Sample Solution:

Python Code:

# Create a dictionary 'num' with subject names as keys and corresponding marks as values.
num = {'physics': 80, 'math': 90, 'chemistry': 86}

# Print a message indicating the intention to access the keys of the dictionary and retrieve them as a list.
print("\nAccess the keys of the dictionary as a list:")

# Access and print the first key (subject name) in the dictionary.
print(list(num)[0])

# Access and print the second key (subject name) in the dictionary.
print(list(num)[1])

# Access and print the third key (subject name) in the dictionary.
print(list(num)[2])

Sample Output:

Access the keys of the dictionary as a list:
physics
math
chemistry
