description:

Create a class Person which contains a constructor __init__() and a method display(self). The method displays the name of the person

Create another class Staff which inherits Person. It contains a constructor __init__() and a method display(self). The method displays Id.

Create another class Temporarystaff which inherits Staff, it also contains a constructor __init__() and two method displays (self), and Salary(self).
