Write a program that prints all the keys and values in a dictionary where the key is "dennis" and the value is "student."

Program to Find Specific Key-Value Pairs in a Dictionary

1. Break Down the Problem

   • We need to create a dictionary.
   • We will then check for key-value pairs where the key is "dennis" and the value is "student."
   • Finally, we will print those key-value pairs if they exist.

2. Relevant Concepts

   • A dictionary in Python is a collection of key-value pairs.
   • We can iterate over the dictionary items to check for specific keys and values.

3. Implementation

   • Initialize the dictionary.
   • Use a loop to check for the conditions specified (key is "dennis" and value is "student").
   • Print the matching key-value pairs.

# Step 1: Initialize the dictionary
my_dict = {
    "dennis": "student",
    "john": "teacher",
    "mary": "student",
    "dennis": "grade_1"
}

# Step 2: Check for the specific key-value pair
for key, value in my_dict.items():
    if key == "dennis" and value == "student":
        print(f"Key: {key}, Value: {value}")

4. Verify and Summarize
   • This program will print the key and value if the criteria are met. In this case, "dennis" with the value "student" will be printed if it exists in the dictionary.

Final Answer

The output will be:

Key: dennis, Value: student

If "dennis" is associated with any value other than "student," nothing will be printed.
