Answer:
Following are the program in the Python Programming Language:
#set dictionary
d = { 'State' : 'Delhi', 'Country' : 'India'};
#reverse the dictionary.
revers = dict((v, k) for k, v in d.items())
#Displays the reversed dictionary.
print("Dictionary is: \n")
print(revers)
<u>Output</u>:
Dictionary is:
{'Delhi': 'State', 'India': 'Country'}
Explanation:
Here, we set the dictionary data type variable "d" then, we set the variable in which we store the reverse of the dictionary in which key is converted into the value and value is converted into the key. and finally we print the reverse dictionary.

Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
<em>else:</em>
<em> print("Positive integer only")</em>
