Sample Solution:

Python Code:

# Create a set 'setn' with elements 5, 10, 3, 15, 2, and 20.
setn = {5, 10, 3, 15, 2, 20}

# Print a message to indicate the original set elements.
print("Original set elements:")

# Print the contents of 'setn'.
print(setn)

# Print the type of 'setn'.
print(type(setn))

# Print a message to indicate finding the length of the set.
print("\nLength of the said set:")

# Use the 'len()' function to find and print the length (number of elements) of 'setn'.
print(len(setn))

# Create a set 'setn' with repeated elements, all 5.
setn = {5, 5, 5, 5, 5, 5}

# Print a message to indicate the original set elements.
print("Original set elements:")

# Print the contents of 'setn'.
print(setn)

# Print the type of 'setn'.
print(type(setn))

# Print a message to indicate finding the length of the set.
print("\nLength of the said set:")

# Use the 'len()' function to find and print the length of 'setn', which will be 1 due to duplicates being removed in a set.
print(len(setn))

# Create a set 'setn' with repeated elements, all 5 and an additional element 7.
setn = {5, 5, 5, 5, 5, 5, 7}

# Print a message to indicate the original set elements.
print("Original set elements:")

# Print the contents of 'setn'.
print(setn)

# Print the type of 'setn'.
print(type(setn))

# Print a message to indicate finding the length of the set.
print("\nLength of the said set:")

# Use the 'len()' function to find and print the length of 'setn', which will be 2 due to duplicates being removed and the additional element.
print(len(setn))

Sample Output:

Original set elements:
{2, 3, 5, 10, 15, 20}
<class 'set'>

Length of the said set:
6
Original set elements:
{5}
<class 'set'>

Length of the said set:
1
Original set elements:
{5, 7}
<class 'set'>

Length of the said set:
2
