pyhton unit-2 programs

 

Program-1:

Aim: Write a python program to define a function with multiple return values.

Program:

def operations(x,y):

    sum=x+y

    sub=x-y

    mul=x*y

    return sum,sub,mul

sum,sub,mul=operations(25,15)

print("sum:",sum)

print("sub:",sub)

print("mul:",mul)

Output:

(Or)

def operations(x,y):

    sum=x+y

    sub=x-y

    mul=x*y

    return sum,sub,mul

sum,sub,mul=operations(25,15)

print("sum:",sum)

print("sub:",sub)

print("mul:",mul)






program-2:

Aim: Write a python program to define a function using default arguments.

Program:

def defaultArgs(a=10,b=15,c=30):

    print(a,b,c)

    return

defaultArgs()

Output:

(or)

def area_rect(height=1,length=1):

    area=height*length

    print(area)

area_rect(10,10)

output:





Program-3:

Aim: Write a python program to find the length of the string without using any library functions.

Program:

string=input("Enter the string:")

count=0

for i in string:

    count=count+1

print("Length of the given string is: ", count)

Output:







Program-4:

Aim: Write a python program to check if the substring is present in the given string.

Program:

s1=input("Enter String:")

s2=input("Enter Sub_string:")

if(s1.find(s2)==-1):

    print("Sub_string not found in s1.")

 

else:

    print("Sub_string in s1.")

output:

Enter String:hai python programming

Enter Sub_string:python

Sub_string in s1.

 

 

 

 

 

 

 

Program-5:

Aim: Write a python program to perfrom the given operations on a list.

1)Addition 2)insertion 3)slicing

Program:

list = [10, 20, 30, 40, 50]

print("Actual list:",list)#Initialize

list.append(60)

print("After addition:",list)# Addition

list.insert(2, 25)

print("After insertion:",list)# Insertion

sublist = list[1:4]

print("Sliced list:", sublist)#Slicing

output:






Program-6:

Aim: Write a python program to perform any 5 built-in functions by taking any list.

Program:

list=[10,20,30,40,50]

print("Acutal:",list)

list.append(60)

print("After append:",list)

list.remove(20)

print("After remove:",list)

pop=list.pop()

print("pop element:",pop)

print("After pop:",list)

list.sort()

print("After sort:",list)

list.reverse()

print("After reverse:",list)

output:
