1. Write a program to generate prime numbers
with the help of a function to test prime or not.
def genprime(no):
flag=1
for i in
range(2,no):
if no%i==0:
flag=0
break
return flag
x=int(input("\nEnter
any number"))
ans=genprime(x)
if ans==1:
print("The
number is prime no")
else:
print("The
number is non prime no")
2. Write a python program that removes any
repeated items from a list so that each item appears at most once. For
instance, the list [1,1,2,3,4,3,0,0] would become [1,2,3,4,0].
l=[1,1,2,3,4,3,0,0]
print("The original list is" ,l)
for i in l:
if
l.count(i)>1:
l.remove(i)
print("The updated list is ",l)
3. Write a program to pass a list to a function
and display it.
def myfunction(lst):
print("listvalue in function",lst)
print("id of
list in function",id(lst))
lst.append(10)
print("list
value after updating in function",lst)
print("id of
list after updating in function",id(lst))
lst=[1,2,3,4,5,]
print("list value at calling place",lst)
print("id of list at calling place",id(lst))
myfunction(lst)
print("list value after calling the function",lst)
print("id of list after calling the
function",id(lst))
4. Write a program to demonstrate the use of
Positional argument, keyword
argument and default arguments.
#positional arguments
def posargf(s1,s2):
s3=s1+s2
print(s3)
posargf("abc","def")
posargf("def","abc")
#keyword arguments
def keyargf(rno,name):
print("Roll
no is ",rno, " name is ",name)
keyargf(rno=1,name="def")
keyargf(name="abc",rno=2)
#Default arguments
def defargf(rno,name='***'):
print("Roll
no is ",rno, " name is ",name)
defargf(1,"def")
defargf(2)
5. Write a program to show variable length
argument and its use.
def variargf(farg,*vargs):
print("Formal argument",farg)
for i in vargs:
print("Variable argument",i)
variargf(1)
variargf(1,2,3,4)
variargf(1,"def")
6. Write a lambda/Anonymous function to find
bigger number in two given numbers.
fun=lambda x,y:max(x,y)
ans=fun(5,6)
print("Bigger number is",ans)
7. Create a decorator function to increase the
value of a function by 3.
def decor(fun):
def funinside():
ans=fun()
return(ans*3)
return funinside
def myfunction():
return(10)
finalans=decor(myfunction)
print(finalans())
