• Try to go through the hands on practice questions, and book back programs too

In python programming questions are covered under the topics:

1. List
2. Tuple
3. String slicing
4. Class and object
5. Inheritance
6. Pattern using for loop
7. Pyplot
8. Overloading

Model Program:

1. What will be output of the given python program?

Str= “COMPUTER SCIENCE”

1. a) pirnt(str*2) b) print(str[0:7])
2. What will be the output of the following code?

list=[3**x for x in range(5)]

print(list)

3. Write the output of the following program.

Class hosting:

def__init__(self, name):

self.__name=name

def display(self):

print(“Welcome to”, self.__name)

obj=hosting(“Python programming)

obj.display()

4. What will be the output of the given python program?

a= “computer”

b= “science”

x=a[:4]+b[len(b)-3:]

6. Write the output for the following program.

i=0

while(i<=6):

for j in range(1,i)

print(j, end=’\t’)

print(end= ‘\n’)

i+=1

7. Write the output for the following python commands

Str1= “Welcome to Python”

1. i) print(str1)
2. ii) print(str1[11:17])

iii) print(str1[11:17:2])

1. iv) print(str2[: :4])
2. v) print(str1[: : -4])

8. Write the output for the following python programs

i) j=15

while(j>=10):

print(j, end= ‘\t\’)

j=j-1

else:

print(“\ end of the loop)

ii) k=15

while(k<=9):

for i in range(1,k):

print(i, end= ‘\t\’)

k=k+1

9. Debug the following program to get the given output:

Output:

Inside add() function x value is:10

In main x value is:10

Program:

x=0

define add:

globally x:

x=x+10

print(“inside add()function x value is:”)

add

print(“In main x value is:”)

10. Program to check if the accepted number odd or even

a = int(input(“Enter any number :”))

if a%2==0:

print (a, ” is an even number”)

else:

print (a, ” is an odd number”)

11. Program to access each character with its positive subscript of a giving string

str1 = input (“Enter a string: “)

index=0

for i in str1:

print (“Subscript[“,index,”] : “, i)

index + = 1

12. Program to slice substrings using for loop

str1=”COMPUTER”

index=0

for i in str1:

print (str1[:index+1])

index+=1

13. What will be output of the following python snippet?

Str1=”THOLKAPPIYAM”

Print(str1[4:])

Print(str1[4::2])

Print(str1[::3])

Print(str1[::-3])

14. Draw the chart for the given python snippet.

Import matplotlib. Pyplot as plt

Plt.plot([1,2,3,], [1,4,9,16])

Plt.show()
