Question

Question 1 (25pts):

Consider the string “data and program analytics”. Write a program to perform the following actions

• Find the index of the character ‘p’ in the given string
• Print the character which is present at index number seven
• Find the length of the String
• Split the string at every occurrence of a whitespace
• Replace the word “data” in the original string with “information” using a standard string manipulation function. Your output after the manipulation should be “information and program analytics”

Question 2 (15 pts):

List1 = [3, 4, 5, 20, 5]

• Find the index of the second 5
• Find the last element of this list

Question 3 (15 pts):

Set1 = {1, 2, 3, 4}, Set2={4, 5, 6}

• Print all elements that appear in both sets
• Print those elements that appear in either set
• Print all elements that appear in Set1 but not Set2

Question 4 (15 pts):

L = [('',), (), ('apple', 1), (), ("Paul", "Merage', 2020, "MSBA212"), ("d")]

Write a Python program to remove an empty tuple(s) from a list of tuples.

Expected outcome is:

[('',), ('apple', 1), ('Paul', 'Merage', 2020, 'MSBA212'), 'd']

Question 5 (15 pts):

• Reverse words in the string "one apple a day keeps the doctors away" and print the new string
• Sort the words in the string "one apple a day keeps the doctors away" alphabetically and then print the new string.

Question 6 (15 pts):

Two given lists [1,2,4,8,5,10] and [2,4,5,8,12,15], write a program to make a list whose elements are intersection of the above given lists.

Answer 1

Question 1)

s="data and program analytics"
print("The index of character p is :",s.index('p'))
print("The character at index 7 is :",s[7])
print("The length of the string is :",len(s))
l=s.split(" ")
print("The string is split to list of words at occurence of white space:",l)
s=s.replace("data","information")
print("The string after replacement is :",s)

OUTPUT:

Question 2)

List1 = [3, 4, 5, 20, 5]
print("The index of second 5 is :",end="")
c=0
for i in range(len(List1)):
if List1[i]==5:
c+=1
if c==2:#if it is second 5 then print the index i
print(i)
print("Tha last element of the list is :",List1[-1])#print the last element

OUTPUT:

Question 3)

Set1 = {1, 2, 3, 4}
Set2={4, 5, 6}
print("The elements that appear in both the sets are :",Set1.intersection(Set2))
print("The elements that appear in either of the sets are:",Set1.union(Set2))
print("The elements that appear in set1 but not set2 are: ",Set1-Set2)

OUTPUT:

Question 4)

L = [('',), (), ('apple', 1), (), ("Paul", "Merage", 2020, "MSBA212"), ("d")]
i=0
while i<len(L):
if len(L[i])==0:#if tuple is empty then pop it
L.pop(i)
i+=1
print(L)

OUTPUT:

Question 5)

s="one apple a day keeps the doctors away"
l=s.split(" ")
newstring=[]
for i in range(len(l)-1,-1,-1):
newstring.append(l[i])#store the words in reverse order
print(' '.join(newstring))#print the string
l.sort()
print("The sorted string is: ",end="")
print(' '.join(l))#print the string after sorting

OUTPUT:

Question 6)

res=[]
l1=[1,2,4,8,5,10]
l2=[2,4,5,8,12,15]
for i in l1:
if i in l2:#if element is in both lists then add it to res list
res.append(i)
  
print("The intersection of above two lists is :",res)

OUTPUT:
