Question – 7: Swap values of two variables.
Answer:
#Que 7 - Swaping values of two variables
first = "Jimmy"
second = "Johny"
print("-"*10)
print("Before Swap")
print("-"*10)
print("First = ",first)
print("Second = ",second)
first, second = second, first
print("-"*10)
print("After Swap")
print("-"*10)
print("First = ",first)
print("Second = ",second)
Output:
————–
Before Swap
————–
Jimmy
Johny
————–
After Swap
————–
Johny
Jimmy
Question – 8: Tuples storing the first 9 terms of the Fibonacci series.
Answer:
#Que 8 - Tuples storing the first 9 terms of Fibonacci series
first = 0 #first term
second = 1 #second term
count = 2 # counter is 2 initially
fibterm = first, second #appending first two to tuples
while count < 9:
third = first + second
fibterm += third, #appending third terms to tuple
count += 1
first, second = second, third #swapping
print("Fibonacci Series up to 9th terms ")
print(fibterm)
Output:
Fibonacci Series up to 9th terms
(0, 1, 1, 2, 3, 5, 8, 13, 21)
Question – 9: Dictionary Month and Days. Manipulation of Dictionary
Answer:
month_day = {'Jan':31, 'Feb':28, 'Mar':31, 'Apr':30,
'May':31, 'Jun':30, 'Jul':31, 'Aug':31,
'Sep':30, 'Oct':31, 'Nov':30, 'Dec':31}
#a
month = input("Enter Month Name : ")
print("Number of Days : ", month_day[month])
#b
print("Keys in alphabetical order => ")
month = sorted(month_day.keys())
print(month)
#c
print("Months having 31 days = > ")
for k in month_day:
if month_day[k] == 31:
print(k)
#d
days = sorted(month_day.values())
unique = []
for val in days:
if val not in unique:
unique.append(val)
for val in unique:
for k in month_day:
if month_day[k] == val:
print(k, val)
Output:
Enter Month Name: Jan
Number of Days: 31
Keys in alphabetical order =>
[‘Apr’, ‘Aug’, ‘Dec’, ‘Feb’, ‘Jan’, ‘Jul’, ‘Jun’, ‘Mar’, ‘May’, ‘Nov’, ‘Oct’, ‘Sep’]
Months having 31 days = >
Jan
Mar
May
Jul

Question – 10: Function to Add Two Dictionary, computes the union of two dictionaries
Answer:
#Que 10 - Create a Function addDict() to add two dictionary
def addDict(dict1, dict2):
dict1.update(dict2)
return dict1
d1 = {1 : 'one', 2 :'two'}
d2 = {3 : 'three', 4 : 'four', 1 :'ten'}
print('d1 =>',d1)
print('d2 =>',d2)
d3 = addDict(d1, d2)
print('d3 =>',d3)
Output:
d1 => {1: ‘one’, 2: ‘two’}
d2 => {3: ‘three’, 4: ‘four’, 1: ‘ten’}
d3 => {1: ‘ten’, 2: ‘two’, 3: ‘three’, 4: ‘four’}
