(PP-2)

2A.Write a function that takes a character (i.e. a string of length 1) and returns True if it is a vowel, False otherwise.

def vowel(x):

    if x in ["a","e","i","o","u"]:

        return True

    else:

        return False

a=int(input("enter an alphabet:"))

print(vowel(a))

2B.Define a function that computes the length of a given list or string.

str="palace world"

str1=list(str)

print(str1)

count=0

for i in str:

    count+=1

print("length of string is :",count)

             or
def findlength(string):
    count=0
    for i in string:
        count+=1
    return count

string="hello world"
print(findlength(string))

2C.Define a procedure histogram() that takes a list of integers and prints a histogram to the screen. For example, histogram([4, 9, 7]) should print the following: 
****
*********
******* 

def histogram(list):
    for a in list:
        print('*'*a)
histogram([4,9,7])

2D.Write a python program to copy a list into another variable.

list=[22,23,24,25,26,29]
list2=list.copy()
print(list)
print(list2)

2E.Write a python program create a list a and print out all the elements from the  list that are less than five.

A=[1,2,3,4,5,6,7,8]
for i  in A:
if i<5:
print(i)

2F.Write a python program to print specified list after removing 0,2,4, & 5th element.

L1=[1,2,3,4,5,6,7]
del L1[0]
del L1[1]
del L1[2]
del L1[2]
print(L1)

2G.Write a python program that takes two list and returns true if they have atleast one common element.

L1=[1,2,3,4,5]
L2=[7,8]
flag=False
for i in L1:
if i in L2:
flag=True
break
if flag:
print("True")
else:
print("False")
            or
def common(list1,list2):
for x in list1:
for y in list2:
if x==y:
result=True
return result
list1=[1,2,3,4,5]
list2=[5,6,7,8,9]
list3=[21,22,23,24,25]
list4=[12,13,14,15]
print(common(list1,list2))
print(common(list3,list4))
